Kexi/Releases/3.1.0 Changes

From KDE Community Wiki

General highlight: focus of the 3.1 release has been put on overall stability and preparing the KEXI frameworks, KDb, KProperty, KReport, for general use in other (non-KEXI) software projects. API of these frameworks since the final 3.1.0 release is guaranteed to be stable until the 4.0.0 release.

Since the 3.0.2 release KEXI and the frameworks received over 220 improvements and bug fixes.

Documentation of the frameworks has also improved and is available at https://api.kde.org/kexiframeworks, although tutorials and reference have to be added in coming releases. KEXI user's manual is outdated as it covers older versions 2.x. We're sorry for the inconvenience.

Together with stabilization of the KEXI frameworks, improvement of translations for messages is also expected.

Note

KEXI 3.1.0 depends on the KEXI frameworks in version 3.1 or newer so it won't work with 3.0. Since 3.1.0 stable we plan to maintain backward binary compatibility with version 3.1.0 for all the frameworks. Just like the KDE Frameworks, we recommend to upgrade all the KEXI frameworks to the same version.


Changes in KEXI

Highlight: Integration of KEXI with non-KDE Plasma desktops has been further improved. On such desktops (e.g. XFCE, MS Windows) KEXI now displays simplified file requester. It is also possible to use this feature on Plasma desktops. Moreover, settings of a single-click mode are better detected on non-KDE Plasma desktops.


KEXI app 3.1 uses all the three KEXI frameworks and the version 3.1 is a minimal version required by to run the app.

Changes in KDb

KDb is a database connectivity and creation framework for various database vendors.

Highlight: Query schema cache is now created in the context of database connections, so there is one cache per connection, not one global. That said, table and query schema objects themselves are now independent of connection objects.

There are multiple renames in the API of KDb to make it easier to use. Private APIs have been moved out of the public header files. More enums have been added to replace harder to read boolean arguments.

Generation of native SQL statements that is performed in the background by KDb has been improved to cover more use cases, e.g. COLLATION and ORDER BY keywords are now more carefully used as do table aliases and lookup fields features. SQL parser of user-defined statements written in a KDbSQL dialect now reports more errors when needed and accepts more statements that were previously not recognized as valid.

New debug functions added in 3.1 can be helpful while developing with KDb.

Changes in KProperty

KProperty is a property editing framework with editor widget similar to what is known from Qt Designer.

Highlight: Property groups are now supported (they were missing in past versions) and their visibility now can be changed. Group for given property can be now found.


"unit" property option has been replaced by two more general options "suffix" and "prefix" that are supported for double, integer and composed types.

Property editor view can be set to display property descriptions as tooltips.


APIs of KProperty received multiple renames to make it easier to use. Private APIs have been moved out of the public header files. More enums have been added to replace harder to read boolean arguments.

There are fixes related to displaying minimal, URL or null values, checking ranges and updating values of sub-properties.
