v0.49.0

[machine-controller-manager]

⚠️ Breaking Changes

• [OPERATOR] Removal of the following flags (and corresponding fields in associated structs): 'machine-creation-timeout' 'machine-drain-timeout', 'machine-pv-detach-timeout', 'machine-health-timeout=10m', 'machine-safety-apiserver-statuscheck-timeout', 'machine-safety-apiserver-statuscheck-period', 'machine-safety-orphan-vms-period', 'machine-max-evict-retries', 'node-conditions', 'bootstrap-token-auth-extra-groups', 'delete-migrated-machine-class'. The MCM no longer accepts these flags since these are options handled by the Machine Controller invoked by platform specific provider launchers. (gardener/machine-controller-manager#769, @elankath)
• [DEVELOPER] Deletion of 'Driver.GenerateMachineClassForMigration'. Providers need to adapt to this. (gardener/machine-controller-manager#769, @elankath)

✨ New Features

• [USER] Machine object won't turn from Pending to Running state if node.gardener.cloud/critical-components-not-ready taint is there on the corresponding node. (gardener/machine-controller-manager#778, @SimonKienzler)

🐛 Bug Fixes

• [USER] An edge case where all the machineSets were scaled down to zero has been dealt with. (gardener/machine-controller-manager#803, @himanshu-kun)
• [USER] Fix a bug in the bootstrap token creation that caused node to not be able to join the cluster due to an expired bootstrap token. (gardener/machine-controller-manager#773, @schrodit)

📖 Documentation

• [DEVELOPER] Added proposal for hot-update of resources (instance/Nic/Disk) (gardener/machine-controller-manager#761, @himanshu-kun)

• [OPERATOR] CVE categorization for MCM has been added. (gardener/machine-controller-manager#791, @dkistner)
• [DEVELOPER] The API generation now works again. Previously the API docs was generated to a location that was ignored by git and other API docs file was maintained. (gardener/machine-controller-manager#800, @ialidzhikov)
