Highlights

Support for rustls's aws-lc-rs is available under a new kube/aws-lc-rs feature. Via #1568 for #1562

Furthermore, there are features to help avoid dynamic typing:

1. Added a DeserializeGuard safety wrapper to lift deserialisation errors (to e.g. not break watchers). See the errorbound example and core module module. Wrapped type be used with e.g. Api::<DeserializeGuard<CaConfigMap>>. Via #1556
2. A derive macro for Resource; #[derive(Resource)] allows inheriting existing k8s-openapi resource implementations to avoid stepping down to the dynamic api. See the cert check example for usage. Via #1565

Added

• Add error boundary wrapper type by @nightkr in #1556
• Implement Error for error_boundary::InvalidObject by @nightkr in #1558
• Add finalizers predicate filter by @ivan-kiselev in #1560

Highlights

Better query validation, better client header customisation, and two new modules:

Bugfix Release

This release fixes #1524; a regression from 0.92.0 causing watcher to skip pages on initial list. See #1525.

It is recommended to upgrade from 0.92.0.

Runtime: Decreased Memory Usage from watcher

Buffering of initial pages / init streams is no longer a mandatory process with watcher::Event gaining new Init, InitApply, and InitDone events. These events are read on the store side maintaining the atomicity/completeness guarantees for reflector and Store users.

This constitutes a significant memory decrease for all watcher users, and it has more details in a new kube.rs/blog post.

The downside is a breaking change to watcher::Event. Plain usage of watcher / reflector / Controller should generally not need to change anything, but custom stores / matches on watcher::Event will need an update. If you are writing custom stores, the new signals should be helpful for improved caching.

Thanks to @fabriziosestito via Kubewarden for #1494 . Follow-ups for this feature: #1499 and #1504.

Client: HTTP Proxy Support

Support is now introduced under the http-proxy feature pulling in hyper-http-proxy complementing the already existing socks5 proxy feature.

Thanks to @aviramha via MetalBear for the support in #1496, with follow-ups #1501 + #1502

• Added support for HTTP proxy with hyper-proxy2 by @aviramha in #1496
• Implement client native object reference fetching by @Danil-Grigorev in #1511

• Align watcher::Event init/page variants by @clux in #1504
• Update json-patch to 2.0.0 by @bobsongplus in #1507

Fixed

• Fix potentially panicing unchecked duration adds in runtime by @clux in #1489
• ObjectList now accepts null metadata like upstream k8s does by @aviramha in #1492
• rename http_proxy feature to http-proxy and add it to the umbrella crate by @aviramha in #1501

Kubernetes v1_30 support via k8s-openapi 0.22

Unstable Stream Sharing

A more complete implementation that allows sharing watcher streams between multiple Controllers (for #1080) has been added under the unstable-runtime feature-flag in #1449 and #1483 by @mateiidavid. This represents the first usable implementation of shared streams (and replaces the older prototype part in #1470). While some changes are expected, you can check the shared_stream_controller example for a high-level overview.

What's Changed

Added

• Add shared stream interfaces by @mateiidavid in #1449
• Allow to create non-controller owner reference for resource by @Danil-Grigorev in #1475
• feat(runtime): support for owned shared streams by @mateiidavid in #1483

Changed

• Upgrade k8s-openapi to 0.22 and bump MK8SV to 1.25 by @clux in #1485

Removed

• Remove abandoned StreamSubscribe implementation by @clux in #1470

Fixed

• Include inner error message in Display for SerdeError by @XAMPPRocky in #1481
• Remove invalid uniqueItems property from CRDs when Sets are used by @sbernauer in #1484
