**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
* `kopf.timer` for regular and/or delayed activities & checks. 330
* `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
* A proper official documented way to configure operators; plus docs. 336 337
* Operators can be configured to use their own names for persistence, allowing multiple non-colliding operators for the same resources. 331

Improvements:

* Internals instant functions (lifecycles, when-filters) do not use thread pools anymore. 326
* Documentation is restructured for separate pages for all aspects of handling (kwargs, filters, etc). 325
* 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
* Configurable client-side timeouts for watch requests. 322 336
* Configurable storages for handling state & diff-bases. 331

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

Internal changes:

* Compatibility with Kubernetes 1.18 in CI/CD. 335

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

New features:

* Handler/resource filtering with arbitrary callbacks in `when=` option. 258 288

Bugfixes:

* Reaction cycle stops in the middle with no messages (improper "now" comparison). 285

Internal improvements:

* aiohttp 4.x readiness (restriction to stay on 3.x). 277
* Better GitHub issue/PR templates. 278

Improvements:

* Process the changes happened during the freeze mode once unfrozen. 256 257
* CRD's status field references fixed to match the examples. 262
* `cooldown` is renamed to `backoff` to match the usual terminology. 266

Bugfixes:

* "Line is too long" for objects longer than 128 KB in JSON (e.g. encrypted secrets). 276

Internal changes:

* CI/CD dependencies pinned to fight the unexpected changes. 265 274
* Minikube's RBAC-only mode is relaxed to "Node,RBAC". 270
