 # scip-clang ChangeLog
 
+## v0.2.0 (beta)
+
+- Adds initial support for **cross-repository code navigation**.
+  (https://github.com/sourcegraph/scip-clang/pull/338)
+- Landed several performance optimizations around
+  skipping occurrence construction (https://github.com/sourcegraph/scip-clang/pull/348)
+  and using string interning with a bump allocator.
+  (https://github.com/sourcegraph/scip-clang/pull/337,
+  https://github.com/sourcegraph/scip-clang/pull/345)
+  Depending on proportion of code in a project-external dependency
+  vs in-project code, these together **reduce indexing time by 5%-50%**.
+- scip-clang now forces indexing of as much code as possible
+  in the presence of compiler errors (e.g. due to use
+  of unknown AVX or ARM instrinsics). This should improve
+  the code navigation experience for large files relying on
+  templated hash map/set types that use intrinsics.
+  (https://github.com/sourcegraph/scip-clang/pull/356)
+- Fixed code navigation for function-local `extern` declarations.
+  (https://github.com/sourcegraph/scip-clang/pull/362)
+- Added more graceful recovery when semantic analysis is
+  not run for some reason, such as when the command-line in
+  a compilation database entry is not fully correct.
+  For example, the compilation database
+  generated by grailbio/bazel-compilation-database
+  for Bazel projects may sometimes contain unexpanded Make variables.
+  (https://github.com/sourcegraph/scip-clang/pull/368)
+
 ## v0.1.3 (beta)
 
 - Fixes a crash when indexing dependent names in templates.
