Notable changes in FriCAS 1.1.6 (compared to version 1.1.5):
- Added experimental graph theory package.
- Added power series expanders for Weierstrass elliptic
functions at 0.
- New functions: kroneckerProduct and kroneckerSum for matrices,
numeric weierstrassInvariants and modularInvariantJ, symbolic
Jacobi Zeta, double float numeric elliptic integrals.
- New domains for vectors and matrices of unsigned 8 and 16 bit integers.
- Changes to Spad compiler: underscores which are not needed as escape
are now significant in Spad names and strings, macros with parameters
are supported, added partial support for exceptions, braces can
be used for grouping.
- A few speedups.
- Reduced disc space usage during build.
Bug fixes, in particular:
- Fixed eval of hypergeometricF at 0
- Fixed problem with scope of macros.
- Worked around problems with openinig named pipes in several Lisp
implementations.
- Fixed a problem with searching documentation via HyperDoc.
- Fixed build problem on Mac OSX.
Notable changes in FriCAS 1.1.5 (compared to version 1.1.4):
- Added numeric version of lambertW.
- New function 'rootFactor' which tries to write roots of products
as products of roots.
- 'try', 'catch' and 'finally' are now Spad keywords.
- Experimental support for using gmp with Closure CL (64-bit Intel/Amd
only).
- New categoris CoercibleFrom and ConvertibleFrom. New domain
for ordinals up to epsilon0. New domain for matrices of machine
integers. New package for solving linear equations written as
expressions (faster then general expression solver).
- Functions exported by Product() are now called 'construct', 'first'
and 'second' (instead of 'makeprod', 'selectfirst' and 'selectsecond'
respectively).
- Some functions are now much faster, in particular bivariate
factorization over small finite fields.
- When using sbcl FriCAS now tries to preload statistical profiler.
Bug fixes, in particular:
- Fixed handling of Control-C in FriCAS compiled by recent sbcl.
- Fixed HyperDoc crash due to bad handling of '#'.
- Fixed power series expanders for elliptic integrals.
- Fixed 'possible wild ramifcation' problem with algebraic
integrals.
- 'has' in interpreter now correctly handles '%'.
- Spad compiler can now handle single '=>' at top level of a function.
- Fixed few problems with conditional types in Spad compiler.
Notable changes in FriCAS 1.1.4 (compared to version 1.1.3):
- New domains for combinatorial probability theory by Franz Lehner.
- Improved integration of algebraic functions.
- Initial support for semirings.
- Updated framework for theory of computations.
- In Spad parser '**', '^' and '->' are now
right-associative.
- Spad parser now longer transforms relational operators.
- Join of categories is faster which speeds up Spad compiler.
Bug fixes, in particular:
- Retraction of 'rootOf' from Expression(Integer) to AlgebraicNumber
works now.
- Attempt to print error message about invalid type no longer
crash (SF 2977357).
- Fixed few problems in Spad compiler dealing with conditional exports.
- HyperDoc now should find all function descriptions (previously
it missed several).
