Installed the 05 beta 4, and the only new thing i see is that when you place your cursor in the the search box in the Search window, then the "words to search for" tool tip pop us covers where you type, so you cannot see what you are typing, which for me i like to see. It does not seem like the previous versions acted like that. Of course, moving the cursor away results in the tool tip going away.
BTW, the abbreviations discussed before for books Romans and Revelation Thessalonians (rm, rv, ths) are not yet added to the bpbible.conf file, but again this is no real issue.
May God give you grace and help. (cf. Ps. 138:8)
