+## BitLogger Update Changes
+
+version 0.5.1
+
+### Docs
+
+- docs: simplify the Chinese and English README entry pages so they focus on what BitLogger is, how to start, and where to find examples and API docs
+- docs: remove misplaced banner-style content and reduce overly dense engineering wording in release-facing README sections
+- docs: clarify API-side target verification wording and add a small verification note for current release claims
+
+### Example
+
+- docs: align portable examples with the recommended `build_logger(...)` entry path and keep native-only example boundaries explicit
+
+### Test
+
+- test: strengthen cross-target capability checks for configured file logging, fallback file behavior, and async runtime mode reporting
+
+### Notes
+
+- this is a small follow-up release focused on release-facing clarity rather than new core functionality
+- verified release-facing targets remain `native`, `js`, `wasm`, and `wasm-gc`, while `llvm` is still treated as experimental in the current environment
