Upgrade notes:

• NetBox has been updated to version 4.x. This chart should still work with 3.7.x as well by overriding the image, but it is not officially supported.
• Potentially breaking changes:
  • The extraContainers setting has been renamed sidecars to match conventions.
  • The extraInitContainers setting has been renamed initContainers to match conventions.
  • The metricsEnabled setting has been renamed metrics.enabled to match conventions.
  • The serviceMonitor setting has been moved to metrics.serviceMonitor to match conventions.
  • The jobResultRetention setting has been renamed jobRetention to match the change in more recent versions of NetBox.
  • The remoteAuth.backend setting has been renamed remoteAuth.backends and is now an array.
  • The remoteAuth.autoCreateUser setting now defaults to false.
  • NAPALM support has been moved into a plugin since NetBox 3.5, so all NAPALM configuration has been removed from this chart.
  • Please consult the NetBox and netbox-docker release notes in case there are any other changes that may affect your configuration.
• The Bitnami PostgreSQL sub-chart was upgraded from 10.x to 15.x; please read the upstream upgrade notes if you are using the bundled PostgreSQL.
• The Bitnami Redis sub-chart was upgraded from 15.x to 20.x; please read the upstream upgrade notes if you are using the bundled Redis.

@LeoColomb Ah thanks! Been meaning to start organizing this now that I've come out from under the flurry of initial development on the NBE chart.
