7.2 because it has all we need for the next two years (7.3 doesn't provide anything we absolutely need, and 7.4 is not even released so cannot be considered yet.)

7.2.9 because of https://tracker.debian.org/pkg/php7.2

Needs:

• Allow Symfony 5.0 security-acl#48
• Allow Symfony 5.0 doctrine/orm#7723
• Allow Symfony 5.0 doctrine/DoctrineBundle#975
• Allow Symfony 5.0 doctrine/DoctrineCacheBundle#158
• Allow Symfony 5.0 #31657

Why not 7.3?

[nicolas-grekas]

The question is more: why 7.3?
7.2 is better for adoption.

[ciaranmcnulty]

Typed private properties would be a good driver for 7.3 I think?

edit: d'oh that's 7.4

[nicolas-grekas]

@ciaranmcnulty don't you talk about 7.4? See https://www.php.net/releases/7_3_0.php

I'd be in favor of PHP 7.3 too as 7.2 active support ends on November, 30 2019, so at the same time Symfony 5.0 will be released.

Since 7.4 will happen at the same time as sf5, it is probably too early to make that a minimal?

[nicolas-grekas]

7.2 is all we need to start working on Symfony 5.0.

[ciaranmcnulty]

@nicolas-grekas you are of course right. I forgot 7.3 had so few compelling features (some nice stuff but nothing that would require it over 7.2)

[vudaltsov]

Okay, I agree that as a minimum version 7.2 is good.

[lyrixx]

I'm for 7.2 too. 7.3 does not bring so much nice features. 7.2 seems better for adoption.

[Tobion]

👍 7.2 for now. Ref. #24283
Maybe bump to 7.4 later if released in time. Then we would use the latest PHP version like done with SF 4.

[alcaeus]

7.2 is a good choice for now: it allows strict typing, allows for parameter type widening in implementations (which is necessary during a migration to strict typing) and it has been widely adopted.

7.3 on the other hand lacks clear features that make it stand out, and 7.4 will not be released in time to be considered at all.
