Tapbots released Tweetbot 2.4.2, adding compatibility with macOS 10.12 Sierra and support for extended tweets, where photos, videos, GIFs, and quote tweets no longer count toward Twitter’s 140-character limit. The update also adds support for uploading videos up to 140 seconds long to Twitter and improves media previews for search results. Shortly after this release, Tapbots issued Tweetbot 2.4.3 with a fix for a corrupted image cache. ($9.99 new from the Mac App Store, free update, 11.7 MB, 10.10+)
