+# New features in CC: Tweaked 1.104.0
+
+* Update to Minecraft 1.19.4.
+* Turtles can now right click items "into" certain blocks (cauldrons and hives by default, configurable with the `computercraft:turtle_can_use` block tag).
+* Update Cobalt to 0.7:
+  * `table` methods and `ipairs` now use metamethods.
+  * Type errors now use the `__name` metatag.
+  * Coroutines no longer run on multiple threads.
+  * Timeout errors should be thrown more reliably.
+* `speaker` program now reports an error on common unsupported audio formats.
+* `multishell` now hides the implementation details of its terminal redirect from programs.
+* Use VBO monitor renderer by default.
+* Improve syntax errors when missing commas in tables, and on trailing commas in parameter lists.
+* Turtles can now hold flags.
+* Update several translations (Alessandro, chesiren, Erlend, RomanPlayer22).
+
+Several bug fixes:
+* `settings.load` now ignores malformed values created by editing the `.settings` file by hand.
+* Fix introduction dates on `os.cancelAlarm` and `os.cancelTimer` (MCJack123).
+* Fix the REPL syntax reporting crashing on valid parses.
+* Make writes to the ID file atomic.
+* Obey stack limits when transferring items with Fabric's APIs.
+* Ignore metatables in `textutils.serialize`.
+* Correctly recurse into NBT lists when computing the NBT hash (Lemmmy).
+* Fix advanced pocket computers rendering as greyscale.
+* Fix stack overflow when using `shell` as a hashbang program.
+* Fix websocket messages being empty when using a non-default compression settings.
+* Fix `gps.locate` returning `nan` when receiving a duplicate location (Wojbie).
+* Remove several thread safety issues inside Java-side argument parsing code.
