Still no progress yet today in https://area51.phpbb.com/phpBB/viewtopic.php?p=272331#p272331 it was announced "However, 3.1.3-RC1 is close to being finished and will be wrapped in the next couple of days:"
If I had the phpBB coding skills I would undertake to fix this problem, but sadly I don't and therefore I must depend on the phpBB development team to get this resolved.
As I've repeatedly stated, this is a significant regression from phpBB 3.0.12 which effectively renders the search function useless for wildcard searches and therefore is a blocking issue for updating any of my sites. Is this viewpoint incorrect? If not, why hasn't the Priority been changed?
Apologies if this seems a bit of a rant, but the silence from the development team has been deafening.
