It looks like the sqlite fixes / improvements (to get it ready for stable?) are being pushed in, thanks to the effort of sss123. Many new commits happening quite often recently, so I suppose it might be ready soon. As a note, the old sqlite and new (after current rework) sqlite plugin will not be compatible so it is highly recommended that if you are using the old sqlite at the moment, migrate it to libmdbx (make sure to have backups at every step), and then back to sqlite after upgrading miranda.
The time for that has not come yet though, I suspect there will be an official word from the likes of Ghazan or Dartraiden when this is the case.
