Changelog

Notable changes to this list, grouped by month (newest first). The format is adapted from Keep a Changelog; as a curated list, this repository does not use semantic versions. Planned work is tracked in ROADMAP.md.

2026-07

Added

  • PR validation suite: every pull request now runs ~15 automated checks (OpenClaw-inspired). A new pr-validation workflow fans out scripts/pr_entry_validator.py across six blocking entry checks (format, alphabetical order, duplicates, verified markers, style bans, evidence tags), validates the PR body against the template policy, link-checks the changed files (advisory), and runs pytest/ruff when Python tooling changes. A pr-labeler workflow adds area/* and size/* labels.
  • Shared entry-grammar module (scripts/entry_patterns.py) reused by the discovery engine and the PR validator, plus unit tests for every check.
  • Shared lychee.toml so the weekly link checker and the per-PR link check use one configuration; pyproject.toml with ruff and pytest settings.
  • CONTRIBUTING: new "CI Checks on Pull Requests" section documenting each check, its gate, and the <!-- no-alphabetical --> / <!-- allow-duplicate --> escape hatches (now marking intentionally curated sections and cross-listings).

Fixed

  • Evidence hygiene: reworded two unsourced numeric claims (ARES, PrivateGPT) and tagged the managed-SLA figure in vector-database-comparison.md as vendor-stated, per the Evidence Tier policy.

2026-06

Added

  • New tools: Omnigraph (Vector Databases), psql_bm25s (Retrieval & Reranking), KB Arena (Evaluation & Benchmarking), and Future AGI (Observability & Tracing).
  • PaddleOCR added to Data Ingestion & Parsing (Apache-2.0 OCR / document-parsing toolkit).
  • RAG Made Simple added to the RAG section of the recommended books list (books.md).
  • FAQ (FAQ.md) answering the most common scope, evidence, and contribution questions.
  • This changelog (CHANGELOG.md) and a public roadmap (ROADMAP.md).
  • Internal repository audit (REPO-ANALIZ.md) with a re-scored 2026-06-12 review.
  • Per-entry "last verified" convention (CONTRIBUTING § 5): an optional verified: YYYY-MM-DD marker for the last human review, audited weekly by discovery_engine.py, with the engine's first unit tests.
  • Live documentation site (MkDocs Material) at https://yigtwxx.github.io/awesome-rag-production/, auto-deployed from main via the docs workflow, with build-time markdown staging (docs-site/stage_docs.sh), a per-page SEO meta-description hook, and a GitHub social preview card.
  • Discovery engine (scripts/discovery_engine.py): a weekly freshness audit that flags listed tools with no push in 180+ days, benchmark citations older than 365 days, and stale per-entry verified dates, wired into the discovery workflow.
  • New decision guide: vector-database-comparison.md, covering scale, filtering, hybrid search, and cost trade-offs.
  • README: production inclusion criteria and quick-start decision guides.

Removed

  • A short-lived stale-link-audit workflow (added 2026-06-01, removed 2026-06-09); weekly link checking remains covered by the link-check workflow.

2026-05

Added

  • benchmarks.md with the [3P] / [V] / [A] evidence-tag system, a Methodology Disputes section, and an explicit Gaps section.
  • Evidence Tier policy in CONTRIBUTING.md — numeric claims now require a source URL, date, tag, and methodology link.
  • Removal & Deprecation Policy in CONTRIBUTING.md.
  • README sections: Embedding Fine-tuning, Data & Index Versioning, FinOps & Cost Management, Agent Memory & Stateful Context, Structured & SQL RAG, and Tutorials & Hands-on Code.
  • Discovery engine freshness audit: flags listed tools with no push in 180+ days and benchmark citations older than 365 days.
  • Multimodal RAG and Caching & Performance sections.
  • Domain benchmark suites (legal, medical, financial) in datasets.md.
  • New tools: DSPy, Crawl4AI, Docling, Vespa, TruLens, Opik.
  • CI status badges (Markdown Lint, Link Check, Weekly Discovery) plus welcome and stale automation workflows.
  • Dependabot configuration for GitHub Actions and pip dependencies.

Fixed

  • Two weekly workflow failures; bumped actions/setup-python from 5.3.0 to 6.2.0.

2026-04

Added

  • Weekly automated discovery workflow (trending RAG repositories via the GitHub API).
  • Must-watch production talks in showcase.md.
  • Dedicated RAG section in the recommended books list.

Changed

  • Repository-wide style standardization: removed decorative emojis, simplified markdown styling, and added the pull request template.

Changed

Fixed

  • Removed or replaced a large batch of broken resource links.

2025-12

  • Markdown lint workflow and issue / discussion templates.
