jit_expr is a clone of the pure data expr/expr~/fexpr~ objects. It just-in-time compiles its expressions so they should be much more optimized than the original. If all works as designed, they should use less CPU than the equivalent vanilla, non-expr, patching and have a significant CPU advantage over the original expr objects.

This release has no functional difference with the previous 0.1 release, and there is no update needed for Linux. All this does is support more versions of Mac OsX. The 0.1 release was built for 10.13.
Thanks go to Marco Matteo Markidis for doing this compilation!

I've put the external, compiled for 64-bit Mac-OS 10.10+, up on deken: in pd, go to help menu, find externals, search for "jit_expr", click on the 0.1.1 version to install. Unfortunately it shows up below 0.1 in the current implementation of "find externals" but an update has already been implemented for that for the future.

Please report any issues here:

I would still love help building Windows and 32-bit Linux versions of the externals.
