Enterprise

• NEW: Enterprise owners can now change their site's logo themselves, from the new Logo section of Enterprise Settings. Before, changing the logo meant asking Groups.io support. The section shows the current logo on the header's background color, and when you choose a new file it shows a preview on the same color before anything is uploaded, with a warning if the image isn't 400×100. Logos must be 400×100 PNGs with a transparent background; if an upload is rejected, the page says exactly why. The new logo appears in the site header straight away, and the image used for social media link previews is updated to match.
• NEW: Enterprise owners can upload an icon on the Enterprise settings page, next to the logo. It is the icon shown in browser tabs and on members' home screens when they add the site to their phone. It needs to be a square PNG at least 512×512, and the page previews it and warns about the wrong shape or size before uploading.
• CHANGE: The Enterprise setup checklist previewed an uploaded logo on a near-black background. It now previews it on the site header's color, so it shows how the logo will actually look.
• CHANGE: Enterprise sites showed the Groups.io icon in browser tabs and on home screens unless we had replaced it by hand. Sites without their own icon now get one with two initials from the site's name on a colored background, and it is redrawn when the site's name changes on the Enterprise settings page.
• BUGFIX: Changes saved on Enterprise Settings, such as the title, sign-up and +1 settings, login page text and single sign-on settings, were saved but could keep showing and acting on the old values until the site was restarted. They now take effect as soon as they're saved.

Enterprise

• BUGFIX: SAML setup could fail when an identity provider rejected the metadata fetcher's default client identification. Metadata requests now identify themselves as Groups.io.
• BUGFIX: SAML configuration errors incorrectly displayed a database error and discarded the submitted settings. The form now displays a specific SAML error and preserves the entered values for correction.
• BUGFIX: The Enterprise SAML request-signing setting advertised signed authentication requests without actually signing them, and SP metadata omitted the signing certificate. Enterprise owners can now prepare a dedicated certificate, import it into their identity provider, and explicitly enable request signing. SP metadata includes the prepared certificate and accurately reflects whether signing is enabled. Existing configurations remain unsigned until signing is explicitly enabled.
• NEW: Enterprise SAML settings now support certificate rotation: prepare and publish a replacement alongside the current certificate, activate it after coordinating trust with the identity provider, roll back if needed, and explicitly retire the previous certificate. Settings display certificate fingerprints, expiry dates, and warnings for certificates expiring within 90 days.
