+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.2.1] - 2025-11-11
+
+### Removed
+- **BREAKING**: Removed `phate` dependency from install_requires
+  - PHATE was only used in docstring examples, not in actual code
+  - Reduces dependency conflicts and installation complexity
+- **BREAKING**: Removed `scprep>=1.0` dependency from install_requires  
+  - SCPREP was only used for an unused decorator that has been removed
+  - Import statement removed from `tphate/mds.py`
+
+### Changed
+- Updated `requirements.txt` to remove `phate` dependency for consistency
+- Updated `examples/usage.ipynb` with cleaned dependency list
+- Updated unit test version assertion from '0.1.0' to '1.2.0'
+
+### Added
+- Added `__version__` export to `tphate/__init__.py` for proper version access
+- Added comprehensive dependency verification in example notebook
+
+### Fixed
+- Fixed version accessibility issue - `tphate.__version__` now works correctly
+- Ensured all core functionality works without removed dependencies
+
+### Dependencies
+**Before (13 dependencies):**
+- statsmodels>=0.13.5, pytest>=7.2.1, numpy>=1.16.0, scipy>=1.1.0, 
+- scikit-learn>=0.24, tasklogger>=1.0, graphtools>=1.5.3, matplotlib>=3.0,
+- s_gd2>=1.8.1, pygsp, Deprecated, **phate**, **scprep>=1.0**
+
+**After (11 dependencies):**
+- statsmodels>=0.13.5, pytest>=7.2.1, numpy>=1.16.0, scipy>=1.1.0,
+- scikit-learn>=0.24, tasklogger>=1.0, graphtools>=1.5.3, matplotlib>=3.0,
+- s_gd2>=1.8.1, pygsp, Deprecated
+
+### Technical Details
+- **Reduction**: 15% fewer dependencies (13 → 11 packages)
+- **Compatibility**: 100% backward compatible for core functionality
+- **Testing**: All existing functionality verified working
+- **Performance**: Faster installation, fewer potential conflicts
+
+### Files Modified
+- `setup.py` - Removed phate and scprep from install_requires
+- `requirements.txt` - Removed phate dependency  
+- `tphate/__init__.py` - Added __version__ export
+- `tphate/mds.py` - Removed unused scprep import
+- `test/test_tphate.py` - Updated version assertion
+- `examples/usage.ipynb` - Updated with cleaned dependencies
+
+### Migration Notes
+This is a **breaking change** only for code that directly imported `phate` or `scprep` 
+expecting them to be available through TPHATE's dependencies. Core TPHATE functionality 
+remains 100% compatible.
+
+If your code requires PHATE or SCPREP, install them separately:
+```bash
+pip install phate scprep
+```

+# TPHATE Pip Distribution Update Guide
+
+This guide provides step-by-step instructions for updating the TPHATE package on PyPI after the dependency cleanup changes.
+
+## Prerequisites
+
+1. **Accounts & Access**
+   - PyPI account with upload permissions for the TPHATE package
+   - TestPyPI account for testing (recommended)
+
+2. **Tools Installation**
+   ```bash
+   pip install --upgrade pip setuptools wheel twine
+   ```
+
+3. **Authentication Setup**
+   ```bash
+   # Configure PyPI credentials (one-time setup)
+   # Option 1: Use API tokens (recommended)
+   # Create API tokens at https://pypi.org/manage/account/token/
+   
+   # Option 2: Use ~/.pypirc file
+   cat > ~/.pypirc << EOF
+   [distutils]
+   index-servers =
+       pypi
+       testpypi
+   
+   [pypi]
+   repository = https://upload.pypi.org/legacy/
+   username = __token__
+   password = pypi-YOUR_API_TOKEN_HERE
+   
+   [testpypi]
+   repository = https://test.pypi.org/legacy/
+   username = __token__
+   password = pypi-YOUR_TEST_API_TOKEN_HERE
+   EOF
+   ```
+
+## Pre-Release Checklist
+
+- [ ] All tests pass: `python -m pytest test/ -v`
+- [ ] Version updated in `tphate/version.py` (currently 1.2.1)
+- [ ] Changelog updated with release notes
+- [ ] Dependencies verified in `setup.py` (11 total, phate & scprep removed)
+- [ ] Clean workspace (no build artifacts)
+
+## Release Process
+
+### Step 1: Clean Build Environment
+```bash
+cd /Users/elb/Desktop/code_packages_maintainer_version/TPHATE/TPHATE
+
+# Remove any existing build artifacts
+rm -rf build/ dist/ *.egg-info/ .pytest_cache/
+find . -name "*.pyc" -delete
+find . -name "__pycache__" -type d -delete
+```
+
+### Step 2: Create Distribution Packages
+```bash
+# Activate virtual environment if needed
+source test_env/bin/activate
+
+# Build source distribution and wheel
+python setup.py sdist bdist_wheel
+
+# Verify the build
+ls -la dist/
+```
+
+Expected output:
+```
+tphate-1.2.1.tar.gz      # Source distribution
+tphate-1.2.1-py3-none-any.whl  # Universal wheel
+```
+
+### Step 3: Test the Distribution (Optional but Recommended)
+
+#### Upload to TestPyPI First
+```bash
+# Upload to TestPyPI
+twine upload --repository testpypi dist/*
+
+# Test installation from TestPyPI
+pip install --index-url https://test.pypi.org/simple/ tphate==1.2.1
+
+# Verify the test installation
+python -c "import tphate; print('Version:', tphate.__version__)"
+```
+
+### Step 4: Upload to Production PyPI
+```bash
+# Upload to production PyPI
+twine upload dist/*
+```
+
+### Step 5: Verify Production Release
+```bash
+# Test installation from production PyPI
+pip install --upgrade tphate
+
+# Verify installation
+python -c "
+import tphate
+import numpy as np
+
+print('✅ TPHATE Version:', tphate.__version__)
+
+# Quick functionality test
+data = np.random.randn(50, 10)
+tphate_op = tphate.TPHATE(n_components=2, verbose=False)
+embedding = tphate_op.fit_transform(data)
+print('✅ Embedding shape:', embedding.shape)
+print('✅ Dependencies reduced: phate & scprep removed')
+print('✅ Release verification complete!')
+"
+```
+
+## Post-Release Tasks
+
+### 1. Update Repository Tags
+```bash
+# Tag the release
+git add .
+git commit -m "Release v1.2.1: Remove unnecessary PHATE/SCPREP dependencies"
+git tag -a v1.2.1 -m "Version 1.2.1 - Dependency cleanup"
+git push origin main --tags
+```
+
+### 2. Update Documentation
+- [ ] Update GitHub README if needed
+- [ ] Update documentation site (if applicable)
+- [ ] Notify users of breaking changes (if applicable)
+
+### 3. Monitor Release
+- [ ] Check PyPI package page: https://pypi.org/project/tphate/
+- [ ] Monitor download statistics
+- [ ] Watch for user feedback or issues
+
+## Rollback Procedure (if needed)
+
+If issues are discovered after release:
+
+```bash
+# Option 1: Quick patch release
+# 1. Fix the issue
+# 2. Increment version (e.g., 1.2.2)
+# 3. Follow release process above
+
+# Option 2: Yank the problematic release (removes from new installs)
+# This can only be done through PyPI web interface:
+# https://pypi.org/manage/project/tphate/releases/
+```
+
+## Key Changes in v1.2.1
+
+**Removed Dependencies:**
+- `phate` - Only used in docstring examples
+- `scprep>=1.0` - Only used for unused decorator
+
+**Benefits:**
+- 15% fewer dependencies (13 → 11 packages)
+- Faster installation
+- Fewer potential conflicts
+- Cleaner dependency tree
+
+**Migration for Users:**
+If users need PHATE or SCPREP functionality:
+```bash
+pip install tphate phate scprep
+```
+
+## Troubleshooting
+
+**Common Issues:**
+
+1. **Twine authentication errors:**
+   - Verify API tokens are correct
+   - Check ~/.pypirc configuration
+
+2. **Version conflicts:**
+   - Ensure version in `setup.py` matches `tphate/version.py`
+   - Check that version doesn't already exist on PyPI
+
+3. **Build errors:**
+   - Verify all dependencies are installed
+   - Check `setup.py` syntax
+   - Ensure Python version compatibility
+
+4. **Upload permission errors:**
+   - Verify PyPI account has upload permissions for TPHATE
+   - Check if you're a maintainer of the project
