New Functionality (Connectivity Kit)
-----------------------------------1. Application names not being translated in connkit
2. Ability to view Home Variables, CAS variables, App Variables, and App Files
3. Ability to add application icon to an application
4. Program editor uses monospaced font and has line numbers
New Functionality (Calculator Software)

geometric, negbinomial, uniform, weibull
2. Added more random generation functions: binomial, chisquare, fisher, geometric, poisson,
student
3. Added functions DDAYS, DATEADD, DAYOFWEEK
4. Added application variables AFiles, AFilesB and DelAFiles. Allows direct access of application
specific files

6. Added application variables AVars and DelAVars. Allows direct creation and access of
application specific variables
7. Applications now individually contained inside a directory structure to group variables and files
together
8. Sequence application can start at a location from 0-1000. Less stringent checking of recursion
to allow things like U1(U2(N-1))

21. Added clear confirmation on programs and note editor
New Functionality (Virtual Calculator)
-------------------------------------1. Ability to copy from 2D table/grid editor and paste to other programs like spreadsheets
Resolved issues and changes excluding CAS
----------------------------------------1. Resolved issue with local variable initialization in a program with using a complex number
2. Renamed “Program” and “Note” into “AProgram” and “ANote” to distinguish better from
variables “Programs” and “Notes”
3. Resolved issue with having a space before the #end in a #cas #end block
4. Resolved issue with local lists to allow local l= {{{1,2}}}; l(1,1,2);
5. Resolved issue with FOR STEP not rounding step calculation
6. Resolved issue with sqrt from catalog not placing cursor nicely
7. Improved setting/getting in stats using H1-H5, S1-S5
8. Resolved issues with the Instruction(n) command
9. Resolved issue where connkit causes emulator to not connect to streamer on connection if the
connkit was running

15. Resolved issues with INPUT command
16. Resolved issue with nested CHOOSE calls used from user key
17. Resolved issue with program catalog "RUN" button and terminal
18. Removed the H1Type-H5Type variables in Stat 1Var. Use H1(3):= to change plot type.
