Release Management
Release management is the process of planning, coordinating, and executing software releases. It ensures that software is delivered reliably and predictably to users.
Release Process
+---------------------------------------------------------+
| RELEASE MANAGEMENT PROCESS |
+---------------------------------------------------------+
| |
| 1. Release Planning |
| - Define scope and features |
| - Set release date |
| - Identify risks |
| |
| 2. Code Freeze |
| - Stop adding new features |
| - Focus on bug fixes and stabilization |
| |
| 3. Testing & QA |
| - Regression testing |
| - Performance testing |
| - Security scanning |
| |
| 4. Release Candidate |
| - Create RC build |
| - Final round of testing |
| - Sign-off from stakeholders |
| |
| 5. Deployment |
| - Deploy to production |
| - Monitor for issues |
| - Have rollback plan ready |
| |
| 6. Post-Release |
| - Monitor metrics |
| - Collect feedback |
| - Plan next release |

Version Numbering
Semantic Versioning: MAJOR.MINOR.PATCH
MAJOR - Incompatible API changes
MINOR - New functionality (backward compatible)
PATCH - Bug fixes (backward compatible)
Examples:
1.0.0 - Initial release
1.1.0 - Added new feature
1.1.1 - Fixed a bug
2.0.0 - Breaking changes
Release Strategies
- Big Bang: All changes released at once — high risk
- Rolling: Continuous incremental releases
- Blue-Green: Two identical environments, swap traffic
- Canary: Release to small user group first, then expand
- Feature Flags: Toggle features without redeployment
Key Takeaways
- Release management reduces risk and improves predictability
- Semantic versioning communicates change scope clearly
- Always have a rollback plan for production deployments
- Post-release monitoring catches issues before users report them
