I would like to point to importance of using revision number delimiter
(by convention we use letter "r"). This delimiter allows avoid
problems in case if upstream decides to make first release or uses
versions with different number of components.

e.g. if at revision "455" upstream decides to release version 0.1 then
the revision delimiter preserves version monotonicity:
0.1.r456 > r454
without delimiter monotonicity fails:
0.1.456 < 454

This is true for other VCS as well.
