- 22:21 Feature #658: Indets actually in a poly (or vector or matrix)
- I have moved this issue to CoCoALib, which is where I had expected to find it.
On several occasions I would have l... - 22:04 Feature #987: GCD: add special case if args are monomials
- The relevant place in the code seems to be in @SparsePolyRing.C:814@.
To see how slow the current code is, try the... - 21:54 Feature #987 (New): GCD: add special case if args are monomials
- While trying to comprehend the (undocumented) code I wrote in @ArithGroup.cpkg5@, I noticed a comment about GCD being...
- 15:43 Design #764 (In Progress): ExternalLib: simplify configuration
- Is this now resolved? Or even in @feedback@? Perhaps change target version?
- 15:41 Bug #986: GFan: require version newer than 0.6
- Anders let us know by email (2016-11-28) about the problem in @gfanlib@.
I have already asked how a shell script c... - 15:38 Bug #986 (In Progress): GFan: require version newer than 0.6
- Anders reports that @gfanlib@ version 0.6 contained a bug.
We should either require that @gfanlib@ be newer than 0.6...

- 18:01 Design #983: Which ostream for verbose/obsolescent log mesgs?
- The standard ostream @clog@ would be the logical choice for logging messages (on a program that runs inside an xterm,...
- 17:53 Design #983 (Closed): Which ostream for verbose/obsolescent log mesgs?
- Which @ostream@ should be used for log messages produced by "verbose mode" or "obsolescent" warnnings?
Note that e... - 17:44 Design #982: Catching interrupts in example progs?
- Perhaps the current behaviour is not so bad: CoCoALib converts any interrupts that it detects into an exception of ty...
- 17:35 Design #982 (Closed): Catching interrupts in example progs?
- With the current design (where the exception produced by an interrupt is not of type @CoCoA::ErrorInfo@), if you inte...
- 17:30 Bug #971 (Feedback): CheckForInterrupt does not work in the expected way

- 13:56 Bug #154 (In Progress): GCD normalization (e.g. monic)
- I stumbled across this problem/issue again when trying to implement @GCDFreeBasis@ (see #259).
In reference to my ... - 13:19 Feature #259 (In Progress): Squarefree(?) GCD-free basis
- I have written a first version (for @RingElem@) by translating almost directly the impl in @GCDFreeBasis.cpkg5@. I h...

- 08:35 Feature #961 (In Progress): New function: ReducedGBasis
- 08:34 Feature #961: New function: ReducedGBasis
- I realized, after trying to implement it, that CoCoALib @myDoGBasis@ already does it!!
In fact the only operation no... - 08:25 Feature #931: GBasis verbose mode
- Now we have @SetVerbosityLevel@ it should be (almost) trivial.
- 08:23 Feature #962: General verbose mode?
- Added in CoCoA-5. Fantastic!

- 15:38 Feature #979: SmallestNonDivisor -- new fn
- I still like the idea of an iterator, but it would be hard to "export" the notion to CoCoA-5. Maybe that does not ma...
- 15:31 Feature #979 (Resolved): SmallestNonDivisor -- new fn
- Added *@SmallestNonDivisor@* to @NumTheory@; also available in CoCoA-5.
Updated doc for @NumTheory@.
Still to do: ... - 12:42 Bug #975 (Resolved): configure: possibly ignore GMP compilation flags
- I have added (yet another) configuration option *@--ignore-gmp-cflags@*.
Combining this with *@--with-cxxflags=@* sh...
