This is a collective thread for things that need to be done before the official release of 1.0.0

• maintenance cli command for removing not used dist files for private packages
• logs rotation
• upgrade guide
• atomic deployment with ansible playbook (⚛️ Implement atomic deployment with ansible playbook #241)
• update to Symfony 5.1 ⚠️ (Update Symfony to 5.1 #248)
• simple REST API (Feature request: REST API to manage packages #114, REST API implementation #255 )
• ability to search the package list (Package search #259, thanks to @giggsey)
• return sha sum for better performance (Proxy considerably slower than Packagist #261)

• add help to generate rest api token form
• add link to docs or some kind of hint in api tokens list
• add organization prefix to all api endpoint with organization param
• add better response for PUT api/{organization}/token/{token} endpoint (maybe just like in create token)
• add list and create organization endpoints
• fix and rename ApiListener (404 error)
• add json response for 4xx and 5xx response
• add info in api docs organization -> alias, packge -> pacakgeId
• check all IsGranted annotations from web controllers and add it to rest controllers ⚠️
• add info to docs about members permission (from Implement members permissions #128) and add link in invite form to this docs
