November and December in KDE PIM

Sunday, 7 January 2024 | KDE PIM Team

Here's our bi-monthly update from KDE's personal information management applications team. This report covers progress made in the months of November and December 2023.

Since the last report, 35 people contributed approximately 1500 code changes, focusing on bugfixes and improvements for the coming 24.02 release based on Qt6.

Transition to Qt6/KDE Frameworks 6

As we plan for KDE Gear 24.02 to be our first Qt6-based release, there's been on-going work on more Qt6 porting, removing deprecated functions, removing support for the qmake build system, and so on.

New feature

Kontact, KMail, KAddressBook and Sieve Editor will now warn you when you are running an unsuported version of KDE PIM and it is time to update it. The code for this is based on Kdenlive.


While the focus for Itinerary was also on completing the transition to Qt 6, with its nightly Android builds switching over a week ago, there also were a number of new features added, such as public transport arrival search, a new journey display in the timeline and a nearby amenity search. See Itinerary's bi-monthly status update for more details.

In KOrganizer it is no possible to search for events without specifying a time range (BKO#394967). A new configuration option was added to only notify about events that the user is organizer or attendee of. This is especially useful when users add a shared calendar from their colleagues, but don't want to be notified about events that they do not participate in. Korganizer intercepts SIGINT/SIGTERM signal. It will avoid to lose data during editing.


Work has begun on creating a tool that would help users to migrate their Akonadi database to a different database engine. Since we started improving SQLite support in Akonadi during the year, we received many requests from users about how they can easily switch from MySQL or PostgreSQL to SQLite without having to wipe their entire configuration and setup everything from scratch with SQLite. With the database migrator tool, it will be very easy for users to migrate between the supported database engines without having to re-configure and re-sync all their accounts afterwards.

Dan's work on this tool is funded by g10 Code GmbH.


The email composer received some small visual changes and adopted a more frameless look similar to other KDE applications. In addition, the composer will directly display whether the openPGP key of a recipient exists and is valid when encryption is enabled.

KMail composer new look

The rust based adblocker received further work and adblock lists can be added or removed.

We removed changing the charset of a message and now only support sending emails as UTF-8. This is nowaday supported by all the other email clients. But we still support reading emails in other encoding.

Now kmail intercepts SIGINT/SIGTERM signal. It avoids to close by error KMail during editing.

Laurent finished to implement the "allow to reopen closed viewer" feature. This provides a menu which allows to reopen message closed by error.

In addition a lot of bugs were fixed. This includes:

  • Fix bug 478352: Status bar has "white box" UI artifact (BKO#478352).
  • Load on demand specific widget in viewer. Reduce memory foot.
  • Fix mailfilter agent connection with kmail (fix apply filters)

A lot of work was done to rewrite the account wizard in QML. Accounts can now be created manually.


Bug 478636 was fixed. Postal addresses was ruined when we added address in contact. (BKO#478636). Now KAddressbook intercepts SIGINT/SIGTERM signal. It avoids to close by error it during editing contact.


Development focussed on fixing bugs for the release of GnuPG VS-Desktop® (which includes Kleopatra) in December.

  • OpenPGP keys with valid primary key and expired encryption or signing subkeys are now handled correctly (T6788).
  • Key groups containing expired keys are now handled correctly (T6742).
  • The currently selected certificate in the certificate list stays selected when opening the certificate details or certifying the certificate (T6360).
  • When creating an encrypted archive fails or is aborted, then Kleopatra makes sure that no partially created archive is left over (T6584).
  • Certificates on certain smart cards are now listed even if some of the certificates couldn't be loaded (T6830).
  • The root of a certificate chain with two certificates is no longer shown twice (T6807).
  • A crash when deleting a certificate that is part of a certificate chains with cycles was fixed (T6602).
  • Kleopatra now supports the special keyserver value "none" to disable keyserver lookups (T6761).
  • Kleopatra looks up a key for an email address via WKD (key directory provided by an email domain owner) even if keyserver lookups are disabled (T6868).
  • Signing and encryption of large files is now much faster (especially on Windows where it was much slower than on Linux) (T6351).


2 bugs were fixed in sieveeditor:

  • Fix BUG: 477755: Fix script name (BKO#477755).
  • Fix bug 476456: No scrollbar in simple editing mode (BKO#476456).

Now sieveeditor intercepts SIGINT/SIGTERM signal. It avoids to close by error it during editing sieve script.


Now it intercepts SIGINT/SIGTERM signal. It avoids to close application during import/export.
