 This release fixes an issue when Docker Hub rate limit is not properly handled
 by Flux daemon as rate limiting. Docker Hub sends its rate limit warnings as an
 error that does not include the expected "429" Too Many Requests status code.
 
+This release also includes a base image upgrade to Alpine 3.14.2 that mitigates
+several CVE scan warnings in the base image related to openssl and libgcrypt.
+
 ### Fixes
 
 - Adding Docker Hub rate limit condition message [fluxcd/flux#3543][]
 
 ### Maintenance and documentation
 
 - Add CodeQL Security Scanning [fluxcd/flux#3446][]
+- Upgrade alpine:3.14.1 to alpine:3.14.2 [fluxcd/flux#3545][]
 
 ### Thanks
