Version 62 (May 20, 2023)
-------------------------
Package updates:
* Nextcloud updated to 23.0.12 (and its apps also updated).
* Roundcube updated to 1.6.1.
* Z-Push to 2.7.0, which has compatibility for Ubuntu 22.04, so it works again.
Mail:
* Roundcube's password change page is now working again.
Control panel:
* Allow setting the backup location's S3 region name for non-AWS S3-compatible backup hosts.
* Control panel pages can be opened in a new tab/window and bookmarked and browser history navigation now works.

Version 61.1 (January 28, 2023)
-------------------------------

* Fix for TLS certificate SHA fingerprint not being displayed during setup.
Version 61 (January 21, 2023)
-----------------------------
System:
* fail2ban didn't start after setup.
Mail:
* Disable Roundcube password plugin since it was corrupting the user database.
Control panel:
* Fix changing existing backup settings when the rsync type is used.
* Allow setting a custom port for rsync backups.
* Fixes to DNS lookups during status checks when there are timeouts, enforce timeouts better.

* Fixed a color.
* Improve error messages in the management tools when external command-line tools are run.
Version 60.1 (October 30, 2022)
-------------------------------
* A setup issue where the DNS server nsd isn't running at the end of setup is (hopefully) fixed.
* Nextcloud is updated to 23.0.10 (contacts to 4.2.2, calendar to 3.5.1).
Version 60 (October 11, 2022)
-----------------------------
This is the first release for Ubuntu 22.04.
**Before upgrading**, you must **first upgrade your existing Ubuntu 18.04 box to Mail-in-a-Box v0.51 or later**, if you haven't already done so. That may not be possible after Ubuntu 18.04 reaches its end of life in April 2023, so please complete the upgrade well before then. (If you are not using Nextcloud's contacts or calendar, you can migrate to the latest version of Mail-in-a-Box from any previous version.)
For complete upgrade instructions, see:
https://discourse.mailinabox.email/t/version-60-for-ubuntu-22-04-is-about-to-be-released/9558
No major features of Mail-in-a-Box have changed in this release, although some minor fixes were made.
With the newer version of Ubuntu the following software packages we use are updated:
* dovecot is upgraded to 2.3.16, postfix to 3.6.4, opendmark to 1.4 (which adds ARC-Authentication-Results headers), and spampd to 2.53 (alleviating a mail delivery rate limiting bug).
* Nextcloud is upgraded to 23.0.4 (contacts to 4.2.0, calendar to 3.5.0).
* Roundcube is upgraded to 1.6.0.
* certbot is upgraded to 1.21 (via the Ubuntu repository instead of a PPA).
* fail2ban is upgraded to 0.11.2.
* nginx is upgraded to 1.18.
* PHP is upgraded from 7.2 to 8.0.
Also:
* Roundcube's login session cookie was tightened. Existing sessions may require a manual logout.
* Moved Postgrey's database under $STORAGE_ROOT.
Version 57a (June 19, 2022)

# When upgrading above versions, how to test?
#
# 1. Enter your server instance (or on the Vagrant image)
# 1. Git clone <your fork>
# 2. Git checkout <your fork>
# 3. Run `sudo ./setup/nextcloud.sh`
# 4. Ensure the installation completes. If any hashes mismatch, correct them.
# 5. Enter nextcloud web, run following tests:
# 5.1 You still can create, edit and delete contacts
# 5.2 You still can create, edit and delete calendar events
# 5.3 You still can create, edit and delete users
# 5.4 Go to Administration > Logs and ensure no new errors are shown
# Clear prior packages and install dependencies from apt.
