Composer 2.8.7 breaks "rc" releases because of updated regex pattern #12364
Description
My composer.json:
{
"name": "opl/opl_about_profile",
"description": "OPL About site.",
"type": "project",
"license": "GPL-2.0-or-later",
"homepage": "https://www.drupal.org/project/drupal",
...
"autoload": {
"files": [
"load.environment.php"
]
},
"version": "1.0.0-rc.8"
}
When I run this command:
composer install
I get the following output:
In Factory.php line 317:
"./composer.json" does not match the expected JSON schema:
- version : Does not match the regex pattern ^v?\d+(\.\d+){0,3}(-(dev|(pat
ch|p|alpha|a|beta|b|RC)\d*))?$|^dev-.*$
And I expected this to happen:
Run the install without error.
The regex doesn't match on the version string anymore with "rc.1" and seems to require it to be "RC.1" instead now? It worked fine in 2.8.6 but in 2.8.7 it's now enforcing some new semver rule?
