v0.3.0

Release description

The major new feature for this release is the introduction of update strategies:

• The strategy latest will evaluate the creation date and chose the latest created tag matching the version constraint for update
• The strategy name will pick the last found tag according to alphabet sorting
• The strategy semver (the default) will pick the latest allowed version according to version constraint

Also, this release introduces a simple in-memory cache for tag meta data and the code has seen some refactoring. Please see below for breaking changes and a complete list of things that have been done.

Upgrade notes (no really, you MUST read this)

• Syntax change for running: argocd-image-updater run [flags] instead of argocd-image-updater [flags] has now to be used
• Attention: Helm annotation names have changed from <image_alias>.image-{name,tag,spec} to <image_alias>.helm.image-{name,tag,spec}
• Specifying target image name for Kustomize applications now require their own annotation, the image alias is not re-used for this anymore
