FriCAS 1.2.3 has been released

FriCAS is an advanced computer algebra system. Its capabilities
range from calculus (integration and differentiation) to abstract
algebra. It can plot functions and has integrated help system.
FriCAS 1.2.3 builds on Linux and many Unix like systems (for example
Mac OSX). FriCAS is build on top of Common Lisp; several Lisps can
compile and run FriCAS -- currently supported are GCL, SBCL, Clisp,

Notable changes (compared to version 1.2.2):

- Improved integration in terms of 'Ei' and 'erf'.

- Classical orthogonal polynomials may be used as expressions.

- More cases of generalized indexing for two dimensional arrays.

- Value of 'lambertW' at '-1/e' is now simplified.

- FriCAS now knows that formal derivatives are commutative.

- 'setelt' is renamed to 'setelt!'.

- ')read' now creates intermediate files in current directory.

- Continuation characters in comments are now respected.

- In Spad '$Lisp' calls now must have a type.

- In Spad 'error' did only minimal checking of its argument.
Now argument to 'error' must be a String or OutputForm
or a literal list of OutputForm-s.

Bug fixes, in particular:

- Input lines with empty continuation are no longer lost.

- Types like "failed" now consistently use string quotes in output form.

- Fixed pattern matching using '%i' in patterns.

- Fixed ')display op coerce'.

- Fixed ')version' command.

- Fixed crash when printing '%'.

- Fix a buffer overflow in HyperDoc.

- Fixed HyperDoc errors in 'Dependants' and 'Users'.

- HyperDoc browser better handles constructors with parameters.
