v2.13.0

We're pleased to be publishing v2.13.0, a new stable release. This is a bugfix release that fixes some issues, including a crash.

This release includes no changes to the config file format or database format.

Many thanks to @dallemon, @jwheare, @Mikaela, @nealey, and @Sheikah45 for contributing patches, reporting issues, and helping test.

Fixed

• Fixed a (hopefully rare) crash when persisting always-on client statuses (#2113, #2117, thanks @Sheikah45!)
• Fixed not being able to message channels with / (or the configured RELAYMSG separator) in their names (#2114, thanks @Mikaela!)
• Verification emails now always include a Message-ID header, improving compatibility with Gmail (#2108, #2110)
• Improved human-readable description of REDACT_FORBIDDEN (#2101, thanks @jwheare!)

Removed

• Removed numerics associated with the retired ACC spec (#2109, #2111, thanks @jwheare!)

Internal

• Upgraded the Docker base image from Alpine 3.13 to 3.19. The resulting images are incompatible with Docker 19.x and lower (all currently non-EOL Docker versions should be supported). (#2103)
• Official release builds use Go 1.21.6
