+We're pleased to be publishing v2.12.0, a new stable release. This is another bugfix release aimed at improving client compatibility and keeping up with the IRCv3 specification process.
 
 This release includes changes to the config file format, one of which is a compatibility break: if you were using `accounts.email-verification.blacklist-regexes`, you can restore the previous functionality by renaming `blacklist-regexes` to `address-blacklist` and setting the additional key `address-blacklist-syntax: regex`. See [default.yaml](https://github.com/ergochat/ergo/blob/e7597876d987a6fc061b768fcf878d0035d1c85a/default.yaml#L422-L424) for an example; for more details, see the "Changed" section below.

 ### Internal
 * Release builds are now statically linked by default. This should not affect normal chat operations, but may disrupt attempts to connect to external services (e.g. MTAs) that are configured using a hostname that relies on libc's name resolution behavior. To restore the old behavior, build from source with `CGO_ENABLED=1`. (#2023)
-* Upgraded to Go 1.21 (#2045, #2084)
+* Upgraded to Go 1.21 (#2045, #2084); official release builds use Go 1.21.3, which includes a fix for CVE-2023-44487
 * The default `make` target is now `build` (which builds an `ergo` binary in the working directory) instead of `install` (which builds and installs an `ergo` binary to `${GOPATH}/bin/ergo`). Take note if building from source, or testing Ergo in development! (#2047)
 * `make irctest` now depends on `make install`, in an attempt to ensure that irctest runs against the intended development version of Ergo (#2047)
