TI-84 Plus CE / TI-83 Premium CE - Version 5.3 - Changelog
(Cross-posted from TI-Planet)

Thanks to TI, we've been able to try OS 5.3 in advance and so we've made this unofficial changelog for you, although you've probably seen some of those things in our recent news



1) Homescreen:
Improved program launching:

• archived programs directly
  
• assembly programs directly
  
• sub-programs (asm and/or archived) OK

More info: https://tiplanet.org/forum/viewtopic.php?f=41&t=20147



2) Programming and editor:
New :f31: :f15: menu with options:

• Launch the current program
  
• Undo erase
  
• Inserert blank line above
  
• Cut current line
  
• Copy current line
  
• Paste line below
  
• Insert a "comment" (watch out: " inserted, = a string)
  
• Quit

3) Mathematics:
Textbook-like render of piecewise functions

New menu with several pre-written conditions to help write these functions.


Ability to input related sequences of different types

4) Apps:
Application Transfrm (Transformation Graphing) :

• Reminder of the graphs' precisions (resolution): 3 for animations, 1 otherwise
  
• Y1 and Y2 only are available for the app (instead of all)
  
• 11 equation templates in the editor:
  
  • A*X+B
    
  • A*X²+B
    
  • A(X-B)²+C
    
  • A(X-B)(X+C)
    
  • A*X²+B*X+C
    
  • A(X-B)3+C
    
  • A*X3+BX²+C*X+D
    
  • A*abs(B(X-C))+D
    
  • A*sin(B(X-C))+D
    
  • A*cos(B(X-C))+D
    
  • A*tan(B(X-C))+D

5) Misc.:
Transfers: "Resend" option in the menu



6) TI-Connect CE 5.3:
Distribution of version 5.3 as a "Bundle" file containing:

• Default apps (in the apps menu)
  
• Language apps (mode menu)
  
• Hub app(for the TI-Innovator)
  
• Defaulg images

7) TI-SmartView CE 5.3:

• Improved emulation speed(but low FPS = jerky graphs)
  
• Saving/Loading of emulation state
  
• Ability to update the emulator's OS

In conclusion, some very good things
It's available very soon, for the 2017-2018 Back-to-school season !

This is wonderful, I think it's about time they made it possible to execute archived and asm programs hassle free, its very confusing for someone who doesn't know much about graphing calculators, which is the vast majority of the world .
I'm also quite a fan of the piecewise functions, which could only be achieved by adding some statements that would render the function undefined on desired intervals. It's nice to see that there will now be a built-in/more kosher way to do it.
All in all, a step in the right direction from TI.

Has anything changed that would make current programs not work?

I had heard vague rumors about this for sufficiently long enough that I'm really glad it's going to be in the next OS version. As we've shown with all of our various shells like NoShell and Doors C[S][E] it's eminently feasible to run archived and/or ASM programs directly from the homescreen, and it's excellent that these are now built-in features that will help prevent new users from getting confused. The next thing I'd love for them to incorporate is an actual comment token (like //) instead of the performance-impacting "COMMENTS.

Wow I can't believe my eyes is this for the ti 84 plus CE too

Yes it is!

can't wait

wow, these are features that should have been there a long time ago, IMO. I especially like the editor features, which I use all the time in zstart.

I'm ery sad that the app SDK you joked about on IRC is just that: a joke

I don't think so; after all, they're only adding things, not changing what some pieces of code do.
