Appropriate Action

• Migrated from Travis CI to Github Actions. (#6) @Jack12816

Custom Crack

• Improved the MAM result manipulation to directly change the XML elements
  instead of using the XMPP parsed variant, this will keep user defined
  non-XMPP custom XML elements (stanzas) in place

Many Match

• Added a testing chat client to debug bugs and the implementation easily
• Corrected the MAM result matching and made it more robust to varying element
  order

Composed Code

• Do not remove the meta.user data from a MUC packet in order to not interfere
  with other modules (eg. mod_mam2sidekiq)

Fancy Funeral

• Corrected a module boot up configuration bug, we just fall back to the
  original mod_read_markers
  solution

Rapid Replacement

• Initial release of the ejabberd-unread (mod_unread) module
• Implementation of the initial concept (IQ handler, database (SQL) backend)
• Added a simple test suite to verify the functional state of the module
