WARNING: The changes are backward-compatible (in theory). But the changes are also massive, so things can break unexpectedly (in practice). Test this upgrade carefully.

New features:

  • @kopf.daemon for background resource-accompanying tasks/threads. #330 #342 #360
  • @kopf.timer for regular and/or delayed activities & checks. #330 #342 #360
  • kopf.PRESENT for labels/annotations filters (instead of misleading None). #327
  • kopf.ABSENT for labels/annotations filters. #327
  • Arbitrary callbacks for labels/annotations filters. #328
  • kopf.all_(), kopf.any_(), kopf.not_(), kopf.none_() helpers for callbacks aggregation. #345
  • A proper official documented way to configure operators; plus docs. #336 #337 #331
  • Identities of operators, allowing multiple non-colliding operators for the same resources. #331 #344
  • Configurable client-side timeouts for watch requests. #322 #336
  • Configurable storages for handling state & diff-bases. #331 #346 #353

Improvements:

  • Internal instant functions (lifecycles, when-filters) do not use thread pools anymore. #326
  • Bodies & patches now have magical properties for metadata, spec, status, with "live view" into data. #327
  • Labels and annotations are passed as additional kwargs (similar to body/spec/meta/status). #327
  • All user-facing types and classes are published as framework's public interface (via top-level package). #341
  • Switch KopfExample & KopfPeering from v1beta1 to v1 CRD API; keep v1beta1 nearby. #364
  • Documentation is restructured for separate pages for all aspects of handling (kwargs, filters, etc). #325
  • Explain the "structural schemas" of K8s 1.16+, and v1-vs-v1beta1 CRD differences. #364

Fixes:

  • Threads from the sync handlers executors are not leaked (not left orphaned) at exit. #326
  • Handlers' state is now persisted in annotations, not in status: for custom & built-in resources. This solves the issues with built-ins not handled properly in K8s 1.16+. #331
  • Fix the on-field handler not being invoked when the diff is too generic (relative to the field). #340
  • Provoke after-sleep handling cycles even on resources with no arbitrary field preservation. #343
  • Fix premature finalizer removal with 2+ deletion handlers. #361
  • Avoid no-effect patching and potentially delaying handling cycles. #362

Internal changes:

  • Coveralls is made optional. #363
  • Compatibility with Kubernetes 1.18 in CI/CD. #335
  • pytest & pytest-asyncio are pinned temporarily until fixed on their side. #352

Improvements:

  • Status as a sub-resource is detected and patched via separate API endpoints. #313
  • Security: Stop exposing the Authorization: and other HTTP headers in logs. #306
  • Documentation's little fixes. #97 #303

CI/CD automation:

  • Warnings now do fail the tests (warnings must be fixed — same as regular errors). #312
  • Python 3.8 in CI/CD. Python 3.7 is still tested. Python 3.9-dev for preview. #314
  • LGTM checks added to CI/CD, code improved. #302

Internal changes:

  • Rebalanced modules for lower complexity: classes & functions moved. #298
  • Deprecate prefixes and proxying methods of registries, make registries simpler. #315
