fix: strip email domain from user identifier for environment endpoint

If preferred_username is an email (user@domain.com), extract just the
username part to match Qdrant collection naming (volatile_user).

@@ -5,6 +5,77 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.10.9] - 2026-01-08
+
+### Fixed
+
+- **Environment user ID cleanup** - Strip email domain from user identifier
+  - If `preferred_username` is an email, extract just the username part
+  - Ensures Qdrant collection name matches (e.g., `volatile_jpmschweitzer` not `volatile_jpmschweitzer@gmail.com`)
+
+## [1.10.8] - 2026-01-08
+
+### Fixed
+
+- **OIDC audience validation** - python-jose requires string audience, not list
+  - Extract and validate audience from unverified claims first
+  - Use token's actual audience for JWT decode (after validating it's allowed)
+  - Fixes "audience must be a string or None" error
+
+## [1.10.7] - 2026-01-08
+
+### Added
+
+- **Multi-issuer OIDC support** - Accept tokens from multiple OAuth providers
+  - Changed `oidc_issuer` (string) to `oidc_issuers` (list)
+  - Each issuer has its own JWKS endpoint, now cached per-issuer
+  - Validates token issuer against allowed list before fetching JWKS
+  - Supports tokens from: `core-api`, `tatlock-ui`, `tatlock` OAuth applications
+  - Completes fix for environment endpoint user resolution
+
+### Removed
+
+- Deprecated `src/config.py` - consolidated to `src/shared/config.py`
+- Deprecated `src/security.py` - consolidated to `src/shared/security.py`
+
+## [1.10.6] - 2026-01-08
+
+### Fixed
+
+- **OIDC audience mismatch** - Accept tokens from multiple clients
+  - Changed `oidc_audience` (string) to `oidc_audiences` (list)
+  - Now accepts tokens with audience: `core-api`, `tatlock-ui`, or `tatlock`
+  - Fixes environment endpoint returning "default" user instead of authenticated username
+  - Fixed main.py to use `oidc_audiences[0]` for Swagger UI OAuth client
+
+### Changed
+
+- Documentation cleanup in README
+
+## [1.10.4] - 2026-01-07
+
+### Removed
+
+- **Ollama integration removed** - AI inference is no longer handled by this API
+  - Removed `src/models/ollama_client.py` and all Ollama-related configuration
+  - Removed `src/models/embeddings.py` and `src/models/embeddings_ollama.py`
+  - Removed model aliases and AI configuration from settings
+  - Health endpoints no longer check Ollama status
+  - Tests updated to reflect database-only health checks
+
+### Changed
+
+- Health check `/health/full` now only checks database connectivity
+- Diagnostics endpoint simplified (removed Ollama component info)
+
+## [1.10.3] - 2026-01-07
+
+### Fixed
+
+- **OIDC config not applied to domains module** - Both `src.auth.oidc` and `src.domains.auth.oidc` configs are now initialized
+  - Previously only `src.auth.oidc` was configured, leaving domains tools using hardcoded "local" user
+  - Environment endpoint now correctly uses authenticated user from OIDC token
+
