+OBS Studio 33+ installation compatibility.

+- Updated the DLL location to the root of the plugin folder in ProgramData (OBS 33+ and future OBS versions).
+- Migrates existing legacy `bin\64bit` installs with an atomic folder swap and rollback on failure.
+- Updated CMake packaging, build checks, and Windows portable OBS installation instructions.
+- No changes to encoder reuse, audio tracks, recording, or hotkeys. OBS 32.x users should stay on v0.3.2.

 To remove EB Recorder, close OBS and run `UNINSTALL.cmd` from the extracted release package.
 
-### Portable OBS installation
-
-`INSTALL.cmd` is intended for regular and Steam installations. If OBS is running in portable mode, install EB Recorder manually into the portable OBS folder.
-
-From the extracted EB Recorder release package:
-
-1. Copy `eb-recorder\bin\64bit\eb-recorder.dll` to:
-
-```text
-<OBS Portable>\obs-plugins\64bit\eb-recorder.dll

-
-2. Create this folder if it does not already exist:
-
-```text
-<OBS Portable>\data\obs-plugins\eb-recorder\locale\
-```
-
-3. Copy `en-US.ini` and `ru-RU.ini` from `eb-recorder\data\locale\` into that `locale` folder.
-4. Start the portable OBS build and open **Tools -> EB Recorder**.
+### Portable OBS installation (OBS 33+)
 
-The resulting portable layout should look like this:
+For a portable OBS 33+ installation, copy the extracted release folder `eb-recorder` to `<OBS Portable>\plugins\`. The result must be:

-For portable installations, removal is also manual: close OBS and delete the EB Recorder DLL and its `data\obs-plugins\eb-recorder` folder.
+The normal `INSTALL.cmd` targets ProgramData (not portable OBS). Removal in portable mode is manual: close OBS, then delete the `<OBS Portable>\plugins\eb-recorder` directory.

 Установщик не зависит от папки, в которой установлен OBS, поэтому обычную или Steam-версию OBS можно держать на любом диске.
 
 Установщик не создаёт записей в реестре, служб, задач планировщика и не меняет PATH.
 
 Для удаления закройте OBS и запустите `UNINSTALL.cmd` из распакованного release-архива.

-`INSTALL.cmd` рассчитан на обычную и Steam-установку OBS. Если OBS работает в portable-режиме, EB Recorder нужно установить вручную в папку portable OBS.
-

-
-1. Скопируйте `eb-recorder\bin\64bit\eb-recorder.dll` сюда:
-
-```text
-<OBS Portable>\obs-plugins\64bit\eb-recorder.dll
-```
-
-2. Создайте эту папку, если её ещё нет:

 ```
 
-Для portable-установки удаление тоже выполняется вручную. Закройте OBS, удалите `eb-recorder.dll` и папку `data\obs-plugins\eb-recorder`.
+Обычный `INSTALL.cmd` устанавливает плагин в ProgramData, а не в portable OBS. Для удаления из portable OBS закройте программу и удалите папку `<OBS Portable>\plugins\eb-recorder`.

+# EB Recorder 0.3.3 — OBS Studio 33+ plugin installation
+
+## Changes
+- Updated the Windows release package to the official OBS Studio 33+ third-party plugin layout:
+  - `eb-recorder/eb-recorder.dll`
+  - `eb-recorder/data/locale/en-US.ini`
+  - `eb-recorder/data/locale/ru-RU.ini`
+- Updated the installer to replace older `bin/64bit` installations using its existing staging, validation and rollback strategy. An existing plugin configuration is not changed.
+- Updated CMake packaging, Windows build output validation, English and Russian documentation, and portable OBS instructions.
+- Kept existing Enhanced Broadcasting encoder reuse, Live/VOD audio, Matroska recording, and hotkeys unchanged.
+
+## Compatibility
+- **Target:** OBS Studio 33.x and newer, Windows x64.
+- **OBS 32.x:** continue using EB Recorder v0.3.2; this release's flat plugin layout is not recognized by OBS 32.
+- The build stays pinned to the proven OBS 32.2.2 SDK baseline because the relevant libobs encoder/output APIs and Twitch multitrack encoder names are unchanged in OBS 33.0.0.
+
+## Verification before release
+- [ ] Windows CI builds the v0.3.3 ZIP and SHA256 successfully.
+- [ ] New ZIP has exactly one `eb-recorder.dll` in the plugin root, no legacy copy.
+- [ ] Installer clean install in OBS 33 and upgrade from v0.3.2 do not produce a Legacy badge.
+- [ ] EB Recorder appears under OBS Tools.
+- [ ] Twitch EB recording reuses the top video encoder and Live/VOD audio without additional encoding.
+- [ ] Manual/automatic start-stop and hotkeys work.
+- [ ] Uninstall removes plugin files from ProgramData.
+
+No release should be published until the runtime smoke test is complete.
