Consistent versions

*This* one? No. But this commit isn't the one that's going to be tagged for release 4.3, and I assume you want this field's value to be consistent prior to the 4.3 release and also after the 4.3 release but prior to 4.3.1 (or 4.4). The release process involves two sequential commits:

1. The first commit replaces all instances of `4.x.y-SNAPSHOT` with `4.x.y` (or the actual release version, e.g. `4.2.3-SNAPSHOT` could be released as `4.3`)
2. The second commit increments the patch value of all version numbers and adds the `-SNAPSHOT` suffix back. For this release, it means replacing `4.3` with `4.3.1-SNAPSHOT`.
