Highlights

List/Watch Changes

One big change is the splitting of ListParams into ListParams and WatchParams in #1162 and #1171. If you were using api.list directly, this should not affect you, but api.watch calls will need a replace of ListParams to WatchParams. Apart from the resulting field splitting, the two structs still have a mostly compatible api.

If you were passing ListParams to watcher or Controller, you can change this for a new watcher::Config with a mostly compatible interface:

-    let stream = watcher(api, ListParams::default());
+    let stream = watcher(api, watcher::Config::default());

The reason for this change has been to add support for specific version match strategies and has new builders on both ListParams and watcher::Config to control the strategy. Using the new VersionMatch::NotOlderThan can reduce strain on the apiserver for individual api.list calls. Watchers will benefit the most from this, and should consider using the semantic Any strategy (= NotOlderThan with version "0") on all relists by setting watcher::Config::any_semantic().

rustls

This release closes all our rustls issues as a consequence of the long standing IP address incompatibility (#153) having been resolved upstream. All rustls specific overrides (such as using the deprecated incluster_dns strategy for configuration #1184) have been removed as a result.

Controller streams

Multiple new runtime features have been added to be able to more precisely control the input streams used by Controller a starting step towards stream sharing (#1080) and as a way to reduce excess input events. Because these interfaces are likely to remain in flux for some time, these are only available under unstable feature flags.
