All notable changes to this project are documented in this file.

[Unreleased]

Changed

  • Default local project version moved to 0.1.10-SNAPSHOT.

[0.1.10] - 2026-07-21

Added

  • Added MongoDB-style $min/$max update operators with BSON ordering, mixed numeric types, dates, dotted paths, upserts, and modifier conflict detection.

  • Expanded $group with core, set/object merge, percentile/median, and first/last/min/max/top/bottom N accumulators.
  • Added $setWindowFields partition/sort support with $shift, $documentNumber, $rank, and $denseRank.

[0.1.9] - 2026-05-09

Added

  • Added $unwind.includeArrayIndex support, including MongoDB-compatible null index handling for scalar and preserved null/missing/empty inputs.
  • Added listCollections, drop, and dropDatabase command handlers for metadata lookup and fixture cleanup flows.
  • Added UTF runCommand importer support for listCollections, distinct, drop, and dropDatabase.
  • Added tier-0 TTL runtime pruning for single-field expireAfterSeconds indexes using deterministic lazy cleanup.
  • Added regression coverage for findOneAndUpdate/upsert duplicate-key behavior when _id matches an existing document but other predicates do not, including $and-wrapped filters.
  • Added declarative fixture manifest schema (fixture-manifest.v1) with standardized dev/smoke/full profile model.
  • Added fixture manifest loader/validator with path-aware aggregated validation errors.
  • Added deterministic fixture extraction planner + profile fingerprint generation.
  • Added fixture manifest CLI utility (FixtureManifestTool) and Gradle task (fixtureManifestPlan) for profile plan validation/output.
  • Added sample fixture manifest templates under testkit/fixture/manifests.
  • Added fixture manifest onboarding documentation (docs/FIXTURE_MANIFEST.md).
  • Added fixture usage/operations playbook (docs/FIXTURE_PLAYBOOK.md) for developer/reviewer/operator workflows.
  • Added Node adapter replica-set profile contract tests for URI/env propagation and hello handshake invariants.
  • Added Node adapter topology-profile/URI option sync validation with mismatch regression tests.
  • Added Jest global setup/teardown stabilization for idempotent state reuse and stale state auto-recovery.
  • Added Vitest workspace helper for project-level DB/env isolation policy.
  • Added Nest Jest adapter hardened defaults (MONGODB_URI+DATABASE_URL, worker DB isolation) with override coverage.
  • Added Express integration smoke scenario and recipe coverage in node-compat suite.
  • Added Koa integration smoke scenario and recipe coverage in node-compat suite.
  • Added Mongoose transaction/session smoke harness scenario with session visibility/commit coverage.
  • Added TypeORM MongoDB repository CRUD smoke harness scenario in node-compat suite.
  • Added Prisma MongoDB provider CRUD smoke harness with generated client workflow in node-compat suite.
  • Added node adapter compatibility CI matrix across Ubuntu/macOS and Node 20/22.
  • Added npm release pipeline tarball attestation flow (actions/attest-build-provenance) for binary/core Node packages.
  • Added Node adapter canary pre-release workflow with canary dist-tag publish automation and attested tarball flow.
  • Added Node adapter semver/compatibility policy documentation (docs/NODE_SEMVER_POLICY.md).
  • Added dedicated migration guide from mongodb-memory-server to @jongodb/memory-server.
  • Added Node adapter troubleshooting playbook mapped by error signatures.
  • Added strict Node API type coverage report workflow and export coverage report artifact.
  • Added ESM/CJS dual-export contract smoke checks for Node adapter entrypoints.
  • Added Node cold-start benchmark suite with CI budget gate and report artifacts.
  • Added runtime launcher log secret redaction policy and regression coverage.
  • Added Node debug bundle collector CLI and issue template for reproducible support reports.
  • Added startup latency telemetry hook for launch attempts (including auto fallback success/failure events).
  • Added node:doctor launcher preflight diagnostics command with structured report output.
  • Added Java classpath auto-discovery fallback hardening for auto/java launch modes with configurable probe command/cwd.
  • Added runtime SHA-256 binary integrity verification for bundled binaries and explicit binaryChecksum/JONGODB_BINARY_CHECKSUM paths.
  • Added local classpath-discovery artifact cache with TTL/quota pruning policy and configurable cache limits.
  • Added process-exit launcher cleanup hook (cleanupOnProcessExit) to reduce orphan runtime processes after abrupt test termination.
  • Added fixed-port collision retry/backoff strategy (portRetryAttempts, portRetryBackoffMs) with next-port fallback behavior.
  • Added structured runtime logging contract (onLog, logFormat) with expanded log levels (error/warn/info/debug).

Fixed

  • Fixed insert parity for documents missing _id by assigning an ObjectId before unique-index validation.
  • Fixed release-gate runOn lanes to keep mongos-unpin and client-bulkWrite-errors* suites gated until their exact differential contracts are implemented.
  • Fixed deterministic R3 parity mismatches for dollar-prefixed _id subfields, replacement-style updateMany, and createIndexes inside transactions.
  • Fixed upsert seed extraction to honor equality clauses nested inside $and, restoring duplicate-key behavior for findOneAndUpdate lock-style filters.

Changed

  • Default local project version moved to 0.1.9-SNAPSHOT before the v0.1.9 release.

[0.1.3] - 2026-02-24

Added

  • Added real-mongod differential execution adapter path for UTF bulkWrite scenarios.
  • Added transaction regression coverage for:
    • repeated commitTransaction replay behavior
    • abortTransaction after commitTransaction
    • commit-time write conflict handling across concurrent transactions
  • Added explicit engine exception type for commit-time write conflict detection.

Fixed

  • Resolved remaining official UTF differential mismatches for imported crud, transactions, and sessions suites.
  • Fixed bulkWrite update validation to require atomic-modifier style updates.
  • Fixed replaceOne validation parity in real-mongod differential backend.
  • Fixed null _id upsert result propagation so update/replace upsert counters align with reference behavior.

Changed

  • Added default _id unique index behavior to the in-memory collection store.
  • Strengthened transaction terminal-state handling (COMMITTED/ABORTED) for retry and post-terminal command semantics.
  • Updated compatibility scorecard snapshot to current failureCount=0 R3 ledger evidence.
  • Default local project version moved to 0.1.3-SNAPSHOT.

[0.1.2] - 2026-02-24

Added

  • Added single-hook Spring test bootstrap annotation: @JongodbMongoTest.
  • Added command handlers for countDocuments, replaceOne, findOneAndUpdate, findOneAndReplace.
  • Added ordered bulkWrite core subset support.
  • Expanded findOneAndUpdate / findOneAndReplace projection subset behavior.
  • Added PR CI workflow .github/workflows/ci-test-suite.yml to enforce clean test on PRs and main.

Fixed

  • Included aggregate in transactional command routing so transaction-scoped aggregate operations use the transaction snapshot.
  • Added regression coverage for transactional aggregate visibility and post-commit publish behavior.

Changed

  • Maven release workflow now runs clean test before staging/deploy.
  • Default local project version moved to 0.1.2-SNAPSHOT.
  • Updated README and release docs to distinguish v0.1.1 certification baseline from current main.

[0.1.1] - 2026-02-24

Fixed

  • Replaced full-store transaction snapshot publish with namespace-aware merge on commit.
  • Preserved out-of-transaction writes interleaved during an open transaction, including same-namespace writes with different _id values.

Behavior

  • Added deterministic same-document conflict policy: when transactional and non-transactional writes target the same _id, commit applies the transactional version.

Testing

  • Added mixed transactional/non-transactional regression scenarios for commit and abort paths.
  • Expanded Spring compatibility matrix scenarios for multi-template transaction paths and interleaving write cases.
  • Verified full test suite and Spring matrix evidence generation on release branch.

[0.1.0] - 2026-02-24

Initial public release.

Added

  • In-memory MongoDB-compatible command engine for Spring integration tests.
  • In-process command ingress with deterministic unsupported-feature responses.
  • Differential/evidence tooling for compatibility and release readiness.

  • Maven path: https://repo1.maven.org/maven2/io/github/midagedev/jongodb/0.1.0/
