Changelog — FulDC++

Play releases while downloading — start watching before a download finishes, with seek-ahead buffering, automatic subtitle prefetch, resume support and buffer progress shown on the tab.
Multi-part releases now download in the right order, so the first volume is ready first; file priorities are restored when playback stops.
Settings backup & restore — back up your configuration and restore it later from a new Backup settings page.
Fixed the right-click menu dying in chats that had shown an emoticon.
Fixed a handle leak from chat images that could blank the toolbar and kill right-click menus during long sessions.

Automatic away mode: set away when the computer is locked, when a full-screen application is running, when the main window is minimized, or after inactivity — each with its own optional away message (Settings > General > Away).
Chat modernization: multiple emoticon packs with animated GIF emoticons, BBCode rendering for incoming messages, and an optional chat formatting toolbar.
Favorite Hubs window overhaul: filter bar, status bar, last-connected info and drag-drop reordering; connect to a whole favorite group at once; Window menu expanded.
Fixed the manual update check silently doing nothing in some situations.

New /fuldc chat command; old AirDC++ command aliases removed.
Hub chat internals reworked (nick insertion, command handling, safer buffers).
Crash reports are now symbolicated: releases ship a compact symbol file, so bug reports show real function names.
About dialog now shows the latest available version from fuldcpp.net.
External IP check switched to a secure HTTPS service.
Help-menu links now point to fuldcpp.net.

In-client automatic updates now live via fuldcpp.net (signed, self-installing).
New FulDC++ website and download portal.
Removed all remaining connections to the upstream airdcpp.net project (update, GeoIP fallback, language, crash and homepage links now point at FulDC++).

In-client automatic updates, delivered signed from this site.
Runs fully side-by-side with AirDC++ (separate instance and profile folders, with one-time profile import).
New orbs icon and dark splash; About dialog reworked.
GUI modernization wave: inline chat find bar, resizable dialogs, TaskDialog prompts, recent-hubs dropdown, quick-connect sparklines.
Native DCAPI plugin system (DCAPI v8).
Chat triggers with regex capture groups, away-only mode and import/export.
Group users by type (Ops / Bots / Users) with live counts.
Auto-recovery / crash supervisor with freeze watchdog.
Self-updating GeoIP with dedicated settings page.
Protocol robustness: ADC and NMDC gap fixes, UDP hardening, keyprint-mismatch re-pin dialog.
