Version 0.6.2, "Capsicum", released in June 2021, comes with the following new features:

• Bug fixes
  • Correct a bug that prevented the reconstruction of real towers when no real conjugate is present.
  • Correct a memory leak in mpcx_tower_clear.

Version 0.6.1, "Capsicum", released in April 2021, comes with the following new features:

• Bug fixes
  • In mpfrcx_tower_decomposition, correct the check whether a relative minimal polynomial is real or the complex conjugate of another one.
  • In mpfrcx_tower_decomposition and mpcx_tower_decomposition, prevent its arguments from being modified by the recursion; for the former function, this could cause access to non-initialised variables and was a real bug.

Version 0.6, "Capsicum", released in August 2020, comes with the following new features:

• New functions mpfrx_eval and mpcx_eval for evaluating polynomials in a single argument using a Horner scheme; this complements the existing functions mpcx_multieval and mpfrx_multieval.
• New convenience functions:
  • mpcx_mul_c, mpcx_mul_fr, mpcx_mul_si, mpcx_mul_ui, mpfrx_mul_fr, mpfrx_mul_si, mpfrx_mul_ui for multiplying polynomials by constants of various types
  • mpcx_mul_x, mpfrx_mul_x for multiplying by powers of the variable
• Bug fix: Make mpcx_multieval and mpfrx_multieval work with polynomials of degree 0 or 1.

Version 0.5, "Duroia", released in May 2018, comes with the following new features:

• Licence change: LGPLv3+ for code, consistent with GNU MPC and the other libraries of the GNU multiprecision universe
• New simple functions
  • mpcx_set_frx
  • mpfrcx_real and mpfrcx_imag
  • mpcx_derive and mpfrx_derive
• New convenience functions for handling trees of polynomials, where the leaves are linear polynomials derived from a root, or quadratic real polynomials derived from a pair of complex-conjugate roots
  • mpcx_reconstruct_from_roots, mpfrx_reconstruct_from_roots and mpfrcx_reconstruct_from_roots
  • mpcx_subproducttree_from_roots, mpfrx_subproducttree_from_roots and mpfrcx_subproducttree_from_roots
  • mpcx_hecke_from_roots, mpfrx_hecke_from_roots and mpfrcx_hecke_from_roots
  • mpcx_product_and_hecke_from_roots, mpfrx_product_and_hecke_from_roots and mpfrcx_product_and_hecke_from_roots
• New functions for decomposing certain number fields into towers
  • mpcx_tower_init, mpcx_tower_clear, mpcx_tower_decomposition for decomposing Galois fields into towers of relative extensions; this can be used for class fields of imaginary-quadratic fields
  • mpfrx_tower_init, mpfrx_tower_clear, mpfrcx_tower_decomposition for decomposing the real subfields of class fields of imaginary-quadratic fields into towers of relative extensions

Version 0.4.2, "Cassava", released in May 2013, comes with the following new features:

• New function product_and_hecke
• Improved memory consumption for unbalanced FFT multiplications

Version 0.4.1, "Cassava", released in July 2012, comes with the following new features:

• Switch to GNU MPC version at least 1.0
• Reduced memory consumption in hecke

Version 0.4, "Cassava", released in February 2012, comes with the following new features:

• New functions
  • tree_init, tree_clear, tree_get_root
  • subproducttree
  • hecke
  • swap
• Bug
  • corrected computation of required buffer for Toom-Cook
• Changed function
  • reconstruct: removed verbosity parameter introduced in version 0.3

Version 0.3.1, "Banane", released in September 2010, comes with the following new features:

• adaptations to build on MacOs X

Version 0.3, "Banane", released in June 2010, comes with the following new features:

• Function init2 renamed to init
• Changed function
  • reconstruct takes an additional verbosity parameter
• New functions
  • set_deg, set_prec, set_coeff
  • get_coeff
  • get_version

Version 0.2, "Ananas", released in May 2009, comes with the following new features:

• Support for autotools (thanks to Philippe Théveny)
• Single header file mpfrcx.h instead of two separate ones, mpcx.h and mpfrx.h
• Function init2 renamed to init
• New functions and macros
  • get_deg (macro)
