You have 3 options to handle this:

a) do not bump the assembly version and deploy the new version using
the same version number (can be seen as overwriting the old version)

b) bump the assembly version on each release (like you did) and install
policy files that map the old version number to the new one: e.g. to, that's a feature provided by Mono and .NET, see:

c) bump the assembly version on each release but don't install policy
files and recompile all applications that use that library.

I have to disagree, .NET for example does not accept private
but strong named libraries were the major number part was changed.

To my experience Mono is less strict than .NET when it comes to
versioning, also see the gacutil issues with delayed signing Mono had.
