Yes, those lines changed have changed in the version available for download at www.remarpro.com, without the overall version number changing.
Really, Wordfence needs to change its algorithm, because it’s a false warning. Lots of plugins (I speak as someone who manages approximately 100 WordPress websites and uses change management tools to monitor them) release small changes without bumping their version numbers. The problem with bumping the version number is that it shows an update to everyone, and that may annoy more users than it helps, especially if the change is small. Wordfence needs to adapt to this situation, which isn’t likely to change (it is widespread across many plugins) and stop giving the false warnings when it happens. Wordfence could monitor the changes in versions available at www.remarpro.com, instead of assuming that if the version number hasn’t changed then nothing else has changed.
