v3.1.0 - the full move to Tachyon Mail

What's new

Login page branding

Administrators can now upload a custom logo from Admin → Branding. The logo
(PNG, JPG, GIF, SVG, or WebP) appears above the login form and is served
securely through PHP — it never sits in a web-accessible directory. Themes can
control size and position via CSS variables:

--login-logo-max-height
--login-logo-max-width

App directory renamed: snappymail/ → tachyon/

The application directory is now tachyon/v/3.1.0/ instead of
snappymail/v/3.1.0/. Upgrading from 3.0.x is the same process as any other
upgrade — extract the release over your existing installation. Once confirmed
working, you can delete the old snappymail/ directory.

Upgrading from SnappyMail? Same deal: extract over the top, data directory is
untouched, all config and mail data carries over.

Tachyon theme is now the default

Fresh installations use the Tachyon theme out of the box.

Debian package

A .deb package is now included in every release.
