**Notice for Windows users:** We are aware of an issue with the installer
failing to download the dictionaries used for spellchecking. We are currently
working on a fix and hope to have this resolved as soon as possible.
We've released another bug fix version of Pidgin, version 2.14.8. This
release only has a few random bug fixes, but it does fix a regression that was
causing some timestamp issues at least with the Discord plugin.
You can find links to the download from our
[Install page]({{< ref "/install" >}}).
