Overview

This release is primarily focused on adding support for newer Kubernetes versions (v1.19+), but does introduce breaking changes for prior Kubernetes versions.

ImageSwap v1.4.2 should be used for Kubernetes versions below v1.19.0

ImageSwap v1.5.0 is using a newer release of the Kubernetes Python Client library which removed some previously deprecated API's and changed the way the CertificateSigningRequest resource is handled for the webhook Cert Bundle.

This release also moves to using a new syntax (::) to separate the key and value portions of a map definition in the maps file. Backwards compatibility is maintained for the existing : syntax, but this has been deprecated and should not be used. Please update any existing map configurations to use the new syntax.

This release also adds additional validation to catch errors associated with specifying a registry in a map definition key that includes the :<port_number> syntax. Previously this would result in an error and a stack trace. This is now handled gracefully and the new map separator syntax should allow for registries to include ports going forward.
