+- **Restored Python 3.10 support** - Re-added compatibility with Python 3.10 as it remains actively supported until October 2026
+- Updated test matrix to include Python 3.10 with Sphinx 6, 7, and 8
+- Test matrix now covers 11 combinations (excludes Python 3.13 + Sphinx 6 due to deprecation warnings)
+- **Note**: Python 3.10 is limited to Sphinx 8.1.x (max 8.1.3) due to Sphinx 8.2+ requiring Python >=3.11. This is handled automatically in the test configuration.
+- Updated codecov integration to use Python 3.12 + Sphinx 8 baseline

+# Release v1.1.1
+
+**Release Date**: October 23, 2025
+
+This is a patch release that restores Python 3.10 compatibility while maintaining support for newer Python versions.
+
+## 👌 Improvements
+
+### Python 3.10 Support Restored
+
+Python 3.10 support has been re-added to the project. Python 3.10 remains actively supported until October 2026, making it an important version to maintain compatibility with.
+
+**Key details:**
+- Python 3.10 is now fully supported alongside Python 3.11, 3.12, and 3.13
+- All existing features work identically across all supported Python versions
+- Comprehensive test coverage ensures compatibility
+
+### Technical Implementation
+
+**Version-Specific Sphinx Constraints:**
+- Python 3.10 is limited to **Sphinx 8.1.x** (maximum 8.1.3)
+- Python 3.11+ continues to use **Sphinx 8.2+** as normal
+- This constraint exists because Sphinx 8.2.0+ requires Python >=3.11
+
+The test infrastructure automatically handles these version-specific requirements, ensuring correct behavior across all combinations.
+
+### Test Matrix Updates
+
+**Supported Combinations:**
+- Python 3.10, 3.11, 3.12: Sphinx 6, 7, 8
+- Python 3.13: Sphinx 7, 8
+
+**Total: 11 test environments** (excludes Python 3.13 + Sphinx 6)
+
+Python 3.13 + Sphinx 6 was excluded because Sphinx 6.2.1 generates 1870+ deprecation warnings on Python 3.13 due to its use of deprecated `datetime.utcfromtimestamp()`. This is an unlikely real-world combination.
+
+### CI/CD Improvements
+
+- Updated GitHub Actions CI matrix to include Python 3.10
+- Configured codecov to use Python 3.12 + Sphinx 8 as baseline
+- Implemented tokenless codecov uploads for public repository
+- Added version-specific test fixtures for Sphinx 8.1 vs 8.2+ compatibility
+
+## 📦 Installation
+
+Install or upgrade via pip:
+
+```bash
+pip install --upgrade sphinx-exercise
+```
+
+## 🔄 Migration Notes
+
+**If you're upgrading from v1.1.0:**
+- No breaking changes
+- No action required
+- Python 3.10 users can now upgrade safely
+
+**If you're on Python 3.10:**
+- You can now use sphinx-exercise v1.1.1
+- Sphinx 8 support is limited to 8.1.x on Python 3.10
+- All features work identically to newer Python versions
+
+## 🐛 Bug Fixes
+
+- Fixed test fixtures to handle Sphinx 8.1.x vs 8.2+ XML output differences
+- Ensured consistent test behavior across all Python/Sphinx combinations
+
+## 📝 Full Changelog
+
+For complete details, see the [CHANGELOG.md](https://github.com/executablebooks/sphinx-exercise/blob/main/CHANGELOG.md).
+
+## 🙏 Acknowledgments
+
+Thank you to all contributors and users who reported the need for Python 3.10 support!
