Tracking issue for the **Ryax 26.10.0** release. The process is the [release how-to](https://gitlab.com/groups/ryax-tech/-/wikis/3-Release/howto-release). Every row below is delivered by MRs merged since **26.9.0** (2026-09-10), into a service's `master` or into `ryax-engine`'s `release-26.10.0` branch. **RC** is the first release candidate that contains the change; *next* means merged but not in an RC yet. ## New features | Issue | MRs | RC | |---|---|---| | #1421 Better GPU representation in Ryax | ryax-tech/ryax/ryax-core!498, ryax-tech/ryax/ryax-core!510, ryax-tech/ryax/ryax-engine!81, ryax-tech/ryax/ryax-engine!82, ryax-tech/ryax/ryax-intelliscale!33, ryax-tech/ryax/ryax-repository!286, ryax-tech/ryax/ryax-studio!495 | rc0 | | #1458 Key IntelliScale recommendations by hardware, not by site | ryax-tech/ryax/ryax-core!500, ryax-tech/ryax/ryax-core!501, ryax-tech/ryax/ryax-intelliscale!33, ryax-tech/ryax/ryax-intelliscale!34 | rc0 | | #1469 Flat GPU catalog with search, and a root /node-pools endpoint with filters | ryax-tech/ryax/ryax-core!505 | rc0 | | #1423 Default password should be random | ryax-tech/ryax/ryax-core!497, ryax-tech/ryax/ryax-engine!76, ryax-tech/ryax/ryax-engine!77, ryax-tech/ryax/ryax-front!174 | rc0 | | #1471 MinIO replaced by versitygw, with an upgrade-time copy, an optional pre-copy and a decommission command | ryax-tech/ryax/ryax-engine!98, ryax-tech/ryax/ryax-engine!99 | rc1 | | #1320 Migrate away from Bitnami Helm charts.

Closes when `release-26.10.0` merges into `master`. | ryax-tech/ryax/ryax-engine!95 | rc0 | Closed after verification, with no fix in this release: #1269, #1305. ## Release candidates Built from `release-26.10.0`. Multi-arch images on `docker.io/ryaxtech` and `registry.ryax.org/release`; charts `ryax-engine`, `ryax-worker-k8s` and `ryax-worker-slurm-ssh` in `oci://registry.ryax.org/release-charts`. | RC | Tagged | Outcome | |---|---|---| | rc0 | 2026-10-06 | Not deployed: arm64 builds timed out on CI defaults, fixed by `ci_common` 8.3.0. | | rc1 | 2026-10-06 | Staging: the new broker blocked every publisher (default free-disk limit above its volume). | | rc2 | 2026-10-06 | Staging OK. The worker's PostgreSQL was OOM-killed draining the backlog (#1477). | | rc3 | 2026-10-23 | Staging: found #1481, #1482, #1483. | | rc4 | 2026-10-26 | Staging OK, #1481 and #1482 confirmed fixed. | | rc5 | 2026-10-26 | Staging: found #1485. | | rc6 | 2026-10-26 | Brings the #1485 fix. | | rc7 | 2026-10-29 | Brings #1477 (worker), #1483, #1490, #1491. Staging OK: every Ryax image on rc7, queues drained, node pool `architecture` lowercase, archived pool answers 404, two "Run once" deploys in a row both completed and stopped gracefully. | | **26.10.0** | 2026-10-29 | Tagged from the rc7 commits. | Staging is backed up with `pg_dumpall` before each upgrade (`backups/pre-<version>.sql.gz` on the datastore volume). MinIO and the old broker volume are decommissioned, so a rollback to 26.9.0 needs the database dump plus a filestore backup. ## Remaining before 26.10.0 - [x] Bump core and front for ryax-tech/ryax/ryax-core!527, ryax-tech/ryax/ryax-core!528 and ryax-tech/ryax/ryax-front!185 (#1483, #1477), cut the next RC, deploy it on staging, and rerun the node pool recipes and a "Run once" followed by a redeploy. - [x] #1492 (archiving a node pool and pinned actions) postponed to a later release; RELEASE.md describes the current behaviour and the order to follow. #1493 (worker falls back to its first pool), #1494 (memory field message) and #1495 (`GET /sites/{id}` lists archived node pools) also come later. - [ ] Merge ryax-tech/ryax/ryax-engine!104 (CI only). - [x] Test the local install from the README (k3s, minimal values, worker registration): done 2026-10-29 on rc7 with `docker compose`. Engine in 9 min, worker, default-actions built, a "Run once" → "Print Environment" workflow completed. The README's node pool API example was rejected with a 422 (no `architecture`, old `gpu` field); fixed on `release-26.10.0` (8931a69). - [x] Cut `26.10.0`: done 2026-10-29. - [x] Merge `release-26.10.0` into `master`: ryax-tech/ryax/ryax-engine!103 merged 2026-10-29 as a merge commit (7640e6e); `git describe origin/master` gives `26.10.0-3-g7640e6e`. #1462 did not close by itself. - [x] GitLab and GitHub releases: https://gitlab.com/ryax-tech/ryax/ryax-engine/-/releases/26.10.0, https://github.com/RyaxTech/ryax-engine/releases/tag/26.10.0 - [ ] Announcements (Cliq, Discord, Slack).
