 * Fixed #203: Resolves an issue where packages that have `LinkingTo: later` (including `promises` and `httpuv`) and were built against `later` 1.4.0, would fail to load on systems that actually had older versions of `later` installed, erroring out with the message "function 'execLaterFdNative' not provided by package 'later'". With this fix, such dependent packages should gracefully deal with older versions at load time, and complain with helpful error messages if newer C interfaces (than are available on the installed `later`) are accessed. (#204)

+I'm so sorry to be re-submitting this so soon after my previous submission.
+That version (1.4.0) has started causing problems for deployed projects
+that use packages that link to {later}, like {httpuv} and {promises},
+because their CRAN binaries are built against the latest CRAN {later} but
+they may have pinned their locally installed {later} to an older version.
+This causes R_GetCCallable calls in those dependent packages to fail on
+package startup.
+
+This submission is intended to fix this problem by gracefully detecting the
+version mismatch, and simply not performing R_GetCCallable calls that will
+not succeed.
