 ## Unreleased
 
+## [2.1.0](https://github.com/PatrickSys/codebase-context/compare/v1.9.0...v2.1.0) (2026-04-13)
+
 ### Features
 
+- **search:** surface chunk intelligence directly in `search_codebase` results, including symbol identity, scope, signature preview, and compact/full response budgeting
+- **map:** upgrade the conventions map with structural skeleton sections and add `map --export` so the compact map can be written to `CODEBASE_MAP.md`
 - **mcp:** rework multi-project routing so one MCP server can serve multiple projects instead of one hardcoded server entry per repo
 - **mcp:** keep explicit `project` as the fallback when the client does not provide enough project context
 - **mcp:** accept repo paths, subproject paths, and file paths as `project` selectors when routing is ambiguous
 
 ### Bug Fixes
 
+- **metadata:** require real dependency evidence plus multiple framework indicators before labeling a repo as Next.js or another specialized framework
+- **reranker:** auto-heal corrupted cross-encoder cache entries and surface degraded reranker state in `searchQuality.rerankerStatus`
+- **benchmarks:** harden comparator lanes for cross-platform execution and keep setup failures explicit instead of silently turning them into claims
 - **search:** auto-heal on corrupted index now triggers a background rebuild instead of blocking the search response
 
 ### Documentation
 
+- publish the v2.1.0 discovery benchmark rerun with the current gate output: `pending_evidence`, `claimAllowed: false`, `24` frozen tasks, `0.75` average usefulness, and `1822.25` average estimated tokens
+- document the current comparator truth instead of stale assumptions: the public proof still has setup failures plus near-empty comparator outputs on this host, so benchmark win claims remain blocked
+- note the new `searchQuality.tokenEstimate` advisory contract: estimates are based on the final serialized response payload and warnings only appear above the 4K-token threshold
 - simplify the setup story around a roots-first contract: roots-capable multi-project sessions, single-project fallback, and explicit `project` retries
 - clarify that issue #63 fixed the architecture and workspace-aware workflow, but issue #2 is still only partially solved when the client does not provide roots or active-project context
 - remove the repo-local `init` / marker-file story from the public setup guidance
