• plugins/logs: Previously while passing the decision log plugins's status to the Status API, the plugin held the mutex while a status upload was in process. This had the potential to block new decisions from being written to the plugin's buffer. To avoid this situation, a local copy of plugin's status is created (#5966) authored by @ashutosh-narkar
• download: Public docker repositories require an authorization handshake where the client needs to respond to challenges marked by the WWW-Authenticate header of a 401 Unauthorized response. Errors were returned when downloading a public image as it was assumed that authorization is not necessary for public repositories. This fix addresses this issue by challenging any 401 Unauthorized responses by passing it to the docker.Authorizer (#5902) authored by @DerGut
