18:04 Feature #992: Poly ring homomorphism to change ordering: This may be just a special case of "extending a PPMonoid homomorphism" to a poly ring homomorphism.
It could also ... John Abbott
17:05 Feature #992 (New): Poly ring homomorphism to change ordering: It could be helpful to have an easy way of mapping from one poly ring to another which just changes the term ordering... John Abbott

10:30 Feature #931: GBasis verbose mode: Added first verbosity comments activated with... Anna Maria Bigatti

09:13 Feature #961: New function: ReducedGBasis: the GBasis is not reduced if the ring is not commutative
(ideal(x,dx) is homogeneous, so the algorithm does not expe... Anna Maria Bigatti

21:47 Feature #765 (In Progress): ExternalLib-CDD: (needed by GFan): Here are some notes I have just made (after trying to compile CDD and GFan on my netbook).... John Abbott

19:30 Design #932: CoCoALib configuration: BOOST dependency: I have added a *@--no-boost@* option to the @configure@ script; this disables automatic searching for the BOOST heade... John Abbott
19:24 Design #932 (In Progress): CoCoALib configuration: BOOST dependency: The CoCoA @configure@ script complains if someone specifies "with Normaliz" but "without BOOST". The code in CoCoALi... John Abbott

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... John Abbott
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... John Abbott
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... John Abbott
15:43 Design #764 (In Progress): ExternalLib: simplify configuration: Is this now resolved? Or even in @feedback@? Perhaps change target version? John Abbott
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... John Abbott
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... John Abbott

17:40 Feature #765: ExternalLib-CDD: (needed by GFan): I tried to put GFan on the Linux box in Kassel, but did not succeed in getting CDD properly installed.
Part of the p... John Abbott

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,... John Abbott
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... John Abbott
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... John Abbott
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... John Abbott
17:30 Bug #971 (Feedback): CheckForInterrupt does not work in the expected way: John Abbott

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 ... John Abbott
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... John Abbott
