10:17 Feature #202 (Closed): MatrixView/function for viewing a single row or column (RowMat, ColMat): We should make a special view for a row or column since the C++/STL for calling *submat* is so bad (vector containing... Anna Maria Bigatti
11:20 Feature #203 (Closed): Function to get the Hilbert Polynomial ring from GlobalManager: The function *MakeGlobalHPPowerList(const DenseUPolyRing& P)* in GlobalManager.C creates a list of polynomials.
Its ... Anna Maria Bigatti

15:09 Feature #40: Squarefree factorization - Alessio d'Ali`: Alessio has:
* continued with the report
* reorganized the tests so that they are largely automatic
He will chec... John Abbott

12:47 Bug #196 (New): PPWithMask needs checking: which functions give guarantees and which don't?
better be more clear and consistent.
Check also if PPMonoidFast ca... Anna Maria Bigatti

16:38 Bug #190 (Closed): Subtle ref count bug for poly rings (via CoeffEmbeddingHom): The function below looks perfectly reasonable, but it creates a *dangling reference*... John Abbott

16:11 Feature #157: Separate ThreadsafeCounter from symbol.C: Yes, in its current form it requires BOOST.
I can add some *@#ifdef@* directive to make it compile without BOOST (an... John Abbott
11:31 Feature #157: Separate ThreadsafeCounter from symbol.C: Does this mean that users are now forced to have boost, or we can have a non-threadsafe version without boost?
