OSTRICH version 1.3

This is the version of OSTRICH that competed at SMT-COMP 2023.
Compared to 1.2, there is now also a solver back-end based on cost-enriched automata, which can be enabled with the option +cea.

OSTRICH version 1.2

Version 1.2 of OSTRICH includes a module for solving general word equations (not restricted to the straightline fragment), as well as more complete support for the different SMT-LIB string operations.

OSTRICH version 1.1

This release includes a lot of work that has happened since 1.0.1, including a built-in parser for ECMAScript regular expressions, and techniques for handling regular expressions with capture groups. The release also includes many optimizations and bugfixes.

v1.0.1

This is a release with most bug-fixes. We also worked on the support for the new SMT-LIB string theory, and added several functions that were missing previously.
