    ### 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_name>/addon.cfg files (PR #5038).
      • Full add-on packs are now stored as data/<addon_name>/full_pack_<version_md5>.gz files instead of data/<addon_name>.
      • Hash indexes of full add-on packs are stored as data/<addon_name>/full_pack_<version_md5>.hash.gz.
    • Implemented support for incremental add-on downloads and uploads (issue #5046, PR #5038):
      • Incremental update packs are stored as data/<addon_name>/<version_from_to_md5>.gzfiles.
      • 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
    • Updated translations: British English, Czech, French, Japanese, Polish, Portuguese (Brazil)
    • The font-handling now checks which glyphs are in each font, instead of using a list hardcoded in WML.
      • A bug in the removed code treated the first font containing U+4E00 as having the whole CJK Unified Ideographs block.
      • Fixes a bug where many Chinese characters were invisible if DroidSansJapanese was loaded before DroidSansFallbackFull (issue #5194).
    • Changing the language immediately updates the order of the fonts, instead of waiting for the next restart (issue #5194). ### Lua API
    • Implement new GUI2 widget userdata for working with custom dialogs.
    • Renamed wesnoth.show_dialog to gui.show_dialog. The preshow and postshow now take a single parameter - a widget userdata.
    • All other dialog functions (such as wesnoth.get_dialog_value and wesnoth.set_dialog_value) are now deprecated. ### 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. ### Packaging

  • v1.15.3 Changes

    ### AI

    • Merge Experimental AI candidate actions (CAs) into default AI
      • CAs merged: retreat injured, spread poison, place healers, move to any enemy
      • CAs not merged: grab villages and village hunt, as the respective default AI CAs are better as general purpose CAs. Also not merged was castle switch, which can cause undesired behavior in singleplayer scenarios, and recruit rushers, which is too different from default recruiting (would change balance too much) and because it can currently not deal with multiple leaders and all the recruitment aspects. An option to use this alternative recruiting will be provided in the future.
      • Previous default AI CA removed: retreat phase
      • The previous default CA is still available by using [ai]ai_algorithm=ai_default_rca_1_14 or by selecting "1.14 Default AI" in the multiplayer computer player selection menu
      • The Experimental AI is now only available in debug mode (in MP) as it is mostly identical to the new default AI

This file should contain one of the following values based on where the package is for: Default, Steam, SourceForge, Flatpak, macOS App Store, Linux repository, iOS, Android, BSD repository ### Miscellaneous and bug fixes
