Elle est datée du 31 mars, et comme la fois précédente, elle concerne à la fois le firmware de la Prime (numéro de version interne 0.031.6030), le connectivity kit et la version ordinateur.
Le changelog est imposant, et on ne va pas tout traduire ligne par ligne
On voit des bugfixes, des nouvelles features - et aussi une mention de différences de révision matérielle entraînant des features réduites sur les vieilles machines. Reste à savoir quelles sont ces machines de révision matérielle A.
Bien sûr, nous (en particulier critor) donnerons plus de détails au plus vite, selon le résultat des tests
HP Prime – Release Notes
-------------------------
Date Released: 2014/03/31
Internal Versions
-----------------
Firmware Version: 2014 03 31 (6030)
Virtual Calculator Version: 2014 03 31 (6031)
Connectivity Kit: 2014 03 31 (6026)
Description
-----------
This release of the Prime Calculator firmware and associated PC software delivers significant new features and fixes 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.
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. Function variables will now also error if the function parameter is using a reserved system function name (example: SIN or COLOR). Additionally, the TRIANGLE commands were modified to allow TRIANGLE, LINE and FILLPOLY to share similar data and syntax to enable easier creation of complex 3D drawings
New Functionality (Connectivity Kit)
------------------------------------
1. Application has had major improvements to the user interface. Please refer to the included connectivity kit User's Guide for instructions and details.
2. Support for the HP Wireless Classroom network has been introduced. Please see http://www.hp.com/calculators/ for details on the Wireless Classroom kit.
3. Greatly enhanced communication speed over USB link to calculator.
New Functionality (Calculator Software)
---------------------------------------
1. Improved touch support throughout system. This includes pinch to zoom support in graphing applications, and kinetic scrolling.
2. Pressing HELP in an open command line will attempt to find the name of a command based on the prior input up to the cursor position to display system help for that command.
3. Includes Edition 2 of the on calculator help files (English only in this release).
4. Greatly enhanced robustness and capability of the Statistics 2Var logistic fit.
5. Wireless support for capable units turned on. Wireless icon will appear in the right top corner menu for units that can support the HP Prime Wireless Kit.
6. Calculator unit-to-unit communications has now been enabled on units that can support it.
7. Numerical values now can be displayed with digit groupings. Examples include: 1,234.567 1 234.567 and 1’234,567
8. Two new numerical display formats have been introduced. These are “floating” which only displays up to a specified number of digits, and “rounded” which is similar to the “fixed” format except trailing zeros are suppressed.
9. Decimal fractions now appear with a zero, as in 0.25.
10. Vectors are now displayed as a single line object until they become a matrix. This aids in distinguishing vectors and matrices.
11. User selectable first day of week setting for use through the system.
12. First boot unlock and settings wizard. User will be asked to confirm language selection and some initial settings.
13. Inference application now can do Chi-Square calculations and Linear Regression T calculations.
14. Geometry application has been completely redone and is much faster, consistent, and capable than before.
15. Enhanced color pickers allow a greater range of color selection.
16. Pressing ENTER will now open chooser in a dialog or toggle checkbox.
17. Enhanced unit object display to ensure a more standard form with complex units.
18. TRIANGLE, FILLPOLY and LINE commands can now draw multiple objects in a consistent way with each other. Useful for very complicated 3D drawing in user programs.
19. INPUT command can now create multi-page dialogs and contain choose boxes, check boxes and grouped check boxes. It can also allow specific item types and gives control of parsing behavior for input. It also supports size and position control.
New Functionality (Virtual Calculator)
--------------------------------------
1. A horizontal skin has been included for use with monitors that are restricted in the vertical pixel range.
