Bridge Ultra v1.1.0

Bridge Ultra v1.1.0

First public release. Brings a rewritten native installer GUI on top of
the v1.0 bridging runtime, plus a sweep of stability fixes for plugin
GUI, project save, and sub-process lifecycle.

第一次公开发布。在 v1.0 桥接运行时的基础上重写了原生安装器 GUI，并修了
一批插件 GUI、工程保存、子进程生命周期相关的稳定性问题。

Install

Download BridgeUltra-Setup-1.1.0.exe below, double-click, accept the
UAC prompt. The installer copies three binaries to
%ProgramFiles%\Bridge Ultra\ and registers an Apps & Features entry
for clean uninstall.

下载下方 BridgeUltra-Setup-1.1.0.exe，双击运行，授予管理员权限。
安装器会把三个二进制安装到 %ProgramFiles%\Bridge Ultra\ 并注册到
"应用和功能"以便干净卸载。

What's new

Installer

• New native GUI — Win32 + Direct2D + DirectWrite, bilingual zh/en,
  system theme aware (light / dark / high-contrast), keyboard-traversable,
  fixed 960×640 design.
• Robust overwrite install — uses MoveFileEx rename-aside +
  delete-on-reboot so the installer can replace BridgeUltra.exe even
  while a previous instance is running. Also kills any running
  BridgeUltra.exe instance first via TerminateProcess before copying
  the new binary in.
• Theme detection under elevation — the installer reads
  AppsUseLightTheme from the launching user's HKEY_USERS hive
  (resolved via the active console session SID) rather than
  HKEY_CURRENT_USER, so the elevated installer no longer paints dark
  over a user's light theme.

GUI stability

• Cross-process plugin window survives DAW panel teardown —
  introduced a JBridge-style stash-parent pattern (off-screen WS_VISIBLE
  WS_POPUP top-level window). When the DAW's plugin panel is destroyed
  on close, our 64-bit container reparents to the stash window instead
  of being recursively destroyed. Re-open reparents back, the plugin's
  32-bit child rides along, no effEditClose(value=1) round-trip is
  needed. Fixes "GUI doesn't appear on second open" for Cakewalk-style
  skin engines (Delay R3, Native Reverb Plus, Surround R3).
• Win11 minimise → restore — SWP_FRAMECHANGED re-broadcast on
  SIZE_RESTORED forces DWM to re-apply our custom NCCALCSIZE rule,
  fixing the "transparent / blank window after minimise" symptom on
  Win11 22H2+.

IPC / lifecycle

• Studio One save latency — effSetProgram / effGetProgram
  fast-fail on dead IPC instead of burning a 5 s timeout per opcode.
  Per-plugin save loss drops from up to 25 s to under 600 ms when the
  child sub-process has gone unresponsive.
• host32 zombie processes — control_pipe_server::ioLoop now
  clears its running_ flag on every exit path (was: only on
  K_SHUTDOWN). The 32-bit sub-process now exits cleanly when the DAW
  unloads the plugin, instead of lingering until the DAW process dies.

Known issues

• Extremely rapid double-click cycles on a plugin slot can occasionally
  leave the editor blank in some hosts. Mitigations cover the common
  patterns; the v2.0 roadmap is to adopt the carla-bridge-win32 full
  GUI shell model for complete robustness.
• DRM / iLok-protected plugins inspect the parent process tree and may
  reject loading under BridgeUltraHost32.exe. No workaround planned.

Compatibility

• Windows 10 1809+ / Windows 11 (64-bit only)
• 64-bit DAW host (Studio One, Cubase, Reaper, FL Studio, Ableton Live,
  Bitwig …) targeting VST2
