Prestashop custom module routing issue after update to 1.7.8.4 - prestashop

Question

I just updated a PrestaShop website from 1.7.8.3 to 1.7.8.4, everything worked fine, but I'm havine 404 errors on custom module routes.
On module install I register routes like:
$this->registerHook('ModuleRoutes')
And my routes are like:
public function hookModuleRoutes() {
$urls = array(
'module-mymodulename-posts' => array(
'controller' => 'posts',
'rule' => 'posts/list',
'keywords' => array(),
'params' => array(
'fc' => 'module',
'module' => 'mymodulename',
)
),
...
);
return $urls;
}
Now www.mywebsite.com/posts/list returns 404.
And www.mywebsite.com/modules/mymodulename/posts works but url is not looking as good.
It all was working fine until this morning update.
Any idea on how I could get this solved ?
I have nothing about routing in the release logs.

Apparently a PrestaShop bug:
https://github.com/PrestaShop/PrestaShop/issues/27854
that just got a fix:
https://github.com/PrestaShop/PrestaShop/pull/27874/files
Fix works fine on my side.

You have to change getHookStatusByName function in classes/Hook.php file :
public static function getHookStatusByName($hook_name): bool
{
$hook_names = [];
if (Cache::isStored('active_hooks')) {
$hook_names = Cache::retrieve('active_hooks');
} else {
$sql = new DbQuery();
$sql->select('lower(name) as name');
$sql->from('hook', 'h');
$sql->where('h.active = 1');
$active_hooks = Db::getInstance()->executeS($sql);
if (!empty($active_hooks)) {
$hook_names = array_column($active_hooks, 'name');
if (is_array($hook_names)) {
Cache::store('active_hooks', $hook_names);
}
}
}
return in_array(strtolower($hook_name), $hook_names);
}
