Release 0.24.0 - June 21, 2022

Release 24.x is a maintenance release. A lot of changes happened between 0.17.0 and 0.23.x, so if you have not looked here for a while, go to the release notes for 0.23.x

• ParseTree::parser and ParseTree::parsers now generate parsing closures that do not need a JVM lock to synchronize on the Evaluator anymore.
• Also both functions now capture the generated Class<?> instance instead of a handle to the grammar, for efficiency’s sake
• The interpreter’s implementation of concrete syntax does not do its own parser caching anymore. Instead it relies on the aforementioned parsing closures. This saves memory (fewer hash-tables) and also more sharing is possible between parsers for different modules that happen to have the same grammar.
• Issue #1615 was solved
• Issue #1614 was solved
• Issue #1613 was solved by providing loc based interfaces to files and programs passed to util::ShellExec. The old str based interfaces are now deprecated.
