[Unreleased]

[0.2.0] - 2026-10-21

Added

• Added regression coverage for dependency graph dependent-index updates
• Added ReScript 12 support for value usage analysis (-vb) by decoding typed trees with the layout of the compiler that wrote each .cmt file
• Added ReScript 12 fixture projects (standard and namespaced) with dependency graph and value usage regression tests
• Added ReScript 13 support: dependency analysis for the 13.0 alphas, and value usage analysis (-vb) for 13.0.0-alpha.1 to alpha.3, alpha.5 and alpha.6. -vb reports -6 for compilers it cannot decode, such as 13.0.0-alpha.4
• Added ReScript 13 fixture projects and self-contained compiler identification tests
• Added a supported ReScript versions table to the README

Changed

• Organized typed tree decoding into one backend per compiler release (Compiler_v11, Compiler_v12, Compiler_v13) selected by the CMT magic number, the cmt_infos layout and the compiler version in lib/bs/compiler-info.json, with decoders skipping constructors added by later releases instead of misreading them
• .cmt files written by unknown compilers now stop the analysis with an error instead of silently producing an empty graph
• Improved dependency graph performance by maintaining a reverse dependent index instead of scanning the full graph for each dependent lookup
• Reduced VS Code inline value usage analysis work with debounced requests, short-lived result caching, and JSON output parsing

Fixed

• Prevented stale VS Code inline value usage decorations from appearing after source edits or outdated CLI responses
• Improved inline value usage cache invalidation when ReScript build artifacts change
• Fixed a segmentation fault when counting value usage (-vb) in projects built with ReScript 12
• Fixed namespaced projects so imports are filtered by each module's .ast file again; ReScript 12 runtime modules (Stdlib_*, Primitive_*) and unused imports no longer appear as dependencies, and the generated namespace module is no longer shown as a node
• Fixed value usage analysis (-vb) in namespaced projects
• Read the ReScript 12 dependencies and dev-dependencies fields of rescript.json when resolving external module paths
• Read .ast headers by their byte length so data from the binary AST is never taken as module references
• Aligned the vendored ReScript 11 typedtree with the compiler's constructor layout

[0.1.2] - 2026-04-22

Fixed

• Fixed the generated opam metadata tags so opam lint no longer reports the default example topics tag
• Fixed the opam test suite by keeping @runtest self-contained instead of depending on locally built ReScript fixture outputs
• Improved fixture path resolution for local integration tests executed from build directories

[0.1.1] - 2026-04-18

Fixed

• Fixed an issue where standard modules were not filtered when the -m flag was not used
• Fixed focused module dependency analysis for projects using namespace in rescript.json
• Improved CI resilience against transient opam dependency fetch failures

Added

• Static linking support for Linux environments
• Performance benchmarking mode with --benchmark flag
• Added a Makefile-based test workflow for local and CI runs
• Added namespace-focused regression coverage

Changed

• Removed file-based cache persistence in favor of in-memory caching only
• Removed --cache-file option completely
• Enhanced error handling for workspace analysis
• Improved progress reporting in VS Code extension
• Removed outdated Rewatch-specific test fixtures and compatibility logic, keeping analysis focused on compiler-generated .cmt and .ast files
