# Changelog

All notable changes to Jarl are documented here. The format follows
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and versions follow
[Semantic Versioning](https://semver.org/).

## [Unreleased]

### Added

- Disabled zones: a zone can be disabled instead of deleted. named stops
  loading it (its zone statement is left out of named.conf), while Jarl
  keeps it with its records, options and history, still editable;
  enabling it serves it as it is then. Disabling says what clients get
  instead (recursion, or REFUSED). Signed zones can't be disabled. Web
  UI: Disable/Enable on the zone page, a badge in the zone list. CLI:
  `jarl zone disable|enable`. API: `PATCH /zones/{zone}` with
  `{"disabled": true}`. Database schema 7.
- Blocking (docs/blocking.md): named answers "doesn't exist" for ads,
  trackers and malware, using BIND's response policy zones.
  - Blocklists in Adblock, hosts or plain-domain format, downloaded by jarld
    and checked daily (`blocking.refresh`). A list is downloaded only when
    the server says it changed, checked with named-checkzone, and reloaded
    only when its content differs; a failed update keeps the previous
    version and shows on the dashboard.
  - Your own block and allow rules, for a domain and the names below it or
    the exact name. Rules take precedence over every list, and the most
    specific rule wins.
  - Lists and rules apply to chosen views, or to every view that offers
    recursion. They are configuration: staged, reviewed and reverted like
    any change.
  - Checking a name says whether it is blocked and by which rule or list
    entry, with an Allow button in the web UI.
  - Web UI: a Blocking page, with well-known lists to pick and named's
    memory per list. CLI: `jarl blocklist` and `jarl block`. API:
    `/blocking/lists`, `/blocking/rules`, `/blocking/check`.
  - Pausing: `jarl block pause [DURATION]` or the Blocking page lets every
    name through for a while (at most a day); blocking resumes by itself.
    The lists stay loaded, so it takes effect at once.
  - Statistics: blocked queries over time (a line on the queries chart)
    and their share, blocked per list, the most blocked names and the
    clients with the most blocked queries (`jarl stats top blocked`,
    `top blocked-clients`). Blocked answers no longer count as names that
    don't exist.
  - The view choice in the web UI's forms is a compact dropdown, however
    many views there are.
  - A `blocking` permission; database schema 6.

### Changed

- Options are kept in one fixed order, in named.conf, the web UI and the
  CLI: grouped by topic (files, listening, access control, recursion and
  forwarding, DNSSEC, transfers and notify, then the rest), alphabetical
  within a group. The same option is now in the same place in every view
  and zone. The first apply after upgrading reorders named.conf (a diff
  that only moves lines). Top-level statements keep their order.
- Diffs of named.conf say which block each change is in, after the `@@`
  line numbers (`@@ -50,6 +49,8 @@ view "internal" {`), like git does
  with function names. Moving an option from the server's options into a
  view no longer looks like two unrelated edits.
- Web UI options (server, top-level, view and zone): values with blocks,
  such as logging, are shown and edited laid out as in named.conf, over
  several lines with indentation. The editor grows with its content, Tab
  indents and Enter keeps the indentation (Esc, then Tab, moves on). With
  a draft open, the tables show the draft's values, so a staged edit stays
  visible after Save.
- The pending-changes banner has an Apply now button: it applies your
  draft without going to the Changes page, and stays on the page you're
  on. If the changes are refused, a dialog says why and links to Changes.
- Blocking page: blocklists and rules have an Edit button (name, URL,
  views, comment; a rule's action and scope). The list button that
  downloads now is called Refresh, like `jarl blocklist refresh`.
- Records table: disabled records are hatched and have a "disabled" badge
  next to their name, instead of only a muted colour and a badge in the
  comment column.

### Fixed

- Statistics: after a reconfig that added, removed or recreated views
  (creating the first view, for instance), a minute could count everything
  since named started: millions of queries in an hour. A per-view counter
  (cache, upstream times, validation) going down was taken for a restart
  of named. Now only a new boot time means a restart, and a counter that
  goes down counts 0 for that minute.
- Blocking page, checking a name: when your own block rule is for that very
  name, it offers to remove the rule instead of an allow rule, which was
  refused as a second rule for the same name. It also names the rule that
  matched rather than the policy zone entry.
- docs/validation.md lacked the `disabled_conflict` warning added in 0.3.0.

## [0.3.0] - 2026-10-09

### Added

- Disabled records: a record can be disabled instead of deleted. It stays
  in Jarl with its ID, TTL and comment but is left out of the zone (the
  zone file lists it as a comment), and enabling it puts it back exactly
  as it was. Web UI: a Disable/Enable button on each record, disabled
  records greyed out with a badge, a filter for them, and a count in the
  zone list. CLI: `jarl record disable|enable` (by ID or by name, type and
  data, `--ptr` for the PTR record, `--missing-ok`), `record list
  --disabled`, and `disable:`/`enable:` entries for `jarl apply -f`. API:
  `POST /records/{id}/disable|enable`, `POST
  /zones/{zone}/records/disable|enable`, a `disabled` field on records,
  `?disabled=` on record lists and `record.disable|enable` operations.
  Validation checks the zone as it is served: the last NS record can't be
  disabled, enabling a record is checked like adding it, and a disabled
  record that a CNAME now blocks gets a warning. Database schema 5.
- DNSSEC for a zone whose parent zone is in Jarl: the DNSSEC tab gives the
  `jarl record add PARENT NAME DS ...` command to copy and an "Add to
  PARENT" button (staged like any change), links to the parent zone, and
  says when the parent has the DS record. `jarl zone dnssec status` prints
  the command too, and turning signing off gives the matching `jarl record
  delete`.

- CLI output for scripts: `-o id` prints just the IDs of what a command
  shows or lists (`jarl zone show adbraun.lol -o id`), `-o
  field=view,soa.serial` just those fields, tab separated. `-q` on `show`
  and `list` prints the IDs too. With a change (`jarl record add ... -o
  id`) they apply to the changed object.

- Statistics: client lists (busiest and refused clients, in the web UI,
  `jarl stats top clients|refused` and `jarl stats summary`) show the host
  name Jarl's records have for each address: the PTR record's target, or
  else the name of an A/AAAA record. Looked up in Jarl's own data, so no
  DNS queries; an address without a record shows as before.
- Zones list: a padlock after each signed zone's name, linking to its
  DNSSEC tab (open and amber while signing is being turned off).

### Changed

- The web UI and API can listen on ports below 1024, such as 443:
  `jarl.service` now gives jarld the `CAP_NET_BIND_SERVICE` capability
  (and only that). With a unit that doesn't, jarld's error says what's
  missing. See docs/configuration.md, "HTTPS on port 443".
- Records table: names are no longer greyed out when they repeat the row
  above (it made those records look inactive). Records of the same name
  are separated by a faint line instead, and a full line marks where the
  next name starts.

### Fixed

- `jarl record list`: one long value (a DKIM key) padded every row to its
  length, so on a terminal each row wrapped onto a second, blank-looking
  line. Long data is now shortened to fit the terminal; `--wide` shows it
  in full, as does output to a pipe or file.

## [0.2.0] - 2026-10-09

### Added

- DNSSEC signing per zone (docs/dnssec.md): `jarl zone dnssec
  enable|status|check-ds|disable|wipe` and the zone page's DNSSEC tab, or
  the zone's new `dnssec_policy` field in the API. named signs the zone
  with BIND's `default` policy (one ECDSA P-256 key that is never replaced)
  or a custom one, using inline signing, with keys in a per-view directory
  under `/var/lib/bind/jarl/dnssec-keys`. Jarl shows the keys and the DS
  record to give the registrar, says when it's safe to publish it, and
  checks the parent's DS records (`check-ds`, which also tells named with
  `rndc dnssec -checkds`). It refuses steps that would break a signed
  domain: switching straight to unsigned (it goes through BIND's
  `insecure` policy instead, and finishes only once named is done),
  deleting a signed zone or moving it to another view, and TTLs above the
  policy's `max-zone-ttl`. `wipe` starts over with a clean slate once the
  parent has no DS. Each step in the web UI opens a dialog that says what it
  needs first. `jarl zone delegation` now also compares the parent's DS
  records with the zone's keys.
- Porkbun support (optional, docs/dnssec.md#porkbun): with an API key in
  the new `porkbun:` section of jarl.yaml (and nowhere else), `jarl zone
  registrar status|sync-glue|set-ns|publish-ds|remove-ds` and the zone
  page's Registrar tab show and change the domain's name servers, glue
  records (one per name server inside the domain, with all its IPv4 and
  IPv6 addresses) and DS records at Porkbun. Every change first checks that
  it won't take the domain offline (the name servers answer for the zone,
  glue matches, a DS goes out only once the domain is delegated to servers
  that serve the signed zone, DS records match the zone's keys before the
  name servers change); `--dry-run` shows the checks and `--force` skips
  them. Administrators only.
- Backups include the DNSSEC keys (private keys too), stored inside the
  backup file, and `jarld restore` puts them back for named
  (`bind.named_user`, default `bind`). `jarl-backup.service` has
  `CAP_DAC_READ_SEARCH` to read them; `--without-keys` skips them.
- Jarl raises a zone's serial above the one named has loaded whenever it
  writes a zone file whose serial isn't higher (after restoring an older
  database, say), so named loads it (it refuses otherwise for a signed
  zone) and secondaries pick it up.
- Two-factor login to the web UI with an authenticator app (TOTP: SHA-1,
  6 digits, 30 s, as every app supports). Users turn it on under Account
  (password, QR code, a code to confirm) and get 10 one-time recovery
  codes. Logging in then asks for a code (or a recovery code) after the
  password; each code works once. In a session with two-factor login,
  creating or rotating API tokens, changing users and resetting someone's
  two-factor login need a code from the last 5 minutes: the web UI asks
  for one, API clients send `X-Jarl-TOTP`. API tokens and the local socket
  are not affected.
- `totp.require` in jarl.yaml (`none`, `admins`, `all`) makes two-factor
  login compulsory; such a user who hasn't set it up can only set it up
  after logging in. `totp.issuer` names the server in authenticator apps
  (default `Jarl <hostname>`).
- Resetting a user's two-factor login (lost phone): Users → Reset 2FA,
  `jarl user totp reset NAME`, or on the server
  `jarld user totp reset NAME` (also with jarld stopped).
- The dashboard and `jarl status` list users who must use two-factor login
  but haven't set it up, and suggest disabling the first `admin` account
  when it is still active next to personal administrator accounts.
  `jarl user list`/`show` and the Users page show who uses it.
- API: `POST /auth/login/totp`, `/me/totp` (`setup`, `enable`, `disable`,
  `recovery-codes`), `DELETE /users/{id}/totp`; database migration 4.
- `scripts/testenv.sh`: turns a fresh Debian/Ubuntu machine into a test bed.
  It installs BIND and the build tools (Go from go.dev), writes a hand-made
  style configuration with internal and external views, a split-horizon
  zone (`example.com` or `JARL_TEST_ZONE`) and a reverse zone, starts named
  and prints the steps to install Jarl and adopt the configuration
  (docs/development.md).
- View colours. Give a view a colour (Views → Edit, `jarl view color`, or
  `PUT /views/{id}/color`) and the zone list, the zone page and the views
  list show its name in that colour. The colours are muted, and pastel in
  dark mode. The default is the link colour. A colour isn't configuration,
  so setting one needs no changeset or deploy.
- A "← Zones" link above a zone, back to the zone list, and "← History"
  above a changeset. The zone list keeps its filter, view and type in the
  address, so going back to it (with that link or the browser's back
  button) restores them. A view opened from a zone or the zone list has a
  "← example.com (external)" or "← Zones" link back.

### Changed

- The version moved from the header to a footer: "Powered by Jarl v0.1.0",
  linking to the release on Gitea. A build that isn't of a release tag
  shows its commit instead, linked to the commit and marked `-modified`
  with uncommitted changes. Before, every build of a commit after a
  release still showed the release's version. `GET /status` and
  `/auth/whoami` report the build as `build` (docs/development.md).
- `jarld version`, `jarl --version`, `jarl status` and `jarl whoami` give
  a version number only for release builds. Other builds say they are
  development builds and how far past the last tag they are: `dev
  ca0f148b78b6 (3 commits after v0.2.0-rc.1)`. Before, they printed the
  version and the commit (`0.2.0-rc.1 (ca0f148b78b6)`), which read like a
  release.
- `make deb` gives development builds their own package version after
  the last tag (`0.2.0~rc.1+git3.gca0f148`, plus the build time with
  uncommitted changes). Installing one over the RC or an older build is
  an upgrade: no more `apt install --reinstall`. It also removes older
  packages from `dist/` (docs/development.md).
- The view in the zone list, and on the zone page, links to that view,
  and the views page highlights it. It used to be plain text, and the zone
  page linked to the views page as a whole.
- The zone's Name servers tab shows at once and follows the check as it
  happens. Each query is listed as a dig command line (`dig @192.0.2.1
  example.org. SOA +norec`) with a "waiting 1.8 s" counter until it is
  answered. The finished result then replaces the progress, and the queries
  stay under "Queries sent". Results, the delegation check's included, are
  kept for 10 minutes, so returning to the tab shows them at once; "Check
  again" asks anew. A check keeps running if you leave the tab. Behind it,
  `GET /zones/{zone}/serials?stream=1` streams the queries as
  newline-delimited JSON (docs/api.md).
- The delegation check streams its queries the same way, every one of
  them: finding the parent zone, its servers' addresses, the NS and DS
  queries to each parent server and the SOA from each delegated server.
  Each shows a short answer ("referral to katelyn.ns.cloudflare.com., …",
  "DS 2371", "NXDOMAIN"). The serials check now lists its address lookups
  as separate A and AAAA queries. `GET /zones/{zone}/delegation?stream=1`
  streams them.
- Switching a zone's tabs (Records, Settings, …) no longer blanks the page
  while the tab loads: the page changes once the tab is ready, and
  "Loading…" appears only if a page takes a while.
- `jarl zone serials` compares the serial named serves, which for a signed
  zone is the signed zone's (ahead of Jarl's).
- `jarld import` turns `dnssec-policy` in an existing configuration into
  the zones' DNSSEC setting, and warns that their keys must be moved into
  Jarl's key directory before adopting.
- `dnssec-policy` is no longer accepted as a zone, view or server option
  (zones have a DNSSEC setting instead), nor `key-directory` as a zone
  option.
- Deleting a zone also removes the journal and signed files named kept
  next to it.
- Release candidates (tags like `v0.2.0-rc.1`) publish their `.deb`s to a
  separate `testing` distribution of the package registry instead of
  `stable`. Servers that follow `stable` can't pick up an RC with
  `apt upgrade`. An RC may also take its release notes from the
  `## [0.2.0]` or `## [Unreleased]` section of the CHANGELOG instead of
  needing its own (docs/development.md, "Release candidates").

### Fixed

- Publishing a release candidate failed: `scripts/gitea-release.sh`
  rejected its `.deb`s, whose names carry the Debian version
  (`0.2.0~rc.1`) instead of `0.2.0-rc.1`.
- `jarld init -u` and the install guide recommend naming the first
  administrator after yourself (one account per person).
- `jarld import` no longer warns that a zone with `allow-update { none; }`
  uses dynamic updates (validation already allowed it).
- docs/cli.md gives the CLI configuration file's location on macOS
  (`~/Library/Application Support/jarl/config.yaml`) and Windows
  (`%AppData%\jarl\config.yaml`). It was documented only as
  `~/.config/jarl/config.yaml`.

## [0.1.0] - 2026-10-09

The first version.

### Added

- Daily database backups: the `jarl-backup.timer` systemd timer (turned on
  by the Debian package) runs `jarld backup`, which writes
  `jarl-<UTC time>.db` into `backup.dir` (`/var/backups/jarl`), checks it
  with SQLite's integrity check before giving it that name, and deletes
  backups older than `backup.retention` (30d) while always keeping the
  newest `backup.keep_at_least` (7). Ages come from the names, and only
  files named like backups are ever deleted. Settings are in the new
  `backup:` section of jarl.yaml; the schedule is the timer's. The dashboard
  and `jarl status` show the newest backup, and warn when it is older than
  `backup.warn_after` (2d) or the last attempt failed. `backup.stats` also
  backs up the statistics database.
- `jarld restore [FILE | latest]`: lists backups, or checks one, shows what
  it holds next to the current database, and after confirmation replaces
  the database with it, keeping the current one as
  `jarl.db.before-restore-<time>`. It refuses while jarld runs: `jarld
  serve` now holds a lock (`jarl.db.lock`), which also stops two jarlds from
  using the same database. docs/operations.md explains restoring.
- Warnings before API tokens expire, from 14 days ahead: on the dashboard,
  in token lists ("soon", "expired"), once a day in jarld's log, and from
  the `jarl` CLI on stderr whenever it uses such a token (responses carry a
  `Jarl-Token-Expires` header). `jarl token list --expiring [WITHIN]` lists
  them.
- `jarl zone serials ZONE` and the zone page's Name servers tab: ask the
  zone's other name servers which serial they serve (a primary zone's NS
  records and also-notify targets, a secondary zone's primaries, with their
  ports and TSIG keys) and compare it with this server's. Exits with 2 when
  one is behind or doesn't answer.
- `jarl zone delegation ZONE` and a button on the Name servers tab: for
  zones on the internet, checks that the parent zone delegates the zone to
  the name servers in its NS records, with matching glue, and that each of
  them serves it. An undelegated (internal-only) zone gets one calm note.
  Neither check runs unless asked.
- jarld sends `Server: Jarl/<version>`.
- CLI exit code 2: a check ran and found problems.
- CLI: several servers in one configuration file. Name them
  (`jarl config server add ns1 URL`), pick one with `-s/--server NAME` or
  `JARL_SERVER`, set a default with `jarl config use`, and group them
  (`jarl config group set dns ns1 ns2`). A command aimed at a group (or
  `all`) is first checked on every server as a dry run and only runs if it
  succeeds everywhere, so a change one server rejects changes nothing
  anywhere. Named servers always use their own token.
- Reverse zones for any network: a /32 (or /128) gets a zone that answers
  for just that address, and a network between octet (or nibble)
  boundaries, such as a /22, is covered by several zones (four /24s) that
  are created together, from the CLI (`jarl zone create 10.0.8.0/22`) and
  the web UI. Networks smaller than a /24 explain that they belong in the
  enclosing /24's zone.
- docs/operations.md: setting up a secondary server with its own jarld.
- A local unix socket, `/run/jarl/jarl.sock` (`socket` in jarl.yaml).
  Requests on it from root or jarld's own user need no token and act as
  an administrator (the kernel's `SO_PEERCRED` says who is connecting);
  anyone else must send a token. The `jarl` CLI uses it when no server is
  configured, or with `-s local`, so `sudo jarl status` works on the
  server with nothing set up, and losing every token or password never
  locks root out. Changes are audited under the system user's name via
  `socket`. The systemd unit creates `/run/jarl` (0750).
- Jarl is released under the MIT License (`LICENSE`), which is installed
  with the docs and is the Debian package's `copyright` file.
- Debian packages: `make deb` builds, with only `dpkg-deb` (no root) and
  for the host or any other architecture (`DEB_ARCH=arm64`), `jarl` (the
  server: jarld, its units and docs) and `jarl-cli` (the `jarl` CLI, its
  completion and the ACME hooks), which `jarl` depends on. `jarl-cli` has no
  scripts, so it can go on any machine you manage Jarl from. Installing
  `jarl` creates the `jarl` user and directories and an example
  `/etc/jarl/jarl.yaml`; upgrades restart a running jarld and never touch
  `/etc/jarl/jarl.yaml`; removing it stops jarld, and even a purge keeps
  Jarl's database and the files named uses.
- Releases from Gitea Actions: pushing a `v<version>` tag runs
  `.gitea/workflows/release.yml`, which tests, builds and publishes a Gitea
  release (the CHANGELOG section as notes; the tarballs, the CLI for Linux,
  macOS and Windows, the `.deb`s and `SHA256SUMS`), and uploads the `.deb`s
  for amd64 and arm64 to the Gitea Debian registry, so servers install and
  upgrade Jarl with apt. `make cli-dist` builds the standalone CLI files;
  `scripts/gitea-release.sh` publishes. docs/development.md has the setup
  (a runner and a `RELEASE_TOKEN` secret), docs/install.md the apt source.
- Bash completion for `jarl` and `jarld`, installed by `make install` and
  the Debian package. Besides commands and flags, it completes server and
  group names from the CLI configuration, zone, view, ACL, TSIG key and
  user names from the server, and record types.
- `make dist` tarballs include the completion scripts (`completion/`).
- Token rotation: `jarl token rotate`, the Rotate button in the web UI and
  `POST /api/v1/tokens/{id}/rotate` give a token a new secret while it
  keeps its ID, name, user and grants. The old secret stops at once or after
  a grace period of up to 7 days (`--grace`), during which jarld logs who
  still uses it. A token that expires gets its lifetime again. `--save`
  writes the new secret where the CLI got the old one (its configuration or
  `--token @FILE`), `--write FILE` to any file, and `--current` picks the
  token the CLI runs with, so a restricted token can renew itself.
  `jarl token list` shows when a token was last rotated.
- An endpoint for lego's `httpreq` DNS provider
  (`/api/v1/acme/httpreq/present` and `/cleanup`), so lego and Traefik can
  publish DNS-01 challenges with only environment variables, without the
  jarl CLI. lego's username and API token arrive as HTTP Basic auth, which
  is accepted on these routes only. Off by default
  (`acme.httpreq.enabled`), and HTTPS-only by default: jarld's own TLS, or a
  trusted proxy that says so with `X-Forwarded-Proto` or `Forwarded`.
  Plain HTTP can be allowed from loopback only (`allow_loopback_http`) or
  everywhere (`require_https: false`). `GET /api/v1/acme/httpreq` shows how
  jarld sees a request, to check a proxy setup. `jarl acme` and the endpoint
  share their code (`internal/acme`).
- Trusted proxies may also send the standard `Forwarded: proto=https`
  header. When a proxy header lists several values, the last one (added by
  the nearest proxy) counts.
- lego support: `contrib/lego/jarl-lego.sh` is a program for lego's `exec`
  DNS provider that publishes DNS-01 challenges through `jarl acme`,
  including challenge names reached through a CNAME (docs/acme.md).
- docs/concepts.md: what each zone type does, what to enter as a new zone's
  name servers (and when glue addresses are needed), how reverse zones map
  to networks, and why dynamic updates give way to API tokens.

- A logo: a bearded Viking jarl in blue and white, whose crown holds a DNS
  tree (a root node and its branches). The master is `artwork/logo.png`;
  `scripts/logo.py` traces it into vector paths (`assets/logo.svg`, 6 KB,
  and `assets/logo.js`). It is shown on the login page, links home in the
  top left of the web UI, and is the favicon. The UI draws it inline, so it
  appears together with the page.
- The login page shows an angular, Norse-style "JARL" wordmark drawn as
  SVG paths (`assets/brand.js`) above a rule with a "DNS" node; it follows
  the light and dark themes. The header beside the logo shows the same
  letters, without the rule, so the UI needs no web font.
- The README opens with the login page's banner, the logo above the
  wordmark (`artwork/banner.svg`, built by `scripts/banner.py` from the web
  UI's own logo and wordmark, with light and dark colors).

- Web UI: wherever an address match list is entered (server, view and zone
  options such as allow-query or allow-transfer, view match lists, ACL
  elements) the existing ACLs, TSIG keys and built-in names are offered as
  one-click suggestions, and names that don't exist are flagged as you type.

- **Query statistics** (off by default; `stats` in jarl.yaml, docs/stats.md).
  When enabled, Jarl adds a loopback statistics channel and a response log to
  named's configuration (merged into existing `logging` and
  `statistics-channels` statements) and switches response logging with
  `rndc responselog`. jarld aggregates named's counters and the log into a
  separate SQLite database: per-minute, hourly and daily counters (queries,
  result codes, record types, views, zones, cache hits, upstream latency,
  DNSSEC) and hourly and daily top lists (names, clients, NXDOMAIN and
  SERVFAIL names, refused clients), each with its own retention. Clients can
  be anonymized or excluded. It is shown on a new Statistics page in the web
  UI (KPI tiles, queries and failed answers over time, a weekday x hour
  heatmap, top lists and breakdowns, each chart with a table view), in
  `jarl stats status|summary|top|timeline|heatmap|breakdown`, and in the API
  under `/api/v1/stats/`, behind the new `stats` permission. Works with the
  bind9 packages of Debian 13 and Ubuntu 26.04.
- At startup jarld brings named's configuration up to date with jarl.yaml
  settings that affect it (such as statistics), through the usual checked
  pipeline. Files changed by hand are never overwritten.
- **jarld daemon**: REST API (`/api/v1`) and embedded web UI, with SQLite as
  the source of truth for the whole BIND configuration. Runs under systemd
  (`Type=notify`, sandboxed, unprivileged `jarl` user in group `bind`).
  SIGHUP and certificate file changes reload TLS.
- **Configuration model**: views (ordered, match-clients/destinations,
  recursive-only), ACLs (nested, negation, keys, reference tracking with
  rename and delete protection), TSIG keys (kept in a separate `keys.conf`,
  never in diffs), zones of every type (primary, secondary, stub,
  static-stub, forward, mirror, hint, redirect, in-view), reverse zones
  from a CIDR, records of every type, options at server, view, zone and
  top-level scope, and defaults for new zones.
- **BIND 9.20 option catalog**: all 353 statements with grammar, allowed
  scopes, value kinds, deprecation status and ARM descriptions, used for
  validation and by the UI's option editor.
- **Changesets**: immediate one-operation changes by default; staging into
  named changesets (`?changeset=`, `X-Jarl-Changeset`, `--changeset`),
  batches (`POST /apply`, `jarl apply -f`), dry runs, previews with diffs,
  and revert of applied changesets. Optimistic locking with object versions.
- **Apply pipeline**: whole-configuration validation, rendering, `named-checkconf -z`
  and `named-checkzone` in a staging directory, atomic install, `rndc reconfig`
  and per-zone reload, verification with `rndc zonestatus`, and automatic
  rollback when named doesn't load the change. Automatic serials (date,
  increment or unixtime policy, RFC 1982), bumped only when DNS data
  changes. Drift detection for files changed outside Jarl.
- **Validation**: CNAME/DNAME rules, NS/MX/SRV targets, glue and
  delegations, RRset TTL consistency, BIND 9.20 RRset/type limits, SPF/DMARC
  sanity, ACL/key references and cycles, option syntax and scope, and
  security lints (open resolver, open zone transfers, dynamic updates on
  managed zones).
- **Records**: TXT entered as plain text (automatic quoting and 255-byte
  splitting), relative and absolute names with detection of doubled
  origins, PTR records kept in step with A/AAAA (`ptr`), RRset replace,
  delete by match, zone file import (merge or replace).
- **Import and adoption**: `jarld import` reads an existing named.conf tree
  and zone files (comments, `$INCLUDE`, `$GENERATE`, legacy
  `master`/`slave` spellings); `jarld adopt` switches named to Jarl's
  configuration with a backup and automatic fallback.
- **Authentication**: web logins with argon2id passwords, sessions
  (HttpOnly, SameSite=Strict) and CSRF tokens, rate limiting per user and
  IP; hashed API tokens (`jarl_...`) with optional expiry.
- **Permissions**: granular grants (resource × read/write, filtered by zone,
  view, record name pattern and type), roles (`readonly`, `dns-editor`,
  `operator`, `acme`), tokens restricted to a subset of their user's
  rights, administrators.
- **Audit log** of logins, changes, users, tokens and secret reveals, with
  user, token, IP and outcome, searchable and written to the journal.
- **Web UI**: dashboard, zones and records with inline editing and pending
  markers, views, ACLs, TSIG keys, the option editor, review and apply,
  history with revert, audit log, users, account and tokens, search.
  Review mode by default, with an "apply immediately" switch.
- **jarl CLI**: zones, records, views, ACLs, TSIG keys, options, settings,
  changesets, batches, history, users, tokens, audit, search, status, check
  and resync. Table, JSON and YAML output, and documented exit codes.
- **ACME DNS-01**: `jarl acme set|unset`, certbot hooks
  (`jarl acme certbot-auth|certbot-cleanup`), an acme.sh DNS API hook
  (`contrib/acme.sh/dns_jarl.sh`), automatic zone and view discovery,
  idempotent retries, and `--follow-cname` / `--resolver` for a dedicated
  ACME zone.
- **Operations**: `jarld backup` (online), `jarld resync`, `jarld check`,
  `jarld render`, local user recovery commands, audit retention.
- **Packaging**: Makefile (build, test, e2e, install, dist), systemd unit,
  sysusers.d and tmpfiles.d files, example configuration
  (`jarld config --example`).
- **Tests**: unit tests for every package, integration tests against the
  real named 9.20 (checkers, reload and rollback, import and adopt), and an
  end-to-end script (`scripts/e2e.sh`) that drives every CLI command
  against a running named.
- **Documentation**: concepts, install and adoption, configuration, CLI,
  API, permissions, ACME, validation, operations and development guides, and
  a split-DNS guide for adding views to a server that has none.

### Changed

- Web UI: the review/live switch is a small "Review edits" / "Live edits"
  button in the header, and the bar below it only appears while there are
  pending changes.
- TSIG keys: the name help no longer calls `xfer-key` a domain name (any
  letters, digits, hyphens and dots will do; both servers must use the same
  name), and the keys page points to restricted API tokens for giving
  scripts or people limited access to zones and records.
- Web UI, new zone dialog: choose **Domain** or **Reverse zone**. For a
  reverse zone you give the network (10.10.0.0/24, 2001:db8:1::/48) and the
  zone name is generated. Either way the dialog shows the exact zone name it
  will create and explains problems before submitting: an address or URL
  instead of a name, a host-like name such as www.example.com, a zone that
  already exists in the view, a child or parent of an existing zone, and
  networks that don't follow the octet or nibble boundaries.
- Web UI, record form: after adding a record every field is cleared except
  the type, and the cursor returns to the name. A "Will add:" line shows the
  record exactly as it will be stored, with warnings for unqualified names
  (e.g. a CNAME to readthedocs.io without the final dot). In reverse zones
  the form asks for the address, defaults to PTR, offers the host names of
  A/AAAA records with that address, warns about a second PTR for an
  address, and the record list shows each record's address.
- Reverse zones: a record name can be given as an address (10.10.0.20) in
  the API and CLI too, and a PTR target without a final dot that contains a
  dot (nas.adbraun.lol) is read as the full host name (with a warning); a
  bare label is refused.

- `jarl resync` / `jarld resync` refuse to overwrite files that were changed
  outside Jarl unless `--force` is given, as documented. Before, they always
  overwrote them.

### Fixed

- The logo popped in after the page: it was an 880 KB SVG wrapping a
  1254-pixel PNG, downloaded in full on every page load. It is now traced
  into 6 KB of vector paths and drawn inline. Static files also get an ETag,
  so reloads revalidate them with 304 answers instead of downloading them
  again.
- `jarl token create --save` stored the token at the top level of the
  CLI configuration even when a named server was selected; it now goes into
  that server's entry.
- The web UI showed future times, such as token expiry dates, as "just
  now"; they now read "in 29 days".
- The dashboard's "Pending changes (1 open)" counted empty changesets (and
  other users'), so the Changes page then showed none. It now counts your
  own changesets that contain changes, and the status API's
  `open_changesets` only counts non-empty ones. In review mode, a draft
  created for an edit that the server rejects is discarded instead of
  being left open and empty.
- Under the shipped systemd unit (`RestrictSUIDSGID=yes`), the first zone
  in a new view failed with "chmod /var/lib/bind/jarl/VIEW: operation not
  permitted": setting the setgid bit on the new directory is refused there.
  Jarl now falls back to the permission bits, so the directory is
  group-writable for named, and only changes the mode when it needs to.
- Web UI: the "Jarl 0.1.0" brand link no longer underlines the gap between
  the name and the version on hover.
- Web UI: creating a zone from the dashboard's "New zone" link no longer
  opens the dialog a second time.
- Warnings noticed while parsing record data (a name read as absolute) were
  lost before reaching the result; they are shown again.

- The negative-caching warning now uses the effective negative TTL, which
  is the smaller of the SOA minimum and the zone's default TTL (RFC 2308).
  It explains the real effect (new names can stay invisible to resolvers
  that already asked) and gives the command that fixes it. Before, it
  fired on the SOA minimum alone and wrongly blamed BIND's resolver cap.
- Problems printed by `jarld check` show zone names without the trailing dot.
- `jarl` now shows the warnings a change introduces when it is applied or
  staged, not only on dry runs.
- `jarl check` and `jarl resync` no longer print named-checkconf's routine
  "loaded serial" lines, only its errors and warnings.
- `jarl zone list` showed only primary zones: `zone create`'s default
  `--type primary` leaked into the list filter through a shared variable.
  Hint, secondary, forward and other zones are listed again.
- named-checkconf and named-checkzone output is classified by the tools'
  exit code. Their warnings (e.g. `both "recursion no;" and "allow-recursion"
  active`) were shown as errors. They are now shown as warnings in the
  CLI, `jarld check` and the web UI.
- The `zone_outside_view` error says how to fix it (`--adopt-zones`).
- The end-to-end test starts named with `-f` like the Debian unit; with `-g`,
  named sends all logging to stderr.
