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, built-in keywords and
variables are all lowercase only
* Regularize case in printed messages
* Improved TeXmacs interface, 2-d 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 single-float
results instead of double-float 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.

developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
around at either build-time or at run-time is:
USE_TOOLS+= perl # build-time
USE_TOOLS+= perl:run # run-time
Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.
