 NOTE: Add new changes BELOW THIS COMMENT.
 -->

+### Added
+
+- Etc timezones to the timezone list ([#6568]).
+- The schema version of the configuration file to the output of running
+  `AdGuardHome` (or `AdGuardHome.exe) with `-v --version` command-line options
+  ([#6545]).
+- Ability to disable plain-DNS serving via UI if an encrypted protocol is
+  already used ([#1660]).
+
 ### Changed

- "Block" and "Unblock" buttons of the query log moved to the tooltip menu ([#684]).
+- The bootstrapped upstream addresses now updated according to the TTL of the
+  bootstrap DNS response ([#6321]).
+- Logging level of timeout errors is now `error` instead of `debug` ([#6574]).
+- The field `"upstream_mode"` in `POST /control/dns_config` and
+  `GET /control/dns_info` HTTP APIs now accepts `load_balance` value.  Check
+  `openapi/CHANGELOG.md` for more details.
+
+#### Configuration changes
+
+In this release, the schema version has changed from 27 to 28.
+
+- The new property `clients.persistent.*.uid`, which is unique identifier of the
+  persistent client.
+- The properties `dns.all_servers` and `dns.fastest_addr` were removed, their
+  values migrated to newly added field `dns.upstream_mode` that describes the
+  logic through which upstreams will be used.  See also a [Wiki
+  page][wiki-config].
+
+  ```yaml
+  # BEFORE:
+  'dns':
+      # …
+      'all_servers': true
+      'fastest_addr': true
+
+  # AFTER:
+  'dns':
+      # …
+      'upstream_mode': 'parallel'
+  ```
+
+  To rollback this change, remove the new field `upstream_mode`, set back
+  `dns.all_servers` and `dns.fastest_addr` properties in `dns` section, and
+  change the `schema_version` back to `27`.
+
+### Fixed
+
+- Panic on using `--no-etc-hosts` flag ([#6644]).
+- Schedule display in the client settings after creating or updating.
+- Zero value in `querylog.size_memory` disables logging ([#6570]).
+- Non-anonymized IP addresses on the dashboard ([#6584]).
+- Maximum cache TTL requirement when editing minimum cache TTL in the Web UI
+  ([#6409]).
+- Load balancing algorithm stuck on a single server ([#6480]).
+- Statistics for 7 days displayed as 168 hours on the dashboard.
+- Pre-filling the Edit static lease window with data ([#6534]).
+- Names defined in the `/etc/hosts` for a single address family wrongly
+  considered undefined for another family ([#6541]).
+- Omitted CNAME records in safe search results, which can cause YouTube to not
+  work on iOS ([#6352]).

+ #  Contributing to AdGuard Home
+
+If you want to contribute to AdGuard Home by filing or commenting on an issue or
+opening a pull request, please follow the instructions below.
+
+
+
+##  General recommendations
+
+Please don't:
+
+ *  post comments like “+1” or “this”.  Use the :+1: reaction on the issue
+    instead, as this allows us to actually see the level of support for issues.
+
+ *  file issues about localization errors or send localization updates as PRs.
+    We're using [CrowdIn] to manage our translations and we generally update
+    them before each Beta and Release build.  You can learn more about
+    translating AdGuard products [in our Knowledge Base][kb-trans].
+
+ *  file issues about a particular filtering-rule list misbehaving.  These are
+    tracked through the [separate form for filtering issues][form].
+
+ *  send updates to filtering-rule lists, such as the ones for the Blocked
+    Services feature or the list of approved filtering-rule lists.  We update
+    them once before each Beta and Release build.
+
+Please do:
+
+ *  follow the template instructions and provide data for reproducing issues.
+
+ *  write the title of your issue or pull request in English.  Any language is
+    fine in the body, but it is important to keep the title in English to make
+    it easier for people and bots to look up duplicated issues.

+
+##  Issues
+
+   ###  Search first
+
+Please make sure that the issue is not a duplicate or a question.  If it's a
+duplicate, please react to the original issue with a thumbs up.  If it's a
+question, please look through our [Wiki] and, if you haven't found the answer,
+post it to the GitHub [Discussions] page.
+
+[Discussions]: https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a
+[Wiki]:        https://github.com/AdguardTeam/AdGuardHome/wiki
+
+
+
+   ###  Follow the issue template
+
+Developers need to be able to reproduce the faulty behavior in order to fix an
+issue, so please make sure that you follow the instructions in the issue
+template carefully.
+
+
+
+##  Pull requests
+
+   ###  Discuss your changes first
+
+Please discuss your changes by opening an issue.  The maintainers should
+evaluate your proposal, and it's generally better if that's done before any code
+is written.
+
+
+
+   ###  Review your changes for style
+
+We have a set of [code guidelines][hacking] that we expect the code to follow.
+Please make sure you follow it.
+
+[hacking]: https://github.com/AdguardTeam/CodeGuidelines/blob/master/Go/Go.md
+
+
+
+   ###  Test your changes
+
+Make sure that it passes linters and tests by running the corresponding Make
+targets.  For backend changes, it's `make go-check`.  For frontend, run
+`make js-lint`.
+
+Additionally, a manual test is often required.  While we're constantly working
+on improving our test suites, they're still not as good as we'd like them to be.
