<<<<<<< HEAD
=======
### [1.7.2] 2020-12-03

  * Fixed: Allow installing on php 8

### [1.7.1] 2020-09-27

  * Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases
  * Fixed: normalization of beta0 and such which was dropping the 0

### [1.7.0] 2020-09-09

  * Added: support for `x || @dev`, not very useful but seen in the wild and failed to validate with 1.5.2/1.6.0
  * Added: support for `foobar-dev` being equal to `dev-foobar`, dev-foobar is the official way to write it but we need to support the other for BC and convenience

### [1.6.0] 2020-09-08

  * Added: support for constraints like `^2.x-dev` and `~2.x-dev`, not very useful but seen in the wild and failed to validate with 1.5.2
  * Fixed: invalid aliases will no longer throw, unless explicitly validated by Composer in the root package
