Trying to fix packagist

on GitHub

  [Composer\Repository\RepositorySecurityException]                                                       
  The contents of https://packagist.org/p/provider-latest%240cbfb40ab72a881d21b70f78286d39cd72e3b0eb8704  
  c13e79dc49624e549973.json do not match its signature. This should indicate a man-in-the-middle attack.  
   Try running composer again and report this if you think it is a mistake.  

I'm releasing this new version in the hope that everything works again
