Release Management Best Practices
Release management transforms completed development work into production-ready software that reaches users reliably. GitScrum's release tracking features help teams coordinate across milestones, track what's included in each release, and manage the handoff from development to deployment. The key is treating releases as planned events, not last-minute scrambles.
Release Strategies
| Strategy | Risk | Speed | Best For |
|---|---|---|---|
| Big Bang | High | Slow | Rare, major versions |
| Rolling | Medium | Medium | Continuous updates |
| Blue-Green | Low | Fast | Zero-downtime needed |
| Canary | Low | Medium | Risk-averse releases |
| Feature Flags | Low | Fast | Controlled rollouts |

Best Practices
- Automate deployment for consistency
- Use feature flags for controlled rollouts
- Have rollback plans for every release
- Monitor after deploy — don't assume success
- Communicate releases to all stakeholders
- Keep releases small for lower risk
- Document hotfix criteria to avoid abuse
- Learn from incidents to improve process
Anti-Patterns
✗ Manual deployments with no script
✗ No rollback capability
✗ "Big bang" releases with months of changes
✗ No monitoring after deployment
✗ Hotfixes without code review
✗ No communication to stakeholders
