v0.4.0

Import resolution (core)

• Import resolution (resolve_imports): resolves imports.resolved_file_id for TS/JS/Python
• Language-specific resolvers extracted to memos/query/import_resolver.py
• Python absolute intra-package imports resolved (e.g. memos.core.db → file)
• TS/JS absolute imports resolved via tsconfig.json/jsconfig.json — baseUrl and paths aliases with * wildcard support
• Go in-module imports resolved via go.mod module prefix
• find_dead_imports now distinguishes broken relative imports vs truly external packages
• Integration: resolve_imports called from memos index, MCP open_project, MCP reindex_file_tool, and memos watch

Git-aware incremental indexing

• memos index --since <ref> — only reindex files changed since a git ref
• memos index --dirty — reindex uncommitted changes only
• Deleted files cleaned up automatically from the index

Impact analysis & diagnostics

• Rename impact: word-boundary regex (\b) instead of SQL LIKE — no false positives (e.g. Config ≠ ConfigLoader)
• memos query diff-range --since <ref> — aggregated PR impact report per file
• MCP diff_range_impact_tool(since, project) — same report via MCP
• memos doctor — index freshness, schema, embeddings, unresolved edges diagnostics

Performance

• Batch embedding: single model, chunked by 256 with rich Progress bar
• --profile flag on memos index prints phase timings (parse/embed/resolve)
• scripts/benchmark_index.py — measures parse/embed/resolve/cold-warm query latency
• Migration 0005: composite index symbols(name, file_id) for faster resolve
• Fixed N+1 in resolve_call_edges (batch SELECT vs per-edge loop)
• Query-efficiency regression guard (N+1 guard test)

Language support

• JavaScript (.js/.jsx) support: require() → import, module.exports ignored

Tooling & DX

• MCP: _tracked decorator counts per-session tool usage via usage_stats_tool
• File watching: memos watch auto-reindexes on file changes (watchdog, 500ms debounce)

Packaging

• CI smoke-test: build wheel → install in isolated venv → end-to-end
• Migration presence test (guarantees ≥5 migrations)
• Python 3.12 + 3.13 CI matrix
• Release workflow: tag verification, automated PyPI publish, GitHub Release with changelog

v0.3.0

• JavaScript (.js/.jsx) support: require() → import (not call), module.exports ignored
• Packaging hardening: CI smoke-test, migration presence test, Python 3.12+3.13 matrix
• Performance: batch embedding (single model, chunked by 256, rich Progress bar)
• Benchmarks: --profile flag, scripts/benchmark_index.py, query-efficiency regression test
• Migration 0005: composite index symbols(name, file_id) for faster resolve
• Fixed N+1 in resolve_call_edges (batch SELECT vs per-edge loop)
• Adoption tooling: memos doctor, memos watch, usage_stats_tool
• Diagnostics: memos doctor checks index freshness, schema, embeddings, unresolved edges
• MCP: _tracked decorator counts per-session tool usage via usage_stats_tool
• File watching: memos watch auto-reindexes on file changes (watchdog, 500ms debounce)
