StellaOps Versioning

This document describes the versioning strategy for StellaOps releases.

Overview

StellaOps uses a two-tier versioning system:

  1. Suite Releases - Ubuntu-style calendar versioning (YYYY.MM) with codenames
  2. Module Releases - Semantic versioning (MAJOR.MINOR.PATCH)

Suite Versions (Ubuntu-style)

Format

YYYY.MM[-channel]
  • YYYY - Four-digit year
  • MM - Month (always 04 or 10)
  • channel - Optional: edge, stable, or lts

Examples

Version Codename Release Date Type Support
2026.04 Nova April 2026 LTS 5 years
2026.10 Orion October 2026 Feature 9 months
2027.04 Pulsar April 2027 LTS 5 years
2027.10 Quasar October 2027 Feature 9 months

Release Cadence

  • April releases (XX.04) - Long Term Support (LTS)

    • 5 years of security updates
    • 3 years of standard support
    • Recommended for production environments

  • October releases (XX.10) - Feature releases

    • 9 months of support
    • Latest features and improvements
    • Recommended for development and testing

Codenames

Codenames follow a celestial theme with alphabetical progression:

Letter Codename Celestial Object
N Nova Exploding star
O Orion Constellation
P Pulsar Rotating neutron star
Q Quasar Distant active galaxy
R Rigel Blue supergiant star
S Sirius Brightest star
T Triton Neptune's moon
U Umbra Shadow region
V Vega Fifth-brightest star
W Wezen Delta Canis Majoris

See codenames.md for the complete registry.

Module Versions (Semantic Versioning)

Format

MAJOR.MINOR.PATCH[-prerelease]

Following Semantic Versioning 2.0.0:

  • MAJOR - Incompatible API changes
  • MINOR - New functionality (backwards-compatible)
  • PATCH - Bug fixes (backwards-compatible)
  • prerelease - Optional: alpha.1, beta.2, rc.1

Examples
