 # Changelog
 
+## `v10.0.0`
+
+This release improves on `9.1.0` in many aspect, including general fixes, Fail2Ban, LDAP and documentation. This release contains breaking changes.
+
+- **[general]** Fixed many prose errors (spelling, grammar, indentation).
+- **[general]** Documentation is better integrated into the development process and it's visibility within the project increased ([#1878](https://github.com/docker-mailserver/docker-mailserver/pull/1878)).
+- **[general]** Added `stop_grace_period:` to example Compose file and supervisord ([#1896](https://github.com/docker-mailserver/docker-mailserver/pull/1896) [#1945](https://github.com/docker-mailserver/docker-mailserver/pull/1945))
+- **[general]** `./setup.sh email list` was enhanced, now showing information neatly ([#1898](https://github.com/docker-mailserver/docker-mailserver/pull/1898))
+- **[general]** Added update check and notification ([#1976](https://github.com/docker-mailserver/docker-mailserver/pull/1976), [#1951](https://github.com/docker-mailserver/docker-mailserver/pull/1951))
+- **[general]** Moved environment variables to the documentation and improvements ([#1948](https://github.com/docker-mailserver/docker-mailserver/pull/1948), [#1947](https://github.com/docker-mailserver/docker-mailserver/pull/1947), [#1931](https://github.com/docker-mailserver/docker-mailserver/pull/1931))
+- **[security]** Major Fail2Ban improvements (cleanup, update and breaking changes, see below)
+- **[fix]** `./setup.sh email del ...` now works properly 
+- **[code]** Added color variables to `setup.sh` and improved the script as a whole ([#1879](https://github.com/docker-mailserver/docker-mailserver/pull/1879), [#1886](https://github.com/docker-mailserver/docker-mailserver/pull/1886))
+- **[ldap]** Added `LDAP_QUERY_FILTER_SENDERS` ([#1902](https://github.com/docker-mailserver/docker-mailserver/pull/1902))
+- **[ldap]** Use dovecots LDAP `uris` connect option instead of `hosts` ([#1901](https://github.com/docker-mailserver/docker-mailserver/pull/1901))
+- **[ldap]** Complete rework of LDAP documentation ([#1921](https://github.com/docker-mailserver/docker-mailserver/pull/1921))
+- **[docs]** PRs that contain changes to docs will now be commented with a preview link ([#1988](https://github.com/docker-mailserver/docker-mailserver/pull/1988))
+
+### Breaking Changes
+
+- **[security]** Fail2Ban adjustments:
+  - Fail2ban v0.11.2 is now used ([#1965](https://github.com/docker-mailserver/docker-mailserver/pull/1965)).
+  - The previous F2B config (from an old Debian release) has been replaced with the latest default config for F2B shipped by Debian 10.
+  - The new default blocktype is now `DROP`, not `REJECT` ([#1914](https://github.com/docker-mailserver/docker-mailserver/pull/1914)).
+  - A ban now applies to all ports (`iptables-allports`), not just the ones that were "attacked" ([#1914](https://github.com/docker-mailserver/docker-mailserver/pull/1914)).
+  - Fail2ban 0.11 is totally compatible to 0.10, but the database got some new tables and fields (auto-converted during the first start), so once updated to DMS 10.0.0, you have to remove the database `mailstate:/lib-fail2ban/fail2ban.sqlite3` if you would need to downgrade to DMS 9.1.0 for some reason.
+- **[ldap]** Removed `SASLAUTHD_LDAP_SSL`. Instead provide a protocol in `SASLAUTHD_LDAP_SERVER` and adjust `SASLAUTHD_LDAP_` default values ([#1989](https://github.com/docker-mailserver/docker-mailserver/pull/1989)).
+- **[general]** Removed `stable` release tag ([#1975](https://github.com/docker-mailserver/docker-mailserver/pull/1975)):
+  - Scheduled builds are now based off `edge`.
+  - Instead of `stable`, please use the latest version tag available (_or the `latest` tag_).
+  - The `stable` image tag will be removed from DockerHub in the near future.
+- **[setup]** Removed `./setup config ssl` command (_deprecated since v9_). `SSL_TYPE=self-signed` remains supported however. ([`dc8f49de`](https://github.com/docker-mailserver/docker-mailserver/commit/dc8f49de548e2c2e2aa321841585153a99cd3858), [#2021](https://github.com/docker-mailserver/docker-mailserver/pull/2021))
+
 ## `v9.1.0`
 
 This release marks the breakpoint where the wiki was transferred to a [reworked documentation](https://docker-mailserver.github.io/docker-mailserver/edge/)
