3.0.0-beta3

• PHP 8.0 or 8.1 are now required. PHP 7.x is no longer supported.
• As part of a modernization effort, we are rewriting the APIs. As we rewrite them, we are dropping all output formats except for json. In this release, the following APIs have been rewritten:
  • GetSearchResults
  • GetServiceBodies
  • GetFormats
  • GetFieldKeys
  • GetFieldValues
  • GetChanges
  • GetServerInfo
• Allow NAWS import code to update the world ID of deleted meetings. (This avoids a synchronization problem that would arise if a new meeting is deleted before its NAWS code can be uploaded.)
