RustBox/CHANGELOG.md

RustBox changelog

What changed in each RustBox release, written for the people who use and run it. Technical details are in the documentation.

0.2.29

• An open message thread now updates automatically when a new message for that thread arrives via realtime events; reopening the thread is no longer required.

0.2.28

• Replying to a message you sent no longer addresses the reply back to yourself; RustBox chooses the other thread participant(s), including when aliases/identities are used.
• The mailbox toolbar now switches the message list between threaded and flat views. The compact icon-only control matches the message-selection button and changes its icon to reflect the active view. Threaded mode groups related messages by Message-ID/In-Reply-To/References, shows the thread size, and lets each thread expand or collapse; the reader follows the same persisted mailbox preference.
• Polish text decoding is more tolerant of legacy mail: RFC 2047 ISO-8859-2 subjects and common UTF-8/Windows-1252 or ISO-8859-2/Western-Latin mojibake are repaired in headers, bodies and cached message previews.

0.2.27

• Monochrome mode now creates a custom copy when editing a predefined interface style, just like direct colour changes.
• Wide message rows give more room to the subject and show the complete subject in a tooltip.
• Read/unread, flag and open actions no longer reserve hidden horizontal space; they appear to the left on hover.
• Shift-click message popups now open as a reader-only embedded view instead of briefly showing the full mailbox.
• Opening a message in a new window or tab now uses the same reader-only embedded view as the popup instead of the full mailbox/fullscreen layout.
• Adaptive HTML mail colours now derive light/dark mode from the actual reader background, so custom palettes stay readable even when their saved theme mode does not match their visual brightness.
• Mailbox storage is now clickable: folder properties can show IMAP-reported size in MB, and a storage dialog visualizes per-folder usage with progress bars.

0.2.26

• RustBox now has a license: the GNU AGPL v3, plus an optional paid commercial license for companies that prefer different terms. The About page explains both.
• The About page was redesigned: author, repository, license and a short note on the project's origin.
• RustBox is now developed independently of Oxi, the project its first version was forked from. The tools for synchronising with Oxi were removed.
• New documentation: a complete feature list with screenshots, a rewritten README and this user-friendly changelog.
• Settings notes in Polish now appear in Polish right after the page loads.
• Code cleanup with no change in behaviour.

0.2.25

• Filters – Apply now: a rule can be run on mail already in a folder, not only on new mail. "Check matches" shows how many messages a rule would affect; each rule in the list has its own "Apply now". Messages that cannot be checked with certainty are left untouched.
• Filters – more options:
  • exceptions ("except if…");
  • new conditions: To only, Cc only, message size, has attachment, high priority;
  • new actions: add a label, move to Trash.
• Filters – easier to create:
  • ready-made templates;
  • an offer to create a missing target folder;
  • "Always move messages from this sender…" in the message menu;
  • the quick filter can also be applied to messages already in the folder.
• Filter descriptions and confirmation buttons are translated.
• The message right-click menu is much shorter thanks to submenus and always fits the window, so Delete is always reachable.
• Fixed editing a predefined style mixing two styles together. Its layout can now be adjusted while it keeps its look, and only a colour change creates a custom copy (after asking).
• Fixed the "Soft" contrast option removing all borders.
• Fixed subfolders appearing in the wrong place in the folder list; they now appear directly under their parent folder.

0.2.24

• The Style gradients switch now works at every style depth, and every predefined style has optional gradients.
• New retro styles: Windows XP, Mac OS X Aqua, iOS 6, Windows 7, Frutiger Aero and BeOS.
• New time-of-day theme: light during the day, dark in the evening, at times you choose.
• Optional account colour, shown as a stripe at the top and a dot next to the address.
• A warning when your custom colours make text hard to read.
• Placeholder rows while a folder loads, and a smooth transition when the theme or style changes.
• Calendar: a second reminder per event (for example one day before) and default reminders for new events. All-day events are reminded at the start of the working day.
• The style list is grouped into categories and uses short names in English and Polish.
• Fixes:
  • a dark selection colour in the light theme;
  • subjects squeezed by previews in the message list;
  • the flagged-message marker;
  • the reader toolbar on narrow screens;
  • clearing an event reminder.

0.2.23

• Style depth: choose whether a predefined style changes only colours, also the layout, or the whole look ("immersive": shapes, fonts, panes, app bar and backdrop).
• A separate Style gradients switch.
• All styles were brought to a common standard with light and dark versions.
• 14 new styles: Dracula, Catppuccin, Solarized, Gruvbox, Tokyo Night, Rosé Pine, Everforest, Synthwave, Paper, Terminal, Aqua Glass, Linear, Material You and Retro 95.
• Database upgrade history was consolidated. Very old installations must first be upgraded with version 0.2.22.
• Fixed creating a new MySQL database.

0.2.22

• Snooze: hide a message until a chosen time and see all snoozed messages in one list.
• Undo Send: a few seconds to cancel a message after pressing Send (the length can be set by the administrator).

0.2.21

• Stronger protection against password guessing: repeated failures lock the mailbox or address for a growing time, before the mail server is even contacted.
• Login works reliably on installations without HTTPS, while secure cookies are still used whenever HTTPS is available.
• Memory protection when sending large attachments: oversized messages are rejected early and only a limited number are prepared at the same time.
• Ctrl/Cmd-click opens a message in a new tab, Shift-click in a small window.

0.2.20

• Messages without a date now get the date when they were received instead of landing at the end of the list.
• "Forward as attachment" attaches the original message exactly as received.
• Fixed recovery after an interrupted first synchronisation.

0.2.19

• HTML messages use all the available height in the reader and adapt when the window or layout changes.

0.2.18

• Better choice of the sender identity and signature for new messages.
• Undo and redo shortcuts in the editor.
• Better display of older and marketing HTML e-mails in light and dark themes.
• Moving a message no longer triggers a "new mail" notification.
• Quick account switcher in the top bar when several accounts are signed in, and combined notifications from selected accounts. The administrator can turn multi-account off.
• Signature editor improvements: equal-height fields, a source view and image insertion.
• Shift-click selects a range of messages, and the list has first/last page buttons.
• Images embedded in signatures are no longer shown as attachments.

0.2.16

• Optional adaptive colours for HTML e-mails, so they fit the dark or light theme.
• Paged message list (300 per page by default), with optional smooth loading or loading the whole folder.

0.2.15

• Fixed sticky bold/italic formatting in the signature editor.
• New messages with a signature get an empty line to type in above it, and a subtler separator.

0.2.14

• Compact single-line message rows when the list is wide (can be turned off).
• Per identity, choose whether the signature is visible while writing or added only when sending.
• Resizing panes no longer shows errors.

0.2.13

• Deleted attachments are always removed from storage, even after a temporary storage failure; cleanup is retried automatically.

0.2.12

• Drafts:
  • drafts from the Drafts folder, including ones created in other mail clients, open directly for editing;
  • new "Save draft" and "Delete draft" buttons;
  • saving a draft no longer causes a "new mail" notification.
• Composer:
  • images can be pasted, dragged into place, resized with handles, aligned and cropped;
  • added images are embedded in the text by default;
  • attachments can be embedded or inserted as links;
  • the address fields can be hidden to give the editor more room.
• Long recipient lists are collapsed in the reader.
• A "Load all" button next to "Load more" in the message list.

0.2.11

• Import of contacts and identities from Roundcube.
• All predefined styles can be edited.

• Browser shortcuts such as copy, paste, find and reload are no longer captured by RustBox.
• 300 messages per page by default.

0.2.8

• Folder counters are always accurate, and marking messages as read updates them instantly without reloading the list.
• An activity indicator shows synchronisation and indexing progress.
• An administrator diagnostics endpoint, disabled by default and protected by an address list and password or token.
• Stronger optional security headers, and less information published before login.
• Quieter logs by default.

0.2.7
