Many users +depend on the current sysfs layout and the information not available in the +deprecated layout. All remaining support for the deprecated sysfs layout is +removed now. + +udev 149 +======== +Fix for a possible endless loop in the new input_id program. + +udev 148 +======== +Bugfixes. + +The option "ignore_device" does no longer exist. There is no way to +ignore an event, as libudev events can not be suppressed by rules. +It only prevented RUN keys from being executed, which results in an +inconsistent behavior in current setups. + +BUS=, SYSFS{}=, ID= are long deprecated and should be SUBSYSTEM(S)=, +ATTR(S){}=, KERNEL(S)=. It will cause a warning once for every rule +file from now on. + +The support for the deprecated IDE devices has been removed from the +default set of rules. Distros who still care about non-libata drivers +need to add the rules to the compat rules file. + +The ID_CLASS property on input devices has been replaced by the more accurate +set of flags ID_INPUT_{KEYBOARD,KEY,MOUSE,TOUCHPAD,TABLET,JOYSTICK}. These are +determined by the new "input_id" prober now. Some devices, such as touchpads, +can have several classes. So if you previously had custom udev rules which e. g. +checked for ENV{ID_CLASS}=="kbd", you need to replace this with +ENV{ID_INPUT_KEYBOARD}=="?*". + +udev 147 +======== +Bugfixes. + +To support DEVPATH strings larger than the maximum file name length, the +private udev database format has changed. If some software still reads the +private files in /dev/.udev/, which it shouldn't, now it's time to fix it. +Please do not port anything to the new format again, everything in /dev/.udev +is and always was private to udev, and may and will change any time without +prior notice. + +Multiple devices claiming the same names in /dev are limited to symlinks +only now. Mixing identical symlink names and node names is not supported. +This reduces the amount of data in the database significantly. + +NAME="%k" causes a warning now. It's is and always was completely superfluous. +It will break kernel supplied DEVNAMEs and therefore it needs to be removed +from all rules. + +Most NAME= instructions got removed. Kernel 2.6.31 supplies the needed names +if they are not the default. To support older kernels, the NAME= rules need to +be added to the compat rules file. + +Symlinks to udevadm with the old command names are no longer resolved to +the udevadm commands. + +The udev-acl tool got adopted to changes in ConsoleKit. Version 0.4.1 is +required now. + +The option "last_rule" does no longer exist. Its use breaks too many +things which expect to be run from independent later rules, and is an idication +that something needs to be fixed properly instead. + +The gudev API is no longer marked as experimental, +G_UDEV_API_IS_SUBJECT_TO_CHANGE is no longer needed. The gudev introspection +is enabled by default now. Various projects already depend on introspection +information to bind dynamic languages to the gudev interfaces. + +udev 146 +======== +Bugfixes. + +The udevadm trigger "--retry-failed" option, which is replaced since quite +a while by "--type=failed" is removed. + +The failed tracking was not working at all for a few releases. The RUN +option "ignore_error" is replaced by a "fail_event_on_error" 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 '.'.
