No. They are all at the same version number 2.14.12.
The release number is not an indication of it being ahead or behind any distribution. It is a number unique to the distribution itself and in no way relevant when comparing to anything outside of that distribution.
Also Solus is at release 41 of pidgin not 4.
Name : pidgin, version: 2.14.12, release: 41
Any time we touch any package in any way shape or form in the repository its release number MUST be incremented otherwise nothing is changed in the package provided in the repository nor would your PC know if a update is available compared to what you have installed.
So if we patched a bug, rebuilt it due to a dependency change, changed our mind about what features are enabled in the package, what optimisations are done to it, updated to the latest version, reverted to a previous version due to issues with the latest version etc etc the number is incremented. Which is why I said you can ignore it, it will mean nothing to the average user but is important to how distributions function.
