Planning for the next PARI/GP release

Discussion of releases

There does not seem to be a need for unstable releases as a testing platform for stable releases. One option would be to make a snapshot release just before each Atelier, so that participants could download the corresponding binaries.

New features

• ECPP (Jared Asunción)
• LU decomposition of matrices (Peter Bruin)
• improvements for elliptic curves over number fields (François Brunault and Bill Allombert)
• algebraic lattices: qfauto and qfisom (tentatively, Thomas Camus)
• numerical summation of over integers or primes (Henri Cohen)
• work on plotting (Jeroen Demeyer)
• character tables of permutation groups (Aurel Page)
• compact units (Karim Belabas)
• complete documentation of all operators (Marine Rougnant)
• merge the existing t_REAL branches (?); remove incompatibility with polgalois (Karim Belabas)
• primepi (Dana Jacobsen)
• porting of Michael Stoll’s ratpoint script (Bill Allombert)
• Falting heights over Q and nf (Pascal Molin)

External projects

• Cython bindings for Pari (Luca De Feo and Jeroen Demeyer)
• more regular PariDroid releases, removal of the old project from Google (Andreas Enge)
