The RUN +option "ignore_error" is replaces by a "record_failed" option, and the +default is not to track any failing RUN executions. + +New keymaps, new modem, hid2hci updated. + +udev 145 +======== +Fix possible crash in udevd when worker processes are busy, rules are +changed at the same time, and workers get killed to reload the rules. + +udev 144 +======== +Bugfixes. + +Properties set with ENV{.FOO}="bar" are marked private by starting the +name with a '.'. They will not be stored in the database, and not be +exported with the event. + +Firmware files are looked up in: + /lib/firmware/updates/$(uname -r) + /lib/firmware/updates + /lib/firmware/$(uname -r) + /lib/firmware" +now. + +ATA devices switched the property from ID_BUS=scsi to ID_BUS=ata. +ata_id, instead of scsi_id, is the default tool now for ATA devices. + +udev 143 +======== +Bugfixes. + +The configure options have changed because another library needs to be +installed in a different location. Instead of exec_prefix and udev_prefix, +libdir, rootlibdir and libexecdir are used. The Details are explained in +the README file. + +Event processes now get re-used after they handled an event. This reduces +the number of forks and the pressure on the CPU significantly, because +cloned event processes no longer cause page faults in the main daemon. +After the events have settled, a few worker processes stay around for +future events, all others get cleaned up. + +To be able to use signalfd(), udev depends on kernel version 2.6.25 now. +Also inotify support is mandatory now to run udev. + +The format of the queue exported by the udev damon has changed. There is +no longer a /dev/.udev/queue/ directory. The current event queue can be +accessed with udevadm settle and libudedv. + +Libudev does not have the unstable API header anymore. From now on, +incompatible changes will be handled by bumping the library major version. + +To build udev from the git tree gtk-doc is needed now. The tarballs will +build without it and contain the pre-built documentation. An online copy +is available here: + http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/ + +The tools from the udev-extras repository have been merged into the main +udev repository. Some of the extras have larger external dependencies, and +they can be disabled with the configure switch --disable-extras. + +udev 142 +======== +Bugfixes. + +The program vol_id and the library libvolume_id are removed from the +repository. Libvolume_id is merged with libblkid from the util-linux-ng +package. Persistent disk links for label and uuid depend on the +util-linux-ng version (2.15) of blkid now. Older versions of blkid +can not be used with udev. + +Libudev allows to subscribe to udev events. To prevent unwanted messages +to be delivered, and waking up the subscribing process, a filter can be +installed, to drop messages inside a kernel socket filter. The filters +match on the : properties of the device. + This is part of the ongoing effort to replace HAL, and switch current +users over to directly use libudev. + Libudev is still marked as experimental, and its interface might +eventually change if needed, but no major changes of the currently exported +interface are expected anymore, and a first stable release should happen +soon. + +A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED +is not supported since while and udevd will log an error message at +startup. It should still be able to boot-up, but advanced rules and system +services which depend on the information not available in the old sysfs +format will fail to work correctly. + +DVB device naming is supplied by the kernel now. In case older kernels +need to be supported, the old shell script should be added to a compat +rules file. + +udev 141 +======== +Bugfixes. + +The processed udev events get send back to the netlink socket. Libudev +provides access to these events. This is work-in-progress, to replace +the DeviceKit daemon functionality directly with libudev. There are +upcoming kernel changes to allow non-root users to subcribe to these +events. + udev 140 ======== Bugfixes. +"udevadm settle" now optionally accepts a range of events to wait for, +instead of waiting for "all" events. + udev 139 ======== Bugfixes.
