Another option to consider is splitting the version numbers such as: JDBC3 --> org.commons.apache.commons-dbcp-1.3.0 JDBC4 --> org.commons.apache.commons-dbcp-1.4.0
Unless you have expectations to continue supporting JDBC3 in the next major release, I would seriously suggest a version bump. The typical use case of major version bumps are incompatibilities. PS: You could also try splitting 1.3.0 / 1.3.5, but you would have to bring in a 4 digit for patch releases -- to avoid 5 1.3.0 patches incrementing to 1.3.5.
