Everyone please keep in mind that the new version might still behave badly for a handful of people, but it will have eliminated the issue of utf-8 settings file corruption (if known, good INIs are started with). That should allow us to focus on the general (but seemingly not pervasive) performance issues. Especially ones reported by @RbnJrg where the new Sigil behaves badly all the time, right out of the gate.

Everyone should always keep good backups of their preferences just in case, but hopefully moving forward, we can get back to guaranteeing that there is no risk in upgrading Sigil (or rolling back to previous versions) when existing preferences are in place.
