| Event | When (time before release) | What happens | |||
|---|---|---|---|---|---|
| science feature freeze for simulations | 24 21 months before | All PRs for features intended to be released and used in associated simulations posted on github. Must be complete and ready to integrate. After integrations are complete, make first alpha tag and start component-level, "standalone" tuning. | |||
| Component tuning completed; coupled tuning begins | 19 18 months before | All component level tuning must be done. Atmosphere-only cases, ocean-only, land-only, etc. All input files that will be needed for coupled runs finished and on input data server. Open PRs to add final tuning values/changes. | Coupled runs begin | 18 months before | Coupled simulations begin. The After PRs are integrated, begin coupled tuning. Make first beta tag. After this, the compsets used in thecoupled simulations must stay bit-for-bit to any changes until release is madeexcept for bug fixes, tuning updates. |
| Coupled tuning completed; coupled runs begins | 15 months before | Start the coupled simulations to be included with release. | |||
| All-science freeefreeze | 1 month before | Any science code changes to be in release must have their PR merged to master by this date. Non-science config/performance changes still allowed. | |||
| Code Freeze | 1 week before | No changes to any executed code. May still update README's and other documentation. Conduct final tests. Get DOI | |||
| vX.Y.0 tag made on master. | The release | New climate-changing PRs can be merged to master after this. Maintenance branch for release made. | |||
