v0.8.0

The headline: three new type-aware LSP engines. Java, Kotlin, and Rust now get full hybrid LSP resolution — type-aware call resolution through class hierarchies, annotation/attribute linkage, signature-aware overload matching, generics handling, and cross-file type inference — joining C/C++, Python, TypeScript/JavaScript, Go, C#, and PHP for 9 languages under hybrid LSP.

Architecture intelligence

• Leiden community detection: get_architecture now surfaces multi-level Leiden communities (replacing single-level Louvain) — real module boundaries on kernel-sized graphs, computed in seconds instead of minutes.
• Queryable computation-bottleneck metrics: functions carry complexity, loop-depth, and scan-pattern metrics in the graph — you can now Cypher-query your codebase for its own algorithmic hotspots. (We used exactly this to find and fix several of our own, see below.)
• Helm support: chart templates, include call linkage, and Chart.yaml dependency edges; HCL block labels folded into node names; C/C++ preprocessor macros are now first-class Macro nodes (2.3M of them in the Linux kernel).

Stability — the biggest hardening push so far

The release fleet now indexes 16 large OSS repos end-to-end — the Linux kernel (4.8M nodes), elasticsearch, kubernetes, the TypeScript compiler, bitcoin, zig, symfony, and more — with database-level validity gates. That hunt, plus outstanding community reports, closed a long list of crashes:

• C++/templated-code crash family eliminated: uninitialized template-argument arrays, out-of-bounds parameter lookups, unbounded resolve recursion, expression-evaluation blowups — reported across #424, #427/#428/#432, #312, #322/#323, #336, #344, #355, #360, #385.
• Allocator unification (#424): the whole binary — vendored tree-sitter, SQLite, libgit2 — now runs under one allocator, ending a class of cross-allocator heap corruption on complex C++.
• Startup crash-loop fixed (#235, #439): a stack-buffer overflow in the project-list error path could SIGABRT the server for all projects; one corrupt cache DB no longer takes down every session.
• Database integrity, end to end: oversized index keys now spill to overflow pages correctly, all properties JSON is escaped and validated at the producer, the url_path index always matches its generated column, and WAL files are checkpointed on close/startup (#387). Every database in the 16-repo fleet passes PRAGMA integrity_check clean.
• Server lifecycle: stdio servers exit with their parent via a death watchdog (#406), MCP ping is supported (#354), JSON-RPC string ids are preserved (#253), log level is configurable via CBM_LOG_LEVEL (#413).
• Windows: wide-char API for non-ASCII paths (#386), cmd.exe-compatible git history pass (#324), PATHEXT probing (#221), packaging-walk hang fixed — the full test suite is green on Windows.
• Plus: phantom gRPC routes (#294), moderate-mode silently dropping subtrees (#411) with excluded directories now reported in indexing results, validator-safe project names (#349), UI flag diagnostics (#350).

Performance at kernel scale

• Memory rework: streaming SQLite dump writer, string interning, allocator page reclaim, and extraction back-pressure — the full Linux kernel indexes in ~4 minutes on a laptop, within a bounded memory budget; cgroup-aware CPU/memory detection and a CBM_WORKERS override (#364/#365) make container behavior predictable.
• Quadratic hot paths eliminated, several found by pointing the new bottleneck metrics at our own codebase: C/C++ cross-LSP overload resolution (#410), registry construction and lookup paths in the PHP/Python/Java/Kotlin resolvers, and architecture-boundary computation. Large PHP and Java monorepos see order-of-magnitude faster full indexes (symfony 35x, elasticsearch 9x vs. this cycle's early builds).
• Graph quality improved throughout these fixes — resolution coverage and edge fidelity are better in every supported language.

Query layer

• Cypher: EXISTS {} predicates in WHERE, COUNT(DISTINCT) (#239), label alternation (n:A|B) (#242), label tests in WHERE (#241), WITH DISTINCT (#238), string/scalar/entity-introspection functions, multi-argument scalars — and unsupported syntax now fails loudly instead of returning silent empties (#373).
• search_code: invalid regex errors instead of empty results (#283), & in paths, timing in responses, wildcard-free file_pattern as substring (#200), .mjs/.cjs/.mts/.cts indexed (#197), Blade templates mapped (#258), R box::use()/library() imports (#218/#219).

A much bigger safety net

• New per-grammar regression suite across all 159 grammars plus probe suites for extraction, edge creation, and LSP resolution — the suite now runs 5,500+ tests under a strict no-skip policy (skips are hard failures).
• Crash reproductions execute as subprocess-isolated tests with exit-signal assertions; ASan/LSan run across the suite; the macOS Intel build leg is now blocking so darwin-amd64 always ships.

Distribution & integrations

• Published to the official MCP Registry and the Glama directory; portable static Linux binary on all install/update paths.
• install --plan machine-readable receipts before any config mutation (#388), Cursor IDE detection (#222), fish-native PATH handling (#319), $CLAUDE_CONFIG_DIR respected (#321), SessionStart hooks for Codex, Gemini CLI, and Antigravity (#330), ADR storage unified between MCP tools and the UI (#256).
