Using the bbPress 2.6-alpha since one year without any problem but now the Wordfence alert me differences between the original version of the files and the installed version on my site.
Like this:

Do I need any update or why these alert messages?
Thanks for help!

This is because you’re actually using an old version of bbPress 2.6. bbPress 2.6-RC3 is published on the WP.org plugin repo (although it’s a bit hard to find with the new design), so WordFence is using those files as the comparison. These are legitimate file changes, and I would recommend updating to 2.6-RC3. Below is the official download link
