The version must be a distinct number for each release candidate so nimble
resolves it independently (nimble versions are numeric — pre-release strings
like 0.2.0-rc.4 are rejected, and equal versions across git refs collide in the
cache). This 0.2.1 candidate carries {.ffiExport.} on top of the 0.2.0 line.
