Release Notes for ABCL 0.19.1

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.
Unprocessed command line arguments are collected in this variable for Lisp programs to use.
