   - Comprehensive unit tests in `scripts/__tests__/wceu-validation-scripts.test.js` validating script structure, syntax, and completeness
   - Updated `scripts/README.md` with usage examples and feature documentation ([#13](https://github.com/lightspeedwp/.github/issues/13), [#16](https://github.com/lightspeedwp/.github/issues/16))
 
+- **Release Automation Framework Phase 2: Semantic Versioning & Release Notes Generation** — Implemented core semantic versioning detection and release notes formatting modules enabling automated version bumping and changelog generation ([#598](https://github.com/lightspeedwp/.github/pull/598)):
+  - `scripts/agents/includes/versionDetector.js` — Semantic version bump detection from changelog entries with Conventional Commits integration. Analyzes breaking changes, feature additions, deprecations, and removals to determine patch/minor/major version bumps per Semantic Versioning 2.0.0. Functions: parseVersion, formatVersion, compareVersions, determineBumpType, calculateNextVersion, detectBump, suggestNextVersion
+  - `scripts/agents/includes/releaseNotesFormatter.js` — Release notes generation from changelog entries with Markdown formatting and metadata support (scope, commit hash, PR number, author). Configurable section ordering (security → removed → deprecated → added → changed → fixed → documentation → performance) and summary text generation. Functions: formatSectionTitle, formatEntry, buildReleaseNotes, generateReleaseNotes, extractSummary, generateSummaryText
+  - `scripts/agents/includes/duplicateDetector.js` — Enhanced duplicate detection using fuzzy matching with Levenshtein distance algorithm and semantic analysis via key-term overlap. Configurable similarity threshold (default 0.85). Functions: normalize, levenshteinDistance, calculateSimilarity, isFuzzyDuplicate, hasSemanticDuplicate, findBestMatch, deduplicateEntries, groupDuplicates
+  - Comprehensive test coverage: 99 Jest tests across all three modules (32 versionDetector tests, 27 releaseNotesFormatter tests, 40 duplicateDetector tests) with >90% code coverage
+  - Integration tests validate semantic versioning logic, Markdown formatting, fuzzy matching algorithms, and edge case handling
+
 - **Complete Agent Specifications & Documentation Audit** — Completed specification documentation for tracking agents and audited documentation cross-references:
   - Completed `agents/template.agent.md` with canonical agent specification template, usage guidelines, structure documentation, and best practices ([#488](https://github.com/lightspeedwp/.github/issues/488))
   - Enhanced `agents/testing.agent.md` with comprehensive role/responsibilities, capabilities, configuration, examples, and related agent references ([#490](https://github.com/lightspeedwp/.github/issues/490))
