This user-space software project now has support for intrusion detection sensors and humidity sensors. LM_Sensors 3.3.0 also provides support for many sub-features implemented by new hwmon drivers, some arbitrary limits have been removed from libsensors, there's new generic limit printing code in the sensors utility, and there's new chips known by the sensors-detect program. There's also been the variety of i2c/hwmon kernel driver updates in succeeding Linux kernel releases since the release of LM_Sensors 3.2 last October.
There's also many other bug-fixes and updates to be found in LM_Sensors 3.3.0.
The official release announcement came out by Jean Delvare on the mailing list.
