Note: Due to issues in version 0.19.0, that specific
version was never released.
- Support for user-extensible sequences
- Support for the functionality proposed by Christopher Rhodes
at the International Lisp Conference 2007, user-extensible
sequences; these were provided by SBCL for a while now. With this
release, ABCL adds support too.
- Much better support for inlining anonymous and local functions
- Before, only functions with fixed numbers of arguments were
inlined when declared inline. Now, inlining also happens to functions
with &optional and &keyword arguments or &rest parameters.
- EXT:*COMMAND-LINE-ARGUMENT-LIST*
- Unprocessed command line arguments are collected in this variable for
Lisp programs to use.
