Significant changes from Maxima 5.9.1 to 5.9.2,
in no particular order.
Magnitude of changes varies widely.
* Parser is now entirely case sensitive, builtin keywords and variables are all lowercase only
* Regularize case in printed messages
* Improved TeXmacs interface, 2d input
* Moved nset (finite set functions) into Maxima core
* Ported Mersenne twister rng to Maxima core
* English reference manual revised (form and content)
* Reference manual translated to Spanish and Portuguese
* Additional tutorial documents
* Discrete plots (for plot2d)
* Enhancements to tensor packages (Atensor, Ctensor, Itensor)
* Replaced Airy functions with much more extensive implementation
* Revisions to Bessel functions
o Bessel functions with real order and complex argument can be evaluated numerically.
o bessel_j can be computed for negative real order.
* Revisions to gamma function
o Gamma function can be numerically evaluated for complex arguments.
* Revisions to elliptic functions
o Bugs 1165488 and 908185 fixed.
o Fixed issue where many of the routines were returning singlefloat results instead of doublefloat when given rational args.
o elliptic_f with complex args can be numerically evaluated.
o Other inverse Jacobi routines can be evaluated at complex points.
* Extensive revisions to hypergeometric functions
o Adjusted routines to return the new names for the Bessel functions (like bessel_j instead of %j).
o Similarly, any orthogonal polynomials now use the naming conventions used by the specfun orthogonal polynomial package.
o Corrected many errors in implementation.
o Some missing internal functionality added.
o Bug 1155241 fixed.
o Bug 1097915 fixed.
o Branch cuts for various relationships between hypergeometric functions and Legendre functions were implemented or corrected.
* Revised kill function (fixed several bugs, helps test suite run correctly)
* Revised code to run test suite
* Display noun forms 'for and 'if correctly
* Display if  then  elseif correctly
* Adjust placement of newlines between output lines
* Establish configuration variable *MAXIMATEMPDIR*, make use in plotting
* Cleaned up autoload declarations
* Source code lowercase
* Regularize use of packages in Maxima core
* Misc code cleanups incl. sloop > ANSI loop, rename private let and let*
