My apologies if you get this message more than once, but there's a 
somewhat unusual situation in gretl development right now.
We've introduced a number of quite ambitious changes since the 2022b 
release, and despite our best efforts at testing these seem to carry 
some risk (including the risk of gretl crashing in some cases).
Temporarily, therefore, I've introduced a distinction between what 
we might call "mainline" updates (pure bug fixes and other innocuous 
things) and "bleeding edge" updates (promising speed-up of some 
functionality but, for now, risky).
Until further notice the gretl "master" git branch will be the 
mainline, and snapshots for Windows and Mac will be produced from 
it. If you're building gretl yourself and wish to experiment with 
the bleeding edge, please use the "more_compilation" git branch.
We don't expect this bifurcation to last for very long: as they say, 
"Normal service will be resumed as soon as possible".
