@umehrot2 - The redirects in the config file are throwing errors when I try to build it locally, I guess you need to merge this PR first then build this PR again:

Error: You are trying to create client-side redirections to paths that do not exist:
- /releases/release-0.9.0
- /releases/release-0.9.0
- /releases/release-0.9.0
