• Laravel Version: 5.1.*
• PHP Version:all

Description:

many package require nikic/php-parser v3 and on v5.1 we cant install pacakge that need it

v0.8 of psy/psysh support v3 (v5.3 allready support v0.8)

many package require nikic/php-parser v3

Packages should attempt to support multiple versions of php parser instead of just mindlessly upgrading.

Yeh, though that's technically a new feature, and 5.1 is "LTS". We could technically support it I guess, but we don't want people complaining that stuff broke.

psysh is used for tinker so used in dev environment i think there is no problem in production environment

But niche developer might have other requirement to use psysh in their project, which still could cause issues.

I wouldn't recommend starting a project on Laravel 5.1 LTS. It's designed to give slow moving apps bug fixes and security assurance. It's not designed for people to be moving quickly with brand new packages. For these reasons, it's important that we do not brake the 5.1 branch with unneeded upgrades.
