12.2.0-rc.1

💥 Breaking Change

• js-post-build now passes the correct output file path based on in-source configuration: when in-source: true, the path next to the source file is passed; when in-source: false, the path in the lib/<module>/ directory is passed. Additionally, stdout and stderr from the post-build command are now logged. #8190
• js-post-build command now runs in the directory containing the rescript.json where it is defined, instead of the unpredictable build invocation directory. This provides consistent behavior in monorepos. #8195

🚀 New Feature

• Reanalyze: add scoped @@live/@@dead annotations for marking module/file sections as live or dead. #8197

🐛 Bug fix

• Reanalyze: fix reactive/server stale results when cross-file references change without changing dead declarations (non-transitive mode). #8173
• Reanalyze: link record/variant label liveness across type re-exports (type y = x = {...}). #8217
• Add duplicate package detection to rewatch. #8180
• Rewatch: do not warn about "reanalyze" config field. #8181
• Fix error when importing CommonJS runtime modules with require(). #8194
• Rewatch: fix warnings from non-recompiled modules being lost during incremental builds in watch mode. #8216

💅 Polish

• Formatter no longer writes files when contents are already correctly formatted. #8209
• Build system: Only log verbose "Generating AST for module" when actually parsing. #8210
• Build system: Watch only source folders from build state instead of the entire project directory, and report missing configured source folders. #8219
