For several weeks / couple of months i'd been running TB 49.0 Beta, with the associated Lightning version, & it was all good. Last week it began incessantly nagging me that there was a newer version available, but this initially puzzled me coz every time i checked here https://ftp.mozilla.org/pub/thunderbird/releases/ there was no newer version of the Beta, & i was [deliberately] in the Beta stream. Eventually i deduced that despite me being in Beta stream, it had been nagging me actually about the Release stream, & when i checked, indeed there was 45.4.0, which i duly downloaded, extracted, & moved into /usr/lib/. After starting it, Lightning was predictably disabled, but this was really no hassle as i simply installed the compatible version, & once again all is fine. Obviously i backed up my profile before doing this, but i did not need to revert to it as the process was entirely successful.
It was all pretty easy & straightforward. Whilst i'd prefer not to have to manage this myself, but rather leave it to the Repos, i wasn't willing to keep using the old 38.8 [which was why i'd jumped to the Beta, those weeks/months ago]. This is not a criticism of Maui Devs btw, as even when i was still using Mint 17.3 KDE, their Repos still only gave me 38.8.
