@@ -1,3 +1,127 @@
+# 1.2.2
+- **You can now voice your subtitle files!** Simply add `.srt`, `.ass` or `.vtt` files to generate timed audio. Alternatively, add a text file with timestamps in `HH:MM:SS` or `HH:MM:SS,ms` format to generate audio that matches the timestamps. See [here](https://github.com/denizsafak/abogen?tab=readme-ov-file#about-timestamp-based-text-files) for detailed instructions.
+    - New option: **"Use silent gaps between subtitles"**: Prevents unnecessary audio speed-up by letting speech continue into the silent gaps between subtitles.
+    - New option: **"Subtitle speed adjustment method"**: Choose how to speed up audio when needed:
+        - **TTS Regeneration (better quality):** Re-generates the audio at a faster speed for more natural sound.
+        - **FFmpeg Time-stretch (better speed):** Quickly speeds up the generated audio.
+- Added support for embedding cover images in M4B files. Abogen now automatically extracts cover images from EPUB and PDF files. You can also manually specify a cover image using the `<<METADATA_COVER_PATH:path>>` tag in your text file. (To prevent MPV from showing the cover image, you can add `audio-display=no` to your MPV config file.)
+- Fixed `[WinError 1114] A dynamic link library (DLL) initialization routine failed` error on Windows, pre-loading PyTorch DLLs before initializing PyQt6 to avoid DLL initialization errors, mentioned in #98 by @ephr0n.

+- Better sleep state handling for Linux.
+- The app window now tries to fit the screen if its height would exceed the available display area.
+- Fixed issue where the app would not restart properly on Windows.
+- Fixed last sentence/subtitle entry timing in generated subtitles, the end time of the final subtitle entry now correctly matches the end of the audio chunk, preventing zero or invalid timings at the end.

+## `Queue Mode`
+<img title="Abogen queue mode" src='https://raw.githubusercontent.com/denizsafak/abogen/refs/heads/main/demo/queue.png'>
+
+Abogen supports **queue mode**, allowing you to add multiple files to a processing queue. This is useful if you want to convert several files in one batch.
+
+- You can add text files (`.txt`) directly using the **Add files** button in the Queue Manager. To add PDF, EPUB, or markdown files, use the input box in the main window and click the **Add to Queue** button.
+- Each file in the queue keeps the configuration settings that were active when it was added. Changing the main window configuration afterward does **not** affect files already in the queue.
+- You can view each file's configuration by hovering over them.
+
+Abogen will process each item in the queue automatically, saving outputs as configured.

+## `About Metadata Tags`
+Similar to chapter markers, it is possible to add metadata tags for `M4B` files. This is useful for audiobook players that support metadata, allowing you to add information like title, author, year, etc. Abogen automatically adds these tags when you process ePUB, PDF or markdown files, but you can also add them manually to your text files. Add metadata tags **at the beginning of your text file** like this:
+```
+<<METADATA_TITLE:Title>>
+<<METADATA_ARTIST:Author>>
+<<METADATA_ALBUM:Album Title>>
+<<METADATA_YEAR:Year>>
+<<METADATA_ALBUM_ARTIST:Album Artist>>
+<<METADATA_COMPOSER:Narrator>>
+<<METADATA_GENRE:Audiobook>>
+<<METADATA_COVER_PATH:path/to/cover.jpg>>
+```
+> Note: `METADATA_COVER_PATH` is used to embed a cover image into the generated M4B file. Abogen automatically extracts the cover from EPUB and PDF files and adds this tag for you.
+
+## `About Timestamp-based Text Files`
+Similar to converting subtitle files to audio, Abogen can automatically detect text files that contain timestamps in `HH:MM:SS` or `HH:MM:SS,ms` format. When timestamps are found inside your text file, Abogen will ask if you want to use them for audio timing. This is useful for creating timed narrations, scripts, or transcripts where you need exact control over when each segment is spoken.
+
+Format your text file like this:
+```
+00:00:00
+This is the first segment of text.
+
+00:00:15
+This is the second segment, starting at 15 seconds.
+
+00:00:45
+And this is the third segment, starting at 45 seconds.
+```
+
+**Important notes:**
+- Timestamps must be in `HH:MM:SS` or `HH:MM:SS,ms` format (e.g., `00:05:30` for 5 minutes 30 seconds, or `00:05:30,500` for 5 minutes 30.5 seconds)
+- Milliseconds are optional and provide precision up to 1/1000th of a second
+- Text before the first timestamp (if any) will automatically start at `00:00:00`
+- When using timestamps, the subtitle generation mode setting is ignored

+</b></summary>
+
+> The name **"abogen"** comes from a shortened form of **"audiobook generator"**, which is the purpose of this project.  
+>
+> After releasing the project, I learned from [community feedback](https://news.ycombinator.com/item?id=44853064#44857237) that the prefix *"abo"* can unfortunately be understood as an ethnic slur in certain regions (particularly Australia and New Zealand). This was something I was not aware of when naming the project, as English is not my first language.  
+>
+> I want to make it clear that the name was chosen only for its technical meaning, with **no offensive intent**. I’m grateful to those who kindly pointed this out, as it helps ensure the project remains respectful and welcoming to everyone.

+</b></summary>
+
+> This message means PyTorch could not use your GPU and has fallen back to the CPU. On Windows, Abogen only supports NVIDIA GPUs with CUDA. AMD GPUs are not supported on Windows (they are only supported on Linux with ROCm). Abogen will still work on the CPU, but processing will be slower compared to a supported GPU.
+>
+> If you have a compatible NVIDIA GPU on Windows and still see this warning:
+> Open your terminal in the Abogen folder (the folder that contains `python_embedded`) and type:
+> ```bash
+> python_embedded\python.exe -m pip install --force-reinstall torch==2.8.0+cu128 torchvision==0.23.0+cu128 torchaudio==2.8.0 --index-url https://download.pytorch.org/whl/cu128
+> ```
+>
+> If this does not resolve the issue and you are using an older NVIDIA GPU that does not support CUDA 12.8, you can try installing an older version of PyTorch that supports your GPU. For example, for CUDA 12.6, run:
+> ```bash
+> python_embedded\python.exe -m pip install --force-reinstall torch==2.8.0+cu126 torchvision==0.23.0+cu126 torchaudio==2.8.0 --index-url https://download.pytorch.org/whl/cu126
+> ```
+> 
+> If you have an AMD GPU, you need to use Linux and follow the Linux/ROCm [instructions](#linux). If you want to keep running on CPU, no action is required, but performance will just be reduced. See [#32](https://github.com/denizsafak/abogen/issues/32) for more details.
