-# Release Notes
-
-## Version 0.7.4 - Dec 5, 2025
-
-### 🪟 Windows Compatibility Fixes
-
-#### Test Suite Cross-Platform Support
-
-- **Fixed Git connector tests**: Resolved 9 test failures related to cross-platform path handling
-  - Fixed cross-drive relative path errors on Windows (e.g., `ValueError` when computing paths from C: to D:)
-  - Updated all test files to use `os.path.join()` with `temp_dir` instead of hardcoded Unix paths
-  - Enhanced `test_git_connector.py` with proper mocking for temp_dir-based paths
-- **Fixed pytest configuration conflicts**: Resolved root workspace test discovery issues
-
-  - Updated `pyproject.toml` to exclude `packages/` directory from root test collection
-  - Added `norecursedirs` to prevent conftest import conflicts between workspace and packages
-  - All 172 root workspace tests now pass without import errors
-
-- **Fixed config loader test isolation**: Prevented workspace config interference
-
-  - Added `monkeypatch.chdir(tmp_path)` to isolate tests from project root
-  - Tests no longer accidentally discover workspace `config.yaml` files
-
-- **Fixed website build system tests**: Resolved 19 failures/errors on Windows
-  - **Unicode encoding**: Added explicit `encoding="utf-8"` to all file operations
-  - **URL generation**: Used `Path.as_posix()` for cross-platform sitemap URLs
-  - **Windows path handling**: Implemented smart colon detection to distinguish drive letters (`C:`) from source:dest syntax
-  - **File cleanup**: Added retry logic with delays for Windows file handle cleanup (fixes 15 `PermissionError` cases)
-  - **Test assertions**: Updated timing assertions from `> 0` to `>= 0` for edge case compatibility
-
-#### Technical Improvements
-
-- **Cross-platform best practices**: All fixes use Python standard library APIs (`os.path.join()`, `Path.as_posix()`, explicit encoding)
-- **Full backward compatibility**: No breaking changes for Mac/Linux platforms
-- **Comprehensive test coverage**: All 1899+ tests passing on Windows (172 root + 33 git + 120 website + 1674 loader)
-
-## Version 0.7.3 - Sept 11, 2025
-
-### Logging System Fixes
-
-- **Fixed logging duplication**: Resolved CLI commands printing each log message 2-4 times due to multiple handler setup calls
-- **Unified logging architecture**: Centralized logging configuration across all packages with idempotent setup and new `reconfigure()` method
-
-## Version 0.7.2 - Sept 05, 2025
-
-### Release Process Enhancements
-
-- Internal inter-package dependencies are now pinned to the unified release version to prevent mismatched installs when only one package is upgraded.
-- Dry-run output enhanced: previews internal dependency pin changes per package and uses the new version for tag and release previews.
-- Enforced, explicit release order: bump versions → update classifiers → pin internal deps → commit & push → tag → release.
-- Updated commit messages to reflect classifier and internal dependency updates.
-
-## Version 0.7.1 - Sept 04, 2025
-
-### LLM Provider-Agnostic Configuration & Migration
-
-- BETA: Added Azure OpenAI support (no more 404s from misconfigured endpoints) and robust Ollama endpoint handling
-- Introduced unified `global.llm.*` configuration controlling provider, `base_url`, models, tokenizer, request policy, rate limits, and `embeddings.vector_size`.
-- Legacy fields (`global.embedding.*` and `file_conversion.markitdown.*`) remain supported with deprecation warnings; migration is recommended.
-- Vector size is now read from config; hardcoded `1536` defaults replaced with config-driven values and a deprecated fallback warning when unspecified.
-- Structured logging added for LLM requests (provider, operation, model, latency; secrets redacted) and normalized exception mapping across providers.
-- Documentation updated with the new schema and env vars:
-  - Azure logs label provider as `azure_openai`; OpenAI as `openai`; Ollama logs include latency for chat.
-  - Clear error when Azure `base_url` includes `/openai/deployments/...`; requires `api_version`.
-  - Ollama auto-detects `/v1` vs native. Native tries batch `/api/embed` first, falls back to `/api/embeddings`.
-- Documentation updated with the new schema and env vars:
-  - Configuration reference: `docs/users/configuration/config-file-reference.md`
-  - Environment variables: `docs/users/configuration/environment-variables.md`
-
-### Massive Codebase Refactor
-
-- Centralized LLM layer in `qdrant-loader-core` with provider adapters (OpenAI / OpenAI-compatible via `base_url`, Ollama native or `/v1`).
-- Removed direct OpenAI imports from application code; apps now use a provider factory from the core package.
-- MCP server now prefers config file loading with CLI/env/file precedence and redacted `--print-config`; legacy env-only mode warns.
-- Replaced hardcoded vector-size usage across components with configuration-driven values.
-- Updated tests and documentation to align with provider-agnostic architecture.

-  - **Root cause**: Invalid regex pattern `r"^[|-\s:]+$"` in `_split_excel_sheet_content` method
-  - **Solution**: Escaped dash character to create valid pattern: `r"^[|\-\s:]+$"`
-  - **Impact**: Excel files no longer fall back to default chunking strategy
-- **Fixed large table chunking logic**: Resolved issue where large Excel tables were treated as single massive chunks
-  - **Problem**: 128K character files created only 2-5 chunks instead of ~200 chunks at 600-character limit
-  - **Root cause**: Large logical units (tables) were not split when exceeding max_size
-  - **Solution**: Added intelligent splitting logic that preserves table structure while respecting chunk size limits
-  - **Result**: Large Excel files now properly chunk into appropriate sizes (e.g., 74K chars → 127 chunks @ ~588 chars each)
-- **Eliminated token limit warnings**: Fixed the `Content exceeds maximum token limit, truncating` warnings that occurred with large Excel chunks

+# Best Practices for qdrant-loader
+
+> **Author:** nguyen.vu@cbtw.tech
+
+This guide outlines Pythonic patterns and AI engineering best practices for the qdrant-loader project.
+
+## 1. Pythonic Code Standards
+
+### 1.1. Avoid Class-Level Anti-Patterns
+
+- **No Redundant `__new__`**: Do not override `__new__` unless you are implementing a strict Singleton or working with immutable types. Standard service initialization belongs in `__init__`.
+- **Explicit over Implicit**: Avoid "monkey-patching" (e.g., overwriting a local class with one from another package via try/except). Use explicit dependencies.
+
+### 1.2. Type Hinting & Structural Subtyping
+
+- **Protocols over Base Classes**: Use `typing.Protocol` for defining interfaces (e.g., `ChunkingStrategy`). This follows the "Go-style" duck typing which is more flexible for a plugin-based architecture.
+- **Pydantic for Data/Config**: Use Pydantic models for all data structures and configuration. Avoid passing around raw dictionaries.
+
+### 1.3. Dependency Injection (DI)
+
+**Granular Injection**: Do not pass the entire `Settings` or `GlobalConfig` object to every service. Pass only the specific sub-config or primitives the service needs. This makes unit testing significantly easier.
+
+```python
+# BAD: Monolithic config passing
+def __init__(self, settings: Settings):
+    self.chunk_size = settings.global_config.chunking.chunk_size
+
+# GOOD: Granular injection
+def __init__(self, chunk_size: int, overlap: int):
+    self.chunk_size = chunk_size
+```
+
+## 2. AI & RAG Best Practices
+
+### 2.1. Metadata Hygiene
+
+- **Strict Schemas**: Every document ingested must have a consistent metadata schema. If a new field is added, update the Document model and relevant extractors.
+- **Provenance**: Always preserve the "source of truth" (URL, file path, line number) in metadata to enable high-quality citations in the RAG retrieval phase.
+
+### 2.2. Embedding Drift Management
+
+- **Versioned Collections**: If you change the embedding model (e.g., moving from OpenAI `text-embedding-3-small` to `3-large`), you must create a new Qdrant collection. Vectors are not compatible across different models or dimensions.
+
+### 2.3. Evaluation-First Development
+
+**Ragas/G-Eval**: Before merging a change to the `HybridSearchEngine` or `Reranker`, run an evaluation suite. Aim for improvements in:
+
+- **Faithfulness**: The answer is derived only from context.
+- **Answer Relevance**: The answer directly addresses the query.
+- **Context Precision**: The retrieved documents are relevant.
+
+## 3. Architecture & Monorepo Management
+
+### 3.1. Package Isolation
+
+- **Core is Sacred**: `qdrant-loader-core` should have zero dependencies on `qdrant-loader` or `qdrant-loader-mcp-server`. It is the foundational abstraction layer.
+- **Circular Dependencies**: Use `from __future__ import annotations` and local imports inside methods if absolutely necessary to break circular loops, but prefer refactoring to a shared utility.
+
+### 3.2. Logging & Observability
+
+- **Centralized Logging**: Use the `LoggingConfig` from core. Do not initialize standard `logging.getLogger(__name__)` manually if you need structured logs.
+- **Traceability**: Every MCP request should have a unique `request_id` passed through the search engine to help debug multi-step retrieval chains.
+
+## 4. Testing Standards
+
+### 4.1. Mocking External APIs
+
+- **No Real LLM Calls in Unit Tests**: Always use `unittest.mock` or `pytest-mock` to stub LLM providers. Use the `_NoopProvider` in core as a base for mocks.
+- **VCR.py / Pytest-Recording**: For integration tests, use VCR-style recording to capture and replay real Qdrant/LLM interactions to ensure deterministic test results.
+
+### 4.2. Algorithmic Validation
+
+- **Similarity Thresholds**: When testing search tools, include cases that specifically check the "boundary" of your similarity thresholds (e.g., verifying a 0.69 score is excluded if the threshold is 0.7).
+
+## 5. Summary Checklist
+
+For reviewer to recheck everytime a PR comes up:
+
+- [ ] Is the PR code type-hinted and linted?
+- [ ] Did it avoid redundant class overrides like `__new__`?
+- [ ] Are services using granular dependency injection?
+- [ ] If the commiter modified the retrieval logic, did they run a RAG evaluation?
+- [ ] Are PR's new logs structured and redact-protected?

-    All packages will always have the same version number. The qdrant-loader

+    When invoked with sync_versions=True the command only synchronizes all package versions, development-status classifiers, and internal dependency pins to the qdrant-loader package version and then exits. In normal mode it performs repository and CI checks, prompts for a version bump (major/minor/patch/beta/custom), validates CHANGELOG.md, applies the version and classifier updates, pins internal dependencies, commits and pushes changes, creates annotated tags for each releasable package, and creates GitHub releases. Use dry_run=True to simulate all steps without making any persistent changes; use verbose=True to enable more detailed logging.
