HP Prime – Release Notes ------------------------- Date Released: 2018/07/06 Internal Versions ----------------- Firmware Version: 2.0.0.13865 (2018 07 06) Virtual Calculator Version: 2.0.0.13865 (2018 07 06) Connectivity Kit: 2.0.0.13865 (2018 07 06) Description ----------- This maintenance release of the Prime Calculator firmware and associated PC software delivers fixes to outstanding issues. This document is not a complete list of all changes, but highlights specific items. All users of the HP Prime calculator are encouraged to upgrade for the best possible experience. Please back up your calculator before the update. Any existing data on the device may be wiped during the update process. New Functionality and Changes (Calculator Software) 1. ROUND and TRUNC now interpret DMS inputs in a more expected manner (e.g. ROUND(45°29′57.7″,4) ----> 45°29′58″ ) 2.

This document is not a complete list of all changes, but highlights specific items. All users of the HP Prime calculator are encouraged to upgrade for the best possible experience. Backward Compatibility ---------------------- There is limited backward compatibility between this and earlier releases. Older Prime hardware (Revision A) does support this release, however the wireless, unit-to-unit, and data streamer functionality is not supported on earlier models. In the Help->About HP Prime screen the hardware revision will be displayed along with software version information. Mixing and matching software revisions is not encouraged and may cause unexpected results. Users are strongly encouraged to first backup their calculators with the older firmware and Connectivity Kit - then upgrade all their calculator software (firmware, Connectivity Kit, and Virtual Calculator). Upgrade the Connectivity kit first, before upgrading your calculator firmware. This order will produce the best experience. The geometry application and inference have received significant updates and earlier data files will not be compatible. Old data files from earlier revisions will not load and and a new empty data file will overwrite the old one. Due to some specific issues resolved, certain user programs may not run on the new system without changes first. Specifically, any commands with the Σ character in the name may need to be corrected to use the correct sigma character.

The specific fixes are listed in the table below. There were a number of stability, on-calculator help and memory usage improvements not listed in the table. Backward Compatibility This release of the Connectivity Kit is backward compatible with the HP Prime 1.0 firmware. However, some unexpected results may occur sending data from the Calculator to the Connectivity Kit when using prior versions. HP recommends that you upgrade your calculator to the matching 1.0.1 version of the firmware for best results.
