+
+### Features
+
+* [Core]
+  * Adding the ContextFilterPlugin ([a06bf27](https://github.com/google/adk-python/commit/a06bf278cbc89f521c187ed51b032d82ffdafe2d))
+  * Adds plugin to save artifacts for issue [#2176](https://github.com/google/adk-python/issues/2176) ([657369c](https://github.com/google/adk-python/commit/657369cffe142ef3745cd5950d0d24a49f42f7fd))
+  * Expose log probs of candidates in LlmResponse ([f7bd3c1](https://github.com/google/adk-python/commit/f7bd3c111c211e880d7c1954dd4508b952704c68))
+* [Context Caching]
+  * Support context caching ([c66245a](https://github.com/google/adk-python/commit/c66245a3b80192c16cb67ee3194f82c9a7c901e5))
+    - Support explicit context caching auto creation and lifecycle management.
+
+      Usage: `App(root_agent=..., plugins=..., context_cache_config=...)`
+  * Support non-text content in static instruction ([61213ce](https://github.com/google/adk-python/commit/61213ce4d4c10f7ecaf6ddb521672059cee27942))
+  * Support static instructions ([9be9cc2](https://github.com/google/adk-python/commit/9be9cc2feee92241fd2fbf9dea3a42de5a78e9ce))
+    - Support static instruction that won't change, put at the beginning of
+      the instruction.
+      Static instruction support inline_data and file_data as contents.
+      Dynamic instruction moved to the end of LlmRequest, increasing prefix
+      caching matching size.
+
+      Usage:
+      `LlmAgent(model=...,static_instruction =types.Content(parts=...), ... )`
+* [Telemetry]
