A new version of my favorite mail client Thunderbird has just been released on an Mozilla mirror ftp site
and will most likely be available on the website and by automatic updates
later this day.
If you can’t wait to get your hands on the latest version you could download
the latest Thunderbird release for Windows
The latest official version at this moment is version 188.8.131.52 and a lot of security
patches and bug fixes
have been implemented in this new version of Thunderbird.
According to the Rumbling Edge
there have been 21 changes in the latest version of Thunderbird. Most notably are fixed security issue and one crash issue.
The official release notes have not been updated yet to reflect the changes of this new release of Thunderbird.
It is most likely that they will be updated once the version will be officially announced on the Thunderbird homepage
and become available through the automatic update
option from within Thunderbird.
