So why a version number increase again? First of all, the structure of the XPRESS package has changed once more a bit, and with it the way your measurement scripts should look like. The "hub" package is gone, and the whole XPRESS functionality is now made available by a simple
use Lab::Measurement;statement at the start of your file. The example scripts (also on the website) have been adapted accordingly.
In addition, we have implemented a generic support for so-called multichannel instruments, as for example multimeters with several input channels. This is a more generic solution compared to earlier multichannel sources, and also ties in with the device cache mechanisms. So far, the drivers for the Oxford Instruments ITC temperature control system and the Agilent 34420A nanovoltmeter are multichannel-aware.
Next, now at the start of any measurement the entire device configuration as far as accessible by the driver is saved into a file for your later perusal. Should you ever try to decipher mystery data months later...
Finally, a driver for the Andeen-Hagerling AH 2700A capacitance measurement bridge has been added, and of course also quite some bugfixes. Enjoy!
