v1.5.0

AIS Operator v1.5.0

• Updated to go 1.23 and latest dependencies
• Added support for custom annotations passed from spec to aisnode containers via Annotations spec option
• Added support for custom environment variables passed from spec to aisnode containers via Env spec option
• Fixed a bug where rebalance would not properly disable and re-enable for upgrades if it had been modified manually
• Removed the option for the operator manager to run external to the k8s cluster
• Internal logic refactoring of AIS API and AuthN clients
• Added Sync option to version config
• Changed net.http.UseHttps option to solely control whether aisnode expects to use HTTPS rather than relying on presence of TLS secrets or cert manager issuer

v1.3.0

AIS Operator v1.3.0
