# v0.2.7

## Refactoring

- Extracted `ChatMessageManager` from `MainWindow` — message storage, formatting, and mutation logic now in a dedicated class, reducing MainWindow complexity
- Split `ChatRenderer.cs` (8 classes, 548 lines) into 7 individual files: `ChatSegment`, `ChatLine`, `ChatListSource`, `ChannelListSource`, `UserListSource`, `ChatColors`, `ColorHelper`, `RenderHelpers`
- Extracted `ConnectionManager` from `AppOrchestrator` — connection lifecycle, authentication, SignalR event wiring, and channel tracking now in a dedicated service
- Extracted `AvatarHelper` — deduplicated avatar upload logic previously duplicated in `/avatar` command and profile edit dialog
- Consolidated `ProfileEditDialog.ParseHexToTrueColor` into shared `ColorHelper.ParseHexToColor`
- Extracted `UserSession` — session state (`Username`, `Status`, `StatusMessage`) now in a dedicated class instead of scattered fields
- Replaced 21 inline command handler lambdas with named `HandleCmd*` methods for improved readability
- Extracted shared `CleanupConnectionAsync` to deduplicate disconnect/logout cleanup logic
- Reorganized flat `UI/` folder (19 files) into subfolders: `Chat/`, `Dialogs/`, `ListSources/`, `Helpers/` with matching namespaces
- Moved `AsyncRunner` from project root to `Services/` with updated namespace
- Renamed `ColorHelper` → `HexColorHelper` to avoid namespace collision with Terminal.Gui's `ColorHelper` NuGet dependency
- Moved `hue_icon.ico` to `Client/Assets/`, removed duplicate from Server (Server now references shared icon via relative path)

## Bug Fixes

- Fix user list empty on initial connect — `FetchAndUpdateOnlineUsers` was called before `InvokeUI` set the current channel, causing an early return

## Infrastructure

- Switch Terminal.Gui from local fork submodule back to NuGet package (`2.0.0-develop.5039`) — transparent color PR merged upstream
- Remove Terminal.Gui submodule, `.gitmodules`, and root `nuget.config` workaround
- Remove `rm -f` submodule nuget.config steps and `submodules: recursive` from all 3 CI workflows (ci, docs, release)
- Remove `--exclude src/Terminal.Gui/` from format check
