Improvements:

* Finalizer is not added if there are no deletion handlers. 118
* Deletion handlers can be optional to prevent adding finalizer. 118
* Script's dir is added to import paths to mimic Python's behaviour. 93 133
* `.status` is ignored in the last-handled state checks (except for fields used in field-handlers). 131
* `.metadata` is ignored in the last-handled state checks (except for labels & annotations). 131
* Operator freezes if the same-priority operator appears (previously, only warned). 114

Bugfixes:

* The peering self-record was not properly removed on exit. 114
* Restrict to `kubernetes<10.0.0` to keep Kopf runnable at all. 134

Internal changes:

* Examples can now have their own dedicated tests. 126

Improvements:

* Performance improvements when handling hundreds of resources. 109

Internal changes:

* Internal (non-public) packages restructured — to deal with the growing complexity. 124
* `kopf.engines` extracted from `kopf.reactor` (peering & posting & logging).
* `kopf.utilities` extracted from `kopf.reactor` (reacting to k8s changes).
* `kopf.clients` is the new `kopf.k8s` (renamed).
* `kopf.clients.auth` extracted from `kopf.config` (only auth-related routines).
* `kopf.config` got the configuration constants from all over the code.
* New configuration added:
* Configurable timeouts and thread pool sizes.
* Configurable level of k8s-events posted; others are skipped.
* Everything has been made asynchronous:
* All internal K8s API wrappers/adapters are made async.
* All blocking operations (incl. API requests) moved to thread pools.
* All k8s-event posting is done via a queue with a background posting task. 125
