@@ -327,3 +327,18 @@ Bug fixes:
  - Fixed an issue where 4-bit serialization would fail for layers without double quantization #868. Thank you, @poedator
  - Fixed an issue where calling .to() or .cuda() on a 4-bit layer twice would result in an error #867. Thank you, @jph00
 
+### 0.42.0

+Features:
+ - 4-bit serialization now supported. This enables 4-bit load/store. Thank you @poedator #753
+ - the bitsandbytes library now has a version attribute: `bitsandbytes.__version__` @rasbt #710
+
+Bug fixes:
+ - Fixed bugs in dynamic exponent data type creation. Thank you @RossM, @KohakuBlueleaf, @ArrowM #659 #227 #262 #152
+ - Fixed an issue where 4-bit serialization would fail for layers without double quantization #868. Thank you, @poedator
+ - Fixed an issue where calling .to() or .cuda() on a 4-bit layer twice would result in an error #867. Thank you, @jph00
+ - Fixed a bug where a missing access permission in a path searched for CUDA would lead to an error @osma #677
+ - Fixed a bug where the GOOGLE_VM_CONFIG_LOCK_FILE variable could cause errors in colab environments @akrentsel @xaptronic #715 #883 #622
+ - Fixed a bug where kgetColRowStats (LLM.int8()) would fail for certain dimensions @LucQueen @905
