 # Changelog
 
+## [1.0.0-rc.2](https://github.com/google/adk-java/compare/v1.0.0-rc.1...v1.0.0-rc.2) (2026-03-27)
+
+
+### Features
+
+* add `InMemoryArtifactService` to `AgentExecutor` and update `pom.xml` dependencies ([24f8d5e](https://github.com/google/adk-java/commit/24f8d5e2562e1c0812ce6e248500797d9801fafd))
+* enabling output_schema and tools to coexist ([40ca6a7](https://github.com/google/adk-java/commit/40ca6a7c5163f711e02a54163d6066f7cd86e64d))
+
+
+### Bug Fixes
+
+* add media/image support in Spring AI MessageConverter ([8ab7f07](https://github.com/google/adk-java/commit/8ab7f072cdaa363e07b7a786044376c021c4c009)), closes [#705](https://github.com/google/adk-java/issues/705)
+* add schema validation to SetModelResponseTool (issue [#587](https://github.com/google/adk-java/issues/587) already implemented, but adding tests from PR [#603](https://github.com/google/adk-java/issues/603)) ([cdc5199](https://github.com/google/adk-java/commit/cdc5199eb0f92cb95db2ee7ff139d67317968457))
+* Ensure callbackContextData is preserved across session update ([d1e05ca](https://github.com/google/adk-java/commit/d1e05caf524b7cafb3f321550659296ea70d9286))
+* **firestore:** Remove hardcoded dependency version ([6a5a55e](https://github.com/google/adk-java/commit/6a5a55eb3e531c6f8a7083712308c4800f680ca5))
+* Fixing tracing for function calls ([84dff10](https://github.com/google/adk-java/commit/84dff10a3ee7f47e30a40409e56b5e9365c69815))
+* handle null `AiMessage.text()` to prevent NPE and add unit test (PR [#1035](https://github.com/google/adk-java/issues/1035)) ([3e21e7a](https://github.com/google/adk-java/commit/3e21e7ac46b634341819b3543388a38caef85516))
+* parallel agent execution ([677b6d7](https://github.com/google/adk-java/commit/677b6d7452aa28fab42d554d18c150d59ca88eec))
+* Removing deprecated methods from Runner ([3633a7d](https://github.com/google/adk-java/commit/3633a7dd071265087ea2ff148d419969b0c888ef))
+* resolve MCP tool parsing errors in Claude integration ([5a2abbf](https://github.com/google/adk-java/commit/5a2abbfe6f9e4e1ebdd5b918e34fcdb144603b5a))
+* revert changes to AbstractMcpTool, maintaining backwards compatible text_output field in the response ([5f34d59](https://github.com/google/adk-java/commit/5f34d598435a2a8d875a5dbb14344c201db0e75f))
+* Using App conformant agent names ([f3eb936](https://github.com/google/adk-java/commit/f3eb936772740b7dc7a803a40d0d39fdbccc4af4))
+
+
+### Documentation
+
+* add pull request template ([6bb721b](https://github.com/google/adk-java/commit/6bb721b9a6000dac9dfda498fb6dd2c45862e25c))
+
+
+### Miscellaneous Chores
+
+* set version to 1.0.0-rc.2 ([678b496](https://github.com/google/adk-java/commit/678b49653fa93606e2e57926213f0facaf9d6666))
+
