+## v0.1.13 (2023.4.16)
+
+1. Add openai audio adapter (**experimental**)
+
+```python
+cache.init(pre_embedding_func=get_file_bytes)
+
+openai.Audio.transcribe(
+    model="whisper-1",
+    file=audio_file
+)
+```
+
+2. Improve data eviction implementation
+
+In the future, users will have greater flexibility to customize eviction methods, such as by using Redis or Memcached. Currently, the default caching library is cachetools, which provides an in-memory cache. Other libraries are not currently supported, but may be added in the future.
+
+## v0.1.12 (2023.4.15)
