- Update to 3.2.0
* Added support for UDF file system (this change requires
util-linux 2.30). While adding support for UDF, the following
general improvements were made:
+ KPM now supports setting label for file systems where it can
only be done during initial formating (e.g. nilfs2 or udf)
+ File system label widget (QLineEdit) now validates its input
for certain file systems (at the moment only FAT and UDF),
not just maximum label length.
* Detection support for ISO9660 file system
* kpmcore now has lighter KDE Frameworks dependencies, KIO is no
longer necessary, KIconThemes dependency moved from kpmcore to
Partition Manager
* kpmcore now has its own fstab parser and writer. Before we
used to rely on glibc but it had no support for reading fstab
comments, etc.
