## [New features]()

## Tasks

- [doctesting]()
- cypari2: Python interface to libpari [on Sage trac](https://trac.sagemath.org/ticket/20238) [on github](https://github.com/defeo/cypari2)
- [ECPP]()

- Jared Assuncion: doctesting + elliptic curve primality proving
  branch with a first implementation is available; certificates compatible
  with magma
- Peter Bruin: linear algebra over finite fields and over Z
  work in progress
- François Brunault: elliptic curves over number fields (ellisomat)
- Thomas Camus: lattices over alg. integers
- Giacomo Cherubini : doctesting + numerics on Kloosterman sums
- Henri Cohen: modular forms + numerical methods for summation
  small tasks from last year implemented: code and tests are there,
  documentation is in progress
- Christophe Delaunay: zeroes of L-functions elliptic curves
- Vincent Delecroix : compact orbits of SL_3(R)/SL_3(Z)
  first working program
- Jeroen Demeyer: plotting with output to SVG files: essentially finished
- Simon Drewitz : hyperbolic orbifolds
  change of plans towards a different, hopefully working algorithm
- Luca De Feo: cypari: Python bindings for PARI/GP implemented in Cython: essentially finished
  Sage preparations ready
- Andreas Enge: PARI-GNUMP
  gforge project available
- Jean-Pierre Flori: ell. point counting / ECPP
  contributions to Jared's project

- Paul Zimmermann: doctesting of elliptic curves

## 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)

### 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)
