I'm a little bit confused by this software update.

I downloaded the link for G1 Here

G1: https://www.hpcalc.org/details/7469
G2: https://www.hpcalc.org/details/7783

I installed it on my G1.

The top of the release notes, I mean these are the top release notes, highest, assumedly latest, even if the date of update isn't correct, is should be October, right?:

Description
-----------
This release of the Prime Calculator firmware and associated PC and Mobile 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.

Primary focus of this release are an update of the CAS, an update of the programming environment, the addition of the Python language, intelligent math and changes for the Netherland.

New features:
1. Add intelligent math to return limited symbolic results in home screen (can be disabled in exam mode)
2. Add Python app
3. Add more programming features
4. Detect sin(n*PI), cos(PI/2) and TAN(PI/2) in home mode (returns 0 or error)
5. Allow customization of a b/c keys results (can be disabled in exam mode)
6. Add a probability wizard to the toolbox/math/proba menu
7. Add a polynomial root wizard in the toolbox/cas/polynomial menu
8. Add Torque units
9. Add save/load of work in home
10. Add triangle surface calculation in triangle solver
11. Solve app: one can enter equations that use undefined variables. It will ask if and where they need to be created
12. Allow ifactor and similar function to be disabled in exam mode math/numbers
13. Cas median, quartile and mean functions are now disabled when Do1VStat is disabled in exam mode
14. Cas regressions fuctions are now disabled when Stat2Vars is disabled in exam mode

Cas change:
1. fix bisection solver
2. fix for derivative evaluation and for solve
3. fix for solve(22044=6000+264*((x+1)^(60)-1)/(x)*(1)/((x+1)^(60))+7000*(1)/((x+1)^(60)))
4. fix for solve([x*y^3=10^11,x^2/y=10^8],[x,y])
5. fix for solve(exp(x)=x+1)
6. fix for usimplify, e.g. usimplify(1_W*1_s)
7. fix matrix reduction/inverse for approx matrices with mixed real/complex entries
8. fix parsing of %%
9. fix potential overflow in ichinrem
10. gbasis memory alloc fixes
11. implicit declaration as global variables of variable names in optional assignation of arguments
12. improve factor(x^5-1) if sqrt is checked
13. improved precision for normald_cdf with negative arguments
14. improvement for integration of normald(x)*normald_cdf(x)
15. increase default number of steps for bisection solver
16. patch for limit(((sin(x))^(2))+((cos(x))^(2)),x=inf)
17. some list processing for polar/rectangular_coordinates
18. avoid infinite loop for desolve(y'=((-((y)^(3)))+((51)*((y)^(2))))-(((5/100))*(y)))
19. fix for piecewise conversion if one test is true or false
20. optionnal arguments left, right, center, tail for normald_icdf (also for Student, Fisher and Chi Square)
21. texpand improvement for texpand(tan(pi/2-x))

fixed bugs:
1. no more reset in spreadsheet if goto and no entry
2. Most Geometry app display should follow the Number Format
3. #FF:64 edition in base was incorrect...
4. (2_s)^-1 gave a wrong result!
5. ABS(1/3+1/3+1/3) was not 1
6. RPN sequences were not evaluated when executed in dialog boxes or spreadsheet
7. could not integrate between F1 and F2=dF1(X)/X=X
8. crash if trying to user assign ON+ combination
9. crash in user keys when switching views
10. create help program from the program editor yielded a crash upon escape from newly created program
11. drawing X^(2/3) did not show anything in negative
12. edit mat, in readonly mode, did not display correctly the user selected title.
13. entering a bad RPN command (like 1+2) in 2 var stat column caused a crash...
14. paste of a quoted " did not work

So, back to which one doesn't work on mines.

That contained (fixed bugs):

5. ABS(1/3+1/3+1/3) was not 1

But I can definitely tell you, that if I type (and I use the little vertical line instead of ABS, yeah?)
ABS(1/3+1/3+1/3) and then hit Enter, then I get the result of 0.9999999999.

Was that not one of the fixes?

Point 5 should have sorted out for me:
