Release Management

This document outlines the standards and best practices for release management across all Bayat projects.

Versioning Scheme

Semantic Versioning (SemVer)

All Bayat projects must follow semantic versioning guidelines in the format of MAJOR.MINOR.PATCH:

  • MAJOR: Incompatible API changes
  • MINOR: Backwards-compatible functionality additions
  • PATCH: Backwards-compatible bug fixes

Examples:

  • 1.0.0 - Initial stable release
  • 1.1.0 - New features added
  • 1.1.1 - Bug fixes

Pre-release Identifiers

For pre-release versions, use the following identifiers:

  • alpha - Early testing, unstable
  • beta - Feature complete, potentially unstable
  • rc - Release candidate, feature frozen

Examples:

  • 1.0.0-alpha.1
  • 1.0.0-beta.2
  • 1.0.0-rc.1

Release Cycle

Standard Release Cycle

  1. Development phase (feature branches)
  2. Integration phase (merge to develop)
  3. Stabilization phase (create release branch)
  4. Release candidate testing
  5. Production release (merge to main/master)
  6. Post-release maintenance

Release Timeframes

  • Major releases: Every 6-12 months
  • Minor releases: Every 1-3 months
  • Patch releases: As needed, typically within 1-2 weeks of bug discovery

Release Process

Pre-Release Checklist

  • All tests passing on CI/CD pipeline
  • Code review completed
  • Documentation updated
  • Release notes prepared
  • Security scan completed
  • Performance tests passed
  • Accessibility compliance verified
  • Localization completed

Release Notes

Release notes must include:

  • Version number and release date
  • Summary of changes
  • New features (for minor and major releases)
  • Bug fixes with reference to issue IDs
  • Breaking changes with migration guide
  • Dependencies updated
  • Deprecation notices
  • Contributors acknowledgment

Release Artifacts

  • Source code tags in repository
  • Compiled binaries/packages
  • Docker images
  • Documentation updates
  • Deployment manifests

Deployment Stages

Environments

  • Development
  • Testing/QA
  • Staging
  • Production

Rollout Strategy

  • Canary deployments for high-risk changes
  • Blue/green deployments for zero-downtime updates
  • Progressive rollout for user-facing changes

Rollback Procedures

Rollback Triggers

  • Critical security vulnerabilities
  • Data corruption issues
  • Significant performance degradation
  • Feature regression affecting core functionality

Rollback Process

  1. Identify the need for rollback
  2. Communicate to stakeholders
  3. Deploy previous stable version
  4. Verify system stability
  5. Analyze failure and document lessons learned

LTS (Long-Term Support) Policy

  • LTS releases are designated for production use
  • Supported for a minimum of 12 months
  • Security updates provided for entire support period
  • No new features added to LTS releases

Archiving Policy

  • End-of-life notification 3 months before support ends
  • Archive repository with clear EOL notice
  • Provide migration path to supported versions

Communication

Stakeholder Notification

  • Advance notice for major releases (1 month)
  • Release announcement emails
  • Change log published on relevant platforms
  • Deprecation notices (3 months before removal)

Release Calendar

  • Maintain a public release calendar
  • Communicate schedule changes at least 2 weeks in advance
