Betterbird, a soft fork of Mozilla Thunderbird, has released version 128.8.0esr-bb23, which aims to address issues present in the earlier series 128. Fixes include eliminating the recurrence of messages in the POP inbox and improvements in message display settings. A new feature allows users to search for and install language packs more easily, with support for German, Dutch, French, Spanish, Italian, Portuguese, Polish, Ukrainian, Czech, Turkish, and Japanese. A portable version for Windows and an English Mac build are also available, with localization using Betterbird language packs.
