📜 Changelog

❌️ Breaking changes

• Removed completeness checking logic in CacheLookupScheduler (#826). To migrate, remove the "cas_store" field in CacheLookupScheduler configurations and use the CompletenessCheckingStore wrapper.
• Generalized LRE to arbitrary toolchains and refactored image publishing worflows (#728). NativeLink containers no longer ship with cacerts. Instead, an external CA needs to be mounted into the image explicitly. See deployment-examples/kubernetes for updated deployment instructions.
• The /status endpoint now returns a JSON status object (#636).
• The GRPCScheduler and GRPCStore no longer take a string as endpoint but a new GRPCEndpointConfig object which bundles the endpoint string and TLS configuration and has an optional field for concurrency limits (#627).
• Unknown fields during configuration initialization will now raise errors (#693). This breaks configurations which were already faulty but would previously be accepted silently.

✨ Major changes

• NativeLink now supports mTLS (#470)
• The VerifyStore now supports blake3 (#575)
• Documentation is now generated via Docusaurus (#586)

• Bazel builds now use Bzlmod (#626)
• CompressionStore and ExistenceCacheStore now support metrics (#647)
• NativeLink Production deployments are now built against musl libc (#583) and use mimalloc (#749) as memory allocator.
• Action directories during remote execution now run under a configurable root directory (#752)
• Added a chromium/Reclient example (#786)
• A new nativelink-worker-lre-cc image for C++ remote execution is now published from main (#794)
• A new nativelink-debug target has been added to the nix flake to aid debugging concurrency issues (#811)
