Development Discussion Board

Confirmed. It seems that this change is the cause https://github.com/phpbb/phpbb/pull/6549.

EDIT: suggested fix https://github.com/phpbb/phpbb/pull/6709

Personally, I'm almost sure phpBB4 won't get new style (just because its development status is null, and yes, if you say about Chameleon - it's not a style but a framework).
So adjusting Prosilver is definitely not a waste of time.

PostgreSQL 9.3 or above I'd rather go with PostgreSQL 9.4 or above as 9.4 has differences in syntax, f.e. supports Empty SELECT lists and probably other things. What is more important that Doctrine used in phpBB 4.0 only supports PG 9.4+ 8-) MariaDB 5.5 or above 10.2 (10.2.7 GA) and above for the s...

This patch https://github.com/phpbb/phpbb/pull/6350 should fix installing extensions stuff.

This very board is phpBB4-dev live.

Chameleon-based style, if ready during phpBB 4 times, could be attached later with some minor 4.x release (or even mark it 4.1 because of that if needed). 4.x needs some more work currently, mostly important as for me a...

Noone restricts style developers to Chameleon framework. If there're people who wants to create bootstrap-based phpBB style, they're free to create pull request and do that right now. But there're no such people around, so the conclusion about "more people could participate in the bootstrap&quo...

This poll is pretty useless because there're no frontend developers standing at the start line and waiting for the poll results to go implementing them asap. There's only 1 phpBB frontend developer who's implementing what he thinks right and he's not going to do what the poll will say. So, anyone is...

Makes sense. Is there a ticket for that?

Personally, I don't see how phpBB registration is more complex than the screenshots above.
