             "The app no longer crawls a 21,000-server directory in the background on every launch. It now loads that list the first time you open the connector browser, and not before.",

             "The model you pick is the model that runs. The retired free tier was quietly forcing every session onto Haiku no matter what the picker said; it is gone, and installs still carrying it are moved off.",
+            "Apps with their own backend can start it again. On packaged builds the bundled Python shipped without the piece that makes a virtual environment usable, so every new app's backend died on startup while three separate steps reported success.",
+            "An app whose backend is switched on always boots a real server now, instead of being served as a prebuilt page wired to an API that was never started.",

+            "A question the assistant asks from a collapsed chat is wide enough to read, instead of being cut off at the right edge.",
             "Fable is no longer offered in the model picker. It never worked when selected.",
             "A chat that started failing on \"that request hit a snag\" now recovers on your next message instead of staying broken until you branch it.",
             "Apps no longer get stuck on \"Starting preview\" forever; one app serving a prebuilt bundle used to silently wedge every other app until a restart.",
