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. Primary focus in this release is enhancements to statistics and graphing gestures.
Statistics 1 Variable:

- Plot view improvements
- Numerical view improvements
Statistics 2 Variable:
- Symbolic view improvements
- Plot view improvements
- Numerical view improvements
Inference:
- Symbolic view improvements
- Plot view improvements
Function:
- Plot view improvements: Ability to pinch/zoomin the X direction only or Y direction only. Ability to sketch afunction directly of the types exp, ln, sin, x^2, linear.
New Functionality:
- Added more distribution functions – density/cumulative/inverse: beta, exponential, gamma, geometric, negbinomial, uniform, weibull
- Added more random generation functions: binomial, chisquare, fisher, geometric, poisson, student
- Added functions DDAYS, DATEADD, DAYOFWEEK

- Added application variables AVars and DelAVars. Allows direct creation and access of application specific variables
- Applications now individually contained inside a directory structure to group variables and files together
- Sequence application can start at a location from 0-1000. Less stringent checking of recursion to allow things like U1(U2(N-1))
- Improved on-calculator DEBUG interface
- Added ability for title and display only in EDITLIST and EDITMAT
- Improved copy and paste in table editors through entire system
- Added CellName variable in spreadsheet to interact with names

- Added ability to use non-real inputs in the program catalog RUN menu
- Added clear confirmation on programs and note editor
Resolved issues and changes excluding CAS:
- Resolved issue with local variable initialization in a program with using a complex number
- Renamed “Program” and “Note”
- Resolved issue with having a space before the end in a cas end block
- Resolved issue with local lists to allow local l= {{{1,2}}}; l(1,1,2);
- Resolved issue with FOR STEP not rounding step calculation
- Resolved issue with sqrt from catalog not placing cursor nicely
- Improved setting/getting in stats using H1-H5, S1-S5
