Old pre-v0.15 changelogs (very likely stale and incomplete)

git version

• Support for %map.A.B.C syntax to use values from a specific module, rather than the one in scope.

v0.11

• Depend on ppxlib instead of (now deprecated) ppx_core and ppx_driver.

113.43.00

• Dropped Open_in_body support from ppx_let, since it was only ever used in confusing chains of Let_syntax modules that introduced other Let_syntax modules in the "body" (e.g. for defining Commands whose bodies use Async). In this case it was decided that the better practice is to be explicit with open ___.Let_syntax at the different transition points, even though this is more verbose.
