• Datumsökning i formatet DD-MM-ÅÅÅÅ med kalenderväljare
• Kommer ihåg storlek och position för alla sekundära fönster

• Åtgärdat: e-post visas åter så som avsändaren har utformat den. Om den inbyggda webbläsaren startade långsamt blev läsaren kvar i ren text tills appen stängdes; nu försöker den själv igen och visar det ursprungliga e-postmeddelandet
• Vid nya installationer vänder appens mörka tema inte längre på e-postens färger: avsändarens färger behålls (alternativet "Tvinga mörkt tema" finns kvar i Inställningar)

• Läsningen omgjord: e-post visas som avsändaren utformade den, med justerade tabeller, hela läsfönstrets bredd och mer kompakt text
• Åtgärdat: mörka e-postmeddelanden med osynlig text samt arabiska eller hebreiska meddelanden som var felaktigt justerade
• Citat i e-post med ren text visas som indragna block, som i andra e-postprogram

• Fixed: a sent message could sit in «Sending…» for up to 5 minutes before going out. It now leaves right after the 8-second «Undo send» window

• New: translate a message inside the reader. Choose «Translate» (or right-click) and the message appears translated, with a button to go back to the original. It works on the selected text or on the whole message, and the text only leaves your computer after you agree
• New: PDF attachments open in a window of the app itself
• Safer: the PIN lock now also blocks keyboard shortcuts and the tray actions
• Safer: remote-content blocking is stronger, opened attachments are marked as coming from the Internet, and updates only install once their integrity checksum (SHA-256) is confirmed
• Faster: opening a folder no longer waits for a full sync to finish, and «Clear cache» and the automatic backups no longer freeze the window
• Fixed: recurring calendar events shifted by an hour after the clocks changed, and daily ones older than 8 years disappeared; importing an .ics with «repeats 4 times» or «Monday, Wednesday and Friday» now works
• Fixed: «Empty Trash» could delete an old email on the very day you moved it to Trash
• Fixed: importing contacts from Outlook no longer mangles accents, and the import is faster and all-or-nothing
• Fixed: a contact with a comma in the name («Smith, John») no longer breaks sending, and text typed while replying is no longer lost while the original message loads
• Fixed: the installer creates the shortcut when asked, cancelling halfway no longer leaves a half-installed app, and uninstalling while the app is open warns you
• Removed: the manual Google and Microsoft setup (the app already comes configured)

• Fixed: updating from inside the app could fail with "the process cannot access the file" and leave the install folder empty. The installer now completes the update either way, and the app now launches it from a neutral folder

• Faster: opening a message with the arrow keys is instant, and stepping from one to the next no longer flashes blank
• Faster: new messages are downloaded in the background, so they are already there when you open them
• Faster: the message list no longer freezes the window during a sync, and large folders load faster
• Fixed: "Loading…" could stay up forever on a message
• Fixed: messages with a large embedded image lost their formatting and showed as plain text
• More stable: fewer simultaneous contact-photo lookups (and none while you are offline) and one error dialog per 30 seconds instead of one per repeated failure

• Fixed: forwarding a message already forwarded by Gmail or Thunderbird ("Fwd:") doubled the prefix into "Fw: Fwd: ..."
• Fixed: replying to all on a message sent to two of your own configured accounts put the other account back in Cc
• Fixed: a successfully sent message could end up with no record at all (not in Sent, not as a draft) if the account's Sent folder had not been detected yet
• Fixed: choosing an app language different from Windows' own language did not switch dates and attachment sizes to that language
• Fixed: "Block remote content" missed images/CSS with a schemeless address (e.g. "//example.com/image.gif")
• Improved: opening a message with a direct click is now instant (no more of the short pause meant for keyboard navigation), and coming back from the system tray now warms up the renderer before your first click
• Version metadata added to the installer, and the release process now always requires the installer's checksum before a version can be published

• Fixed: restoring the app from the system tray could leave the open message blank, and clicking it again did nothing; only opening a different message and coming back brought the content back

• Fixed: opening a message could briefly show the previous message's body before the new one appeared
• Fixed: archiving, deleting or moving several selected messages clicked out of order could leave the next selection far from the right spot in the list
• Fixed: archiving then marking the same message as spam in very quick succession could race each other
• Improved: several interface animations (buttons, menus, notices, the "Loading…" overlay) now use the same smoothness throughout the app instead of switching state abruptly
• Improved: opening a message or switching themes no longer briefly blocks the window while the app is busy syncing

• New: on fresh installs, HTML emails now show in the dark theme by default instead of always on a white background. If you already use Sidsmail, this stays off so nothing changes without warning; turn it on in Settings, Reading, "Force dark theme on all messages"

• Fixed: when a message row was selected, the account color bar and the selection marker were both squeezed into the same corner; the account bar reappears as soon as you move to another message
• Fixed: "disabled" text (for example, options that do not apply right now) looked almost identical to normal secondary text; now the difference is clearer

• New installer and uninstaller, redesigned from scratch (Portuguese and English for now, more languages coming)
• Fixed and polished: context menus (Move to, Message color, Snooze…) had submenus opening light, square corners, and hover highlighting that went the wrong way; now consistently dark, with a soft shadow and quieter separators
• Fixed: the context menu inside an email (Save as, Print…) also always opened light, regardless of theme
• More recognizable community icon in the installer

• Fixed: the app could get stuck and be closed by Windows when opening an email whose preview failed to load, now it falls back to plain text on its own instead of waiting forever
• New: "Import from Thunderbird" also in Settings › Accounts, any time, not only in the first-account wizard
• Installer: the "Select destination location" page is gone, there was no real choice left to make there
• Installer: the help and support links on the final page are now clickable
• Installer wizard now in the same 23 languages as the app, picking your Windows language automatically
• Various wording touch-ups across the app, the site and the installer

• Fixed: the app could get stuck running invisibly in the background, unresponsive, after installing an update from inside it
• New: "Import from Thunderbird" in the first-account wizard, bringing over the server, port and email of accounts already set up in Thunderbird (never the password, which you still type in yourself)
• Redesigned installer with a softer, more on-brand look
• Installer: when updating, closes only Sidsmail, never other open applications

• Fixed: an account you just added could disappear after restarting the app, because settings weren't saved while the window was maximised, the normal case on a fresh install
• Fixed: the "Unread" folder could close the email you were reading again, this time while searching inside it
• Fixed: a calendar reminder could keep firing for an occurrence you had already excluded from a series
• Fixed: "Repeat until" no longer accepts a date before the event's start
• Fixed: the spell checker while typing now follows the app's language (it was fixed to Portuguese)
• The app now checks for updates every 6 hours while open, in addition to on launch
• Installer: now checks for the .NET 10 runtime (was checking for the outdated .NET 8)

• Fixed: the message history for a contact could miss messages received with different capitalisation in the sender's address
• Fixed: importing a vCard contact with a multi-line note could corrupt the text
• Fixed: Ctrl+Z after "mark all as read" could re-mark the wrong messages as unread in some cases
• Fixed: "Block remote content" didn't always fully clear a blocked image's address
• Fixed: compressing a photo taken in portrait could come out sideways or upside down
• Several internal stability fixes to syncing and automatic sign-in
• Visual touch-ups to the Calendar and Account settings

• Fixed: the icon row at the bottom of the sidebar (Calendar included) no longer gets clipped, the default width now fits all seven icons

• New: local Calendar, with events, recurrence, contact birthdays, reminders, and automatic .ics invite detection in emails
• Fixed: the "Unread" folder no longer closes or hides the email you're reading the moment it's marked read
• Fixed: account settings no longer get lost if the settings file was briefly locked while saving
• Reduced antivirus false positives in the installer

• "Add account" → Microsoft OAuth (Outlook, Hotmail, Office 365) now available with one click
• Modern authentication support for Microsoft accounts without requiring app passwords

• "Add account" → Google now works for anyone with one click, no app password, no console
• Microsoft is still coming

• "See what's new" now opens the version history inside the app, not the browser
• Downloads and visits in Settings › About redesigned: a small tidy badge, matching the site

• The desktop icon is now always created on install (it used to depend on a hidden option in the wizard)
• The app now opens maximised the first time it's launched

• "See what's new" button in Settings › About, to check the version history any time
• Custom installer artwork (icon with a glow, no more generic 3-D box)
• The update and support URLs are no longer user-configurable, they were leftover clutter

• Download counter in Settings › About
• Contact and another project by the author (sidstuga.app) in About and on the site
• Install fixes (file-in-use when updating, installer build)
