CHANGELOG.md

@@ -1,3 +1,71 @@
+# 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.
+- Potential fix for `CUDA GPU is not available` issue, by ensuring PyTorch is installed correctly with CUDA support on Windows using the installer script.
+- Improvements in code and documentation.
+
+# 1.2.1
+- Upgraded Abogen's interface from PyQt5 to PyQt6 for better compatibility and long-term support.
+- Added tooltip indicators in queue manager to display book handler options (`Save chapters separately` and `Merge chapters at the end`) for queued items.
+- Added `Open processed file` and `Open input file` options for items in the queue manager, instead of just `Open file` option.
+- Added loading gif animation to book handler window.
+- Fixed light theme slider colors in voice mixer for better visibility (for non-Windows users).
+- Fixed subtitle word-count splitting logic for more accurate segmentation.
+- Improvements in code and documentation.
+
+# 1.2.0
+- Added `Line` option to subtitle generation modes, allowing subtitles to be generated based on line breaks in the text, by @mleg in #94.
+- Added a loading indicator to the book handler window for better user experience during book preprocessing.
+- Fixed `cannot access local variable 'is_narrow'` error when subtitle format `SRT` was selected, mentioned by @Kinasa0096 in #88.
+- Fixed folder and filename sanitization to properly handle OS-specific illegal characters (Windows, Linux, macOS), ensuring compatibility across all platforms when creating chapter folders and files.
+- Fixed `/` and `\` path display by normalizing paths.
+- Fixed book reprocessing issue where books were being processed every time the chapters window was opened, improving performance when reopening the same book.
+- Fixed taskbar icon not appearing correctly in Windows.
+- Fixed “Go to folder” button not opening the chapter output directory when only separate chapters were generated.
+- Improvements in code and documentation.
+
+# 1.1.9
+- Fixed the issue where spaces were deleted before punctuation marks while generating subtitles.
+- Fixed markdown TOC generation breaks when "Replace single newlines" is enabled.
+- Improvements in code and documentation.
+
+# 1.1.8
+- Added `.md` (Markdown) file extension support by @brianxiadong in PR #75
+- Added new option `Configure silence between chapters` that lets you configure the silence between chapters, mentioned by @lfperez1982 in #79
+- Better indicators and options while displaying and managing the input and processing files.
+- Improved the markdown logic to better handle various markdown structures and cases.
+- Fixed subtitle splitting before commas by combining punctuation with preceding words.
+- Fixed save options not working correctly in queue mode, mentioned by @jborza in #78
+- Fixed `No Qt platform plugin could be initialized` error, mentioned by @sunrainxyz in #59
+- Fixed ordered list numbers not being included in EPUB content conversion. The numbers are now properly included in the converted content, mentioned by @jefro108 in #47
+- Potentially fixed subtitle generation stucks at 9:59:59, mentioned by @bolaykim in #73
+- Improvements in code and documentation.
+
+# 1.1.7
+- Added MPS GPU acceleration support for Silicon Mac, mentioned in https://github.com/denizsafak/abogen/issues/32#issuecomment-3155902040 by @jefro108. **Please read the [Mac](https://github.com/denizsafak/abogen?tab=readme-ov-file#mac) section in the documentation again, as it requires additional configuration.**
+- Added word-by-word karaoke highlighting feature by @robmckinnon in PR #65
+- Fixed sleep inhibition error occurring on some Linux systems that do not use systemd, mentioned in #67 by @hendrack

+## `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

+<a name="about-abogen">About the name "abogen"</a>
+</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.

+<a name="cuda-warning">How to fix "CUDA GPU is not available. Using CPU" warning?</a>
+</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.
