- 09:33 Slug #709: Speed of some Normaliz calls (NmzComputation)

- 09:27 Feature #912: Add TUTORIALs to online manual
- The situation has improved. Maybe I will get good feedback from the course here in Kassel (2021-10-12).
- 09:26 Feature #1246: Revive old CoCoA4 package called "cocoa5.cpkg"

- *2021-10-12* this is still a problem.
Presumably the problem comes from computing a multivariate gcd over a finite... - 09:12 Bug #1443: Illegal instruction

Possiamo semplicement chiudere l'issue? - 09:03 Feature #1415: thmproving package

- 12:13 Bug #1613 (Resolved): CRASH with RingHom from FrF
- Similar to issue #1614, I have "hacked" the interpreter, and the examples seem to work now.
But I am not confident t... - 12:11 Bug #1614 (Resolved): SourceRegion gives misleading error mesg
- I have rather blindly changed the interpreter. The code now seems to work as hoped (but I am not too confident that ...
- 11:57 Design #1615 (Rejected): apply: remove for RingHom
- *THIS IS REALLT A DUPLICATE OF #1598. SO REJECTING!*
- 11:16 Design #1615 (Rejected): apply: remove for RingHom
- As done for CoCoALib, permit RINGHOMs to be applied directly to LIST and MAT.
Then eliminate @apply@ (or make it obs...

- 22:42 Bug #1613: CRASH with RingHom from FrF
- Actually a separate bug: @CommonDenom(a*x^2-1/a)@ gives 1 rather than @a@... Ooops!
*NOTE* the code looks fine, ... - 22:35 Bug #1613 (Closed): CRASH with RingHom from FrF
- The following causes a crash: why was the exception not caught and handled?...

- 09:55 Bug #1610: IsInRadical: some more little bugs
- Error if *GradingDim* is 0 (lex, elim, ...) for call to *IsHomog*. Now fixed.
- 09:52 Bug #1610 (Closed): IsInRadical: some more little bugs

Usually, after isolating them, the solution is trivial.
List below.

- 22:37 Feature #1536 (Closed): Implement xel?
- 22:35 Bug #1215 (Closed): RationalSolve: gives "Error: must be non-zero"
- Closing this issue because there is no clear indication of what to test.
I suspect the new design of @RationalSolve@... - 22:32 Bug #1537 (Closed): EmacUI: strange colours, sometimes
- I have not seen the problem of unexpected colours for some time.
Reading through the notes suggests that Emacs's way... - 22:29 Bug #1574: ApproxSolveTF
- Probably @ApproxSolveTF@ should have an accuracy-check-loop the same was as was done for @ApproxSolve@:
the heuristi... - 22:26 Bug #1573 (Closed): ApproxSolve: very imprecise
- @ApproxSolveTF@ was surprisingly fast on the example given in the description (about 9s, vs 64s using @ApproxSolve@)....
- 20:34 Bug #1573: ApproxSolve: very imprecise
- I have just updated the manual entry for @ApproxSolv@.
I wonder what @ApproxSolveTF@ does... mmm??? - 22:21 Slug #1392 (Closed): ApproxSolve: another slow example
- 22:18 Bug #1539: Website: installation instructions for Microsoft
- With luck the current instructions will be well tested over the next couple of weeks.
I hope we can close this issue... - 22:16 Bug #1531 (Closed): CRASH: arithmetic with HilbertSeries (tagged object)
- There is already a test in *@exbugs.cocoa5@*
Closing after 11 months in feedback. - 21:58 Bug #713 (Closed): External libs: interrupting not easy

- This has been in feedback for 7 months.
I think we mention in the release notes that it is a backward INcompatible c... - 21:47 Feature #1293: Vim Plugin for CoCoA

- 13:04 Bug #1573: ApproxSolve: very imprecise

Is there a verbosity level which gives useful info? If so, document it (ri... - 12:40 Slug #1270 (Closed): RationalSolve: use MinPolyQuot instead of elim
