v1.16.0

Additions

• For Ansible-based operators, add default resource limits for the manager. (#5274)
• Add annotation to specify the default container. More info here. (#5330)
• Add PHONY targets to Makefile. (#5330)
• Add # TODO(user): Configure the resources accordingly based on the project requirements. into the file config/manager/manager.yaml to make this requirement clear for users. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/. (#5330)
• For Golang-based projects, added ignore-not-found flag to the uninstall and undeploy Makefile targets. This change allows make undeploy and make install to continue if Kustomize encounters a missing resource. You can invoke this feature by calling make undeploy ignore-not-found=true. (#5330)
• Add new optional validator Good Practices. You are able to test your bundle against good practices defined under operator framework solutions by running:

$ operator-sdk bundle validate ./bundle --select-optional name=good-practices OR $ operator-sdk bundle validate ./bundle --select-optional suite=operatorframework 

(#5448)

• Add the deprecated APIs optional checker, alpha-deprecated-apis, to the operatorframework suite. (#5407)

Changes

• Upgrade OPM version that is used by default to 1.19.1 in the generated Makefile so make catalog-build also works on OSX. (#5099)
• For Ansible-based operators, bumped the operator_sdk.util ansible module to 0.3.1. (#5462)
• For a more consistent user experience, ensure that all areas that require to be changed are marked by TODO(user). (#5330)
• For Helm-based Operators, adopted the same default resource limit values used to scaffold Golang-based projects. (#5330)
• For Golang-based Operators, increase the values used in the default scaffold to define the resource limits usage and make clear the need to optimize its values based on the Operator requirements. (#5330)

Deprecations

• Deprecation of the Optional(stage: alpha) Community Operator bundle validation. Its checks were moved to the external validator. (#5414)

Bug Fixes

• Optional OperatorHub.io validator called by operator-sdk bundle validate ./bundle --select-optional name=operatorhub now includes a previously missing category Modernization & Migration. (#5375)
• Improves the validate bundle spec error message to provide a better explanation when invalid service accounts are found. (#5375)
• Improve scaffolding to filter existing multiline code fragments. More info kubernetes-sigs/kubebuilder#2343. (#5330)
