+### Added
+- ClickHouse SQL dialect support (`DialectClickHouse = "clickhouse"`) with 30+ keywords
+- `PrewhereClause` field on `SelectStatement` AST for ClickHouse PREWHERE optimization
+- `Final` field on `TableReference` for ClickHouse MergeTree FINAL modifier
+- PREWHERE clause parsing in ClickHouse dialect mode
+- FINAL modifier parsing in ClickHouse dialect mode
+- GLOBAL IN / GLOBAL NOT IN expression parsing (ClickHouse)
+- ClickHouse data types: FixedString, LowCardinality, Nullable, DateTime64, IPv4, IPv6
+- MergeTree engine family keywords (MERGETREE, REPLACINGMERGETREE, AGGREGATINGMERGETREE, etc.)
+- LSP semantic token provider (`textDocument/semanticTokens/full`) with 6-type legend: keyword, identifier, number, string, operator, comment
+- LSP diagnostic debouncing (300ms) — prevents excessive re-parsing on rapid typing
+- LSP document cleanup on `textDocument/didClose`
+- Glama MCP registry integration with stdio transport support
+- Auto-trigger Glama build on GitHub release via CI (`glama-sync.yml`)
+- Sentry error monitoring, tracing, and session replay on website
+
+### Changed
+- `ParseFromModelTokens` is now the canonical parse entry point (positions always populated)
+- Docker base image Go 1.25 → 1.26 to match go.mod requirement
+- Next.js 16.1.6 → 16.1.7 (CVE-2026-27979, CVE-2026-27980, CVE-2026-29057)
+- Website rebuilt on Next.js 16 App Router with comprehensive a11y, SEO, and performance audit
+- Lighthouse Desktop: 100 Performance / 100 Accessibility / 100 SEO (maintained)
+- CI: Vercel deployment working-directory bug fixed (doubled path `website/website/`)
+
+### Deprecated
+- `parser.Parse([]token.Token)` — use `ParseFromModelTokens` instead
+- `ParseFromModelTokensWithPositions` — consolidated into `ParseFromModelTokens`
+- `ConversionResult.PositionMapping` — always nil, will be removed in v2
+
+### Fixed
+- Production playground WASM 404 (CI working-directory path doubling)
+- WASM service worker cache versioning
+- Broken `.md` relative links in docs → `/docs/` URL paths
+- JSON-LD BreadcrumbList and Article markup on docs pages
+- Horizontal overflow at 320–390px viewport
+- Keyboard accessibility (tabIndex) on scrollable code blocks
