Due to the period of time between this release and v0.0.26, many relevant changes and fixes may not appear in the following list. For a complete list of changes, please check the commit logs: https://github.com/google/kythe/compare/v0.0.26...v0.0.27

Notable additions:

• First release of Go indexer and Go extractors.
• Objective C is now supported in the C++ indexer.
• identifier.proto: adds a new IdentifierService API.
• Runtime plugins can be added to the Java indexer.

Notable changes:

• Remove gRPC server and client code.
• Schema:
  • Anchors no longer have childof edges to their parent file.
  • Anchor nodes must share their path, root, and corpus VName
    components with their parent file.
• Format strings have been replaced by the MarkedSource protobuf message.
• C++ analysis:
  • Included files are referenced by the ref/file edge.
  • code facts (containing MarkedSource protos) are emitted.
  • Better support for C++11, 14, and 17.
  • Limited CUDA support.
  • Improvements to indexing and rendering of documentation.
  • Added a plugin for indexing proto fields in certain string literals.
  • Type ranges for builtin structural types are no longer destructured (T*
    is now [T]*, not [[T]*]).
  • Decoration of builtin types can be controlled with
    --emit_anchors_on_builtins.
  • Namespaces are never defined, only refd.
  • Old-style name nodes removed.
  • The extractor now captures more build state, enabling support for
    __has_include
  • anchors involved in completes edges now contain their targets mixed
    with their signatures, making each completion relationship unique.
  • Support for indexing uses of make_unique et al as direct references to
    the relevant constructor.
  • Template instantiations can be aliased together with
    --experimental_alias_template_instantiations, which significantly
    decreases output size at the expense of lower fidelity.
• Java analysis:
  • name nodes are now defined as JVM binary names.
  • diagnostic nodes are emitted on errors.
  • code facts (MarkedSource protos) are emitted.
  • Add callgraph edges for constructors.
  • Non-member classes are now childof their enclosing method.
  • Local variables are now childof their enclosing method.
  • Blame calls in static initializers on the enclosing class.
  • Emit references for all matching members of a static import.
  • Reference abs nodes for generic classes instead of their record nodes.
  • Emit data for annotation arguments.
  • Emit package relations from package-info.java files.
• Protocol Buffers:
  • analysis.proto: add revision and build ID to AnalysisRequest.
  • analysis.proto: add AnalysisResult summary to AnalysisOutput.
  • analysis.proto: remove revision from CompilationUnit.
  • graph.proto: new location of the GraphService API
  • xref.proto: remove DecorationsReply.Reference.source_ticket.
  • xref.proto: add Diagnostic messages to DecorationsReply.
  • xref.proto: replace Location.Point pairs with common.Span.
  • xref.proto: by default, elide snippets from xrefs/decor replies.
  • xref.proto: replace Printable formats with MarkedSource.
  • xref.proto: allow filtering related nodes in the xrefs reply.
