Unreleased

0.9.7 - 2026-07-05

Fixed

  • Treat tokenizer/parser exceptions from atom-free identifier encoding as parse failures so template-like invalid source files do not crash Hex indexing workers.

0.9.6 - 2026-07-05

Changed

  • Updated ExAST to 0.12.7 for tagged identifier support in structural matching, candidate terms, and symbol extraction.
  • Reworked Elixir parsing for indexed source to persist atom-free tagged identifiers instead of interning arbitrary package identifiers.
  • Reworked storage to persist atom-free whole-file ASTs once on files, hydrate fragments by node locators, drop persisted fragment AST blobs and fragment term arrays, and remove the unused tree_nodes table.
  • Reduced Hex-scale memory blowups by carrying file ASTs once per source file and using a higher default structural fragment threshold for generated files.

Fixed

  • Hydrate persisted AST binaries with safe binary term decoding.
  • Removed poisoned structural-name compatibility paths and stats now that identifier placeholders are no longer emitted.

0.9.5 - 2026-07-02

Fixed

  • Fixed a critical Hex-corpus parser/index poisoning bug where unknown package identifiers were silently replaced with :__exograph_unknown_atom__, causing structural search over the deployed Hex-wide index to return no matches for common patterns such as Repo.get!(_, _).
  • Added parser and indexing regression coverage asserting structural identifiers round-trip and Repo.get!(_, _) matches indexed package source.
  • Added a /api/stats poisoned_structural_names counter so poisoned module/function names are visible in deployed indexes.
  • Hardened API cursor decoding so malformed cursors fall back to the first page instead of raising.
  • Production Hex reindex release tasks now refuse to publish staged indexes when package indexing errors remain, defaulting EXOGRAPH_MAX_INDEX_ERRORS to 0.
  • Broadway indexing failures now preserve failure reasons and retry transient timeout/transport failures raised outside normal package result handling.
  • QuackDB shard repository transport receive/connect timeouts now default to 120s and can be configured with EXOGRAPH_QUACKDB_RECEIVE_TIMEOUT / EXOGRAPH_QUACKDB_CONNECT_TIMEOUT.

0.9.4 - 2026-06-29

Changed

  • Updated ExAST to 0.12.4 so Reach source-smell audits can use explicit nil, small integer, and call-argument literal terms for narrower exact candidate filtering.

0.9.3 - 2026-06-29

Fixed

  • Rebuild sharded fragment_terms lookup tables after shard workers finish so staged Hex indexes publish with structural candidate lookups populated.

Changed

  • Updated ExAST to 0.12.3.
  • Reach source smell audits now use optional ExAST index terms during exact candidate filtering, allowing newly indexed literal terms to reduce verification work without changing findings.

0.9.2 - 2026-06-28

Fixed

  • Materialize deferred fragment_terms rows during Hex corpus finalization so structural and Reach audit candidate lookups work on freshly indexed shards.

0.9.1 - 2026-06-28

Changed

  • Hex corpus indexing now parses package source with existing-only static atoms by default to avoid unbounded atom table growth from arbitrary source literals.

0.9.0 - 2026-06-28

Added

  • Added /api/health with release, runtime, and index metadata for deployment readiness checks.
  • Added web query and per-shard query telemetry with slow-query warnings.
  • Added Reach source-smell audit tooling, including reporting summaries, comparison mode, configurable candidate selection, and examples.
  • Added search execution metadata and lower-bound total reporting for broad DSL queries.

Changed

  • Removed the storage-engine selection layer; Exograph is DuckDB/QuackDB-only.
  • Removed legacy database-specific Mix options, tests, docs, and implementation modules.
  • Removed direct fragment(...) calls from Exograph source/test code in favor of Ecto DSL and QuackDB Ecto helpers.
  • Updated ReleaseKit integration through release_kit 0.3.1 and the assets: [volt: ...] artifact pipeline.
  • Updated ExAST to 0.12.1.
  • POST /api/search now accepts structural predicate shorthand such as contains(f, def handle_event(_, _, _)).
  • Improved web search result rendering with package-version hydration, named structural query totals, URL-persisted pagination, cleaner notices, and mobile layout refinements.
  • Improved simple text search by using BM25 where available and pushing down text contains filters.
  • Improved Reach audit performance with tuned defaults, parallel verification, lightweight candidate hydration, and skipped redundant exact candidate groups.
  • Optimized structural term lookup by clustering the fragment_terms table and always optimizing structural indexes after corpus indexing.
  • Reworked release reindexing to stage fresh shard builds before publishing manifests and reports.
  • Renamed and centralized storage schema/table configuration, declared storage tables and indexes in schema modules, and split storage config from hydration.
  • Mirrored Exograph test paths under test/exograph/ and documented the layout in AGENTS.md.
  • Removed Exograph-owned raw DuckDB SQL assembly from text search, fragment append, migration backfill, and offline staging paths.
  • Removed stale DuckDB compatibility paths and updated DuckDB ingestion/deployment documentation.

Fixed

  • Fixed DSL queries such as from(f in Fragment, where: matches(f, "def handle_call(_, _, _) do ... end"), limit: 20) so they are not treated as raw structural patterns.
  • Fixed fragment matches/2 semantics after structural result display changes.
  • Fixed PhoenixIconify release packaging/runtime behavior by configuring the OTP app and tracking the JSON manifest.
  • Started :inets and the default :httpc profile during application boot so release tasks can fetch Hex registry data reliably.
  • Included web asset sources in Hex packages so mix exograph.web can rebuild the UI from clean installs.

0.8.1 - 2026-06-18

Added

  • Added sharded DuckDB semantics documentation and included it in published docs.
  • Added safe DuckDB shard lifecycle helpers and manifest-open coverage.
  • Added package-scoped sharded routing support for map, keyword, and Exograph.PackageVersion filters.
  • Added sharded DuckDB web/CLI manifest usage documentation, including configurable shard port base for mix exograph.web.

Fixed

  • Fixed sharded DuckDB package-scoped text search filtering for DuckDB text-search paths.
  • Fixed sharded web UI package counts by summing packages across shard indexes.
  • Prevented manifest-owned but skipped packages from dropping package-version filters during sharded search.

0.8.0

Added

  • DuckDB/QuackDB storage for local indexing, search, web tasks, and Hex corpus indexing.
  • Managed DuckDB options for Mix tasks: --quackdb-uri, --quackdb-token, --duckdb-database, --duckdb-threads, and Hex corpus sharding with --duckdb-shards.
  • Dynamic sharded DuckDB corpus indexes with manifest persistence and fan-out query support.
  • Direct DuckDB fragment append path using QuackDB APIs while preserving full persisted data.

Changed

  • Switched to the published quackdb dependency.
  • Moved shared storage internals to Exograph.Storage.* and renamed storage table helpers to Exograph.Storage.Schema.
  • Updated docs around DuckDB/QuackDB corpus indexing and deployment.

Fixed

  • Stabilized sharded DuckDB benchmark/server teardown by using unique shard port bases and stopping dynamic shard repos.
  • Prevented local benchmark runs from leaving generated prefixes behind by default.

Older releases

Earlier releases introduced the web UI, JSON API, package indexing pipeline, code facts, DSL queries, ExAST-backed structural verification, optional Reach call graph extraction, and ExDNA structural similarity.
