v3.2.2

Bug fixes

• Reply/reply-all From field: Removed the upstream snappymail fallback that incorrectly set the To address of the original message as the From identity. The primary configured identity is now always used when no exact match is found.
• Nextcloud NC34 compatibility: Replaced removed OC\Server::getSession() and OC\Server::getUserSession() calls with the modern DI container API (ISession, IUserSession). Fixes loading failure on Nextcloud 34.
• Nextcloud session key: Fixed stale snappymail-passphrase session key in the Nextcloud plugin — now correctly reads tachyon-passphrase.
• PHP 8.5 compatibility: Removed deprecated curl_close() calls (no-op since PHP 8.0, deprecated in 8.5).
• Docker test config: Fixed container-structure-test paths (/var/lib/snappymail → /var/lib/tachyon) that were causing CI failures.

Tachyon v3.2.0

This is the first release with the Nextcloud integration built as part of the release. I have tested it a bit but would love more feedback from people using Nextcloud (and ownCloud). When I know it works stable, I plan to push it to the Nextcloud app store.

What's changed

Nextcloud / ownCloud integrations

• Both integrations are now built and included as release artifacts
• Fixed JS never loading (file was misnamed snappymail.js instead of tachyon.js)
• Fixed broken form submissions, routes, widget IDs, and template parameter mismatches
• Backward-compat alias for the legacy Nextcloud SnappyMail app

Docker

• Fixed builder stage failing due to Node.js version incompatibility (switched from yarn to npm ci)
• Fixed sed hotfix targeting wrong paths after SnappyMail → Tachyon rename

Branding

• SnappyMail renamed to Tachyon throughout all integrations, app strings, and localization
• Missing translation keys filled across all 37 languages

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.

Downloads

File	Description
tachyon-3.1.0.zip	Standard install
tachyon-3.1.0.tar.gz	Standard install (tar)

Upgrade

Extract over your current installation. No database changes, no config
migration needed.

Tachyon 3.0.1

First public release of Tachyon — a fork of SnappyMail 2.38.2, itself a fork of RainLoop.

Upgrading from SnappyMail? Drop this archive on top of your existing installation. Your data directory, config, and user-installed plugins are untouched.
