TL;DR
Updated Strategy: Patterns from Major OSS ProjectsAfter reviewing how Kubernetes, Node.js, Python, and Go manage releases, here is a refined strategy grounded in proven OSS practice. The Universal Rule Across All Major Projects
Recommendation for CAIPE: Branch ModelgitGraph
commit id: "feat: LiteLLM"
commit id: "feat: dynamic agents"
commit id: "feat: webex-bot"
branch release/0.3.x
checkout release/0.3.x
commit id: "tag: 0.3.0-rc.1" tag: "v0.3.0-rc.1"
commit id: "cherry-pick: fix slack warnings"
commit id: "tag: 0.3.0-rc.2" tag: "v0.3.0-rc.2"
commit id: "tag: 0.3.0" tag: "v0.3.0"
checkout main
commit id: "feat: 0.4.0 work starts"
checkout release/0.3.x
commit id: "cherry-pick: fix ui crash"
commit id: "tag: 0.3.1" tag: "v0.3.1"
checkout main
merge release/0.3.x id: "backport fixes to main"
Key rules (same as Kubernetes and Node.js):
Feature Freeze & Release Timelinegantt
title CAIPE Release Timeline (Kubernetes-style)
dateFormat YYYY-MM-DD
section main (0.3.x work)
Feature development :a1, 2026-02-01, 42d
Feature freeze (no new feat PRs to milestone) :milestone, 2026-03-14, 0d
section release/0.3.x
Cut branch + tag rc.1 :b1, 2026-03-14, 7d
Cherry-picks + tag rc.2 :b2, 2026-03-21, 7d
Final testing + tag 0.3.0 :b3, 2026-03-28, 7d
section Patches
0.3.1 0.3.2 as needed :c1, 2026-04-04, 30d
Cherry-Pick RC Strategy with GitHub ActionsThis is the mechanism Kubernetes uses with The iron rule (same across all major OSS):
Label-Driven Automation Flowflowchart TD
A[PR merged to main] --> B{cherry-pick label present?}
B -- "cherry-pick/release-0.3.x" --> C[GHA cherry-pick workflow triggers]
B -- No label --> D[Stays on main only]
C --> E{Cherry-pick applies cleanly?}
E -- Yes --> F[Bot opens PR to release/0.3.x]
E -- Conflict --> G[Bot comments conflict warning\non original PR]
F --> H[Reviewer merges to release/0.3.x]
G --> I[Author resolves manually]
H --> J{In RC window?}
J -- Yes --> K[Included in next RC tag]
J -- No, post-release --> L[Included in next patch 0.3.1]
