This pair of new releases incorporates both the new (far more robust than the original) File::ShareDir implementation, as well as the new install_share command in Module::Install to go with it.
When using install_share for new releases, please make your dependency on File::ShareDir is set to 1.00 or higher to ensure you have the new implementation (Module::Install will not automatically add it, but may in the next release).
This release of Module::Install also includes a fairly large number of small to medium changes (see the Changes file if you are interested) but nothing that should be particularly explosive in nature.
I'll be around a lot over the next few days to keep an eye out for any fallout from these changes, so if you find something working wrong don't be backwards in coming forwards.
