anchor.diff:  Ensure all configurations are up to date, especially the elasticsearch schema then reindex the data.
   
   *Further bug with recurrences.* In caldav if an override was deleted from the event it was not deleted from the system.
  +
  +*Scheduling bug fix* Trying to invite a new bedework user to a meeting could result in an NPE
  +
  +*Category bug fix* For personal events, multiple new categories in an event were not getting indexed correctly - only the last one. They were created correctly in the database - a reindex will fix any missing categories.
  +
  +This dos not affect public events.
   
   *New quickstart deployment method.* Opting for no sources in the install script will now mean that the required components are downloaded directly from maven central. Currently git is required for part of the install but maven will not be required in this case.
   
  
positive.code: === Release Notes
  
  ==== Dev:
  **Admonition Block:**
  [NOTE]
  ====
  A significant - but long standing - bug was discovered. Override attachments were not being stored as the table and schema entries were missing. Updating will require adding the table to the database (or recreating the data from the XML dump).
  
  Additionally - ensure the elasticsearch schema is up to date
  (wildfly/standalone/configuration/bedework/elasticsearch) and reindex
  after the system is updated.
  
  
negative.code:         Referenced entities - e.g. locations, were not getting restored
            in some cases - see https://github.com/Bedework/bw-calendar-engine/commit/58df20469660d4fe4f2fcef15992147979e3717c#diff-4fb4cfb2524a3a8ea92fc90a4fc31b60
