Add-ons client

• Implemented support for incremental add-on downloads and uploads (issue #5046, PR #5038).
  

Add-ons server

• The server configuration no longer contains the add-ons list/metadata (PR #5038):
  
  
  • Metadata is now stored in individual `data//addon.cfg` files (PR #5038).
    
  • Full add-on packs are now stored as `data//full_pack_.gz` files instead of `data/`.
    
  • Hash indexes of full add-on packs are stored as `data//full_pack_.hash.gz`.
    
  
  

• Implemented support for incremental add-on downloads and uploads (issue #5046, PR #5038):
  
  
  • Incremental update packs are stored as `data//.gz`files.
    
  • Incremental update packs are allowed to be sent by clients in `[upload]` and may be asked from the server in `[request_campaign]`.
    
  • The server can generate an incremental update pack while servicing `[upload]` if the client doesn't send one (e.g. old clients).
    
  
  

• Previous versions of add-ons are stored on the server for a limited amount of time alongside update packs for older versions (30 days by default) (PR #5038).
  

Language and i18n

  • Fixes a bug where many Chinese characters were invisible if DroidSansJapanese was loaded before DroidSansFallbackFull (issue #5194).

Lua API

• Implement new GUI2 widget userdata for working with custom dialogs.

Multiplayer

• Delay Advancements modification:
  
  
  • The Delay Advancements modification allows changing how advancements are handled. With this enabled, units that previously would have advanced on another player's turn will instead not advance until it is again their side's turn. The benefit of this is that units will also not pick an advancement at random if they have multiple.
