Description
-----------
This BETA release of the Prime Calculator firmware and associated PC and Mobile software delivers fixes to outstanding issues. This document is not a complete list of all changes but highlights specific items. Only users willing to experiment with pre-release software and report issues to calcbeta@hp.com are invited to experiment with this release.


Please back up your calculator before the update. Any existing data on the device may be wiped during the update process. This beta is much less polished then any you had before.... you have been warned. "Here be dragons"

FIXED BUG: Doing something like ∫(2*X,X,0,X) in the plotter will now work properly.
NEW FEATURE: Units are accepted in TRUNC/ROUND.
NEW FEATURE: Handling fractional powers in plotting. This is to stop the "MY PLOT IS WRONG!!!!" type issues. This currently is bound to the "complex output" flag on page 1 of settings. Fractional powers can be of the size [1-9]/[1-9] and if matches the NTHROOT will be used internally.
Connkit program editor has similar options for adding files, different types, etc.
TEXTSIZE function, PRINT2D function (READLINE also for terminal input). TEXTOUT can now print 2D also

Mine wasn't. I had to choose Update Calculator form the CK Help menu.

Hi Tim,

This version number is incremented 1 from what is posted at HPCalc. Is there a newer version coming with other significant updates? Some of your notes seem to address a couple quirks I've found.
