Discussion

• Release candidates
  • Zach made release branch and started release candidates last Friday.
  • We installed on windows, worked, has correct version number 1.11rc2025....

• Windows installer signing
  • The Windows ChimeraX release candidate and daily builds are being signed with new certificate.
  • Testing today showed the release candidate installer still says "Don't run" and requires clicking More Info... then Run Anyway.
  • Under More Info it now says the publisher is UC San Francisco.
  • Greg believes we have an "EV" certificate meaning that we do not need to build reputation through downloads.
  • An online site said an EV certificate can take a few days before Windows SmartScreen recognized the thumbprint avoiding the "Don't run".
  • We will check later this week or next to see if the "Don't run" message goes away.
  • In the mean time Greg is putting a message on the Download page warning about the Don't run message and saying to press More Info....
