+# 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
+- Improvements in code and documentation.
+
+# 1.1.6
+- Improved EPUB chapter detection: Now reliably detects chapters from NAV HTML (TOC) files, even in non-standard EPUBs, fixes the issue mentioned by @jefro108 in #33
+- Fixed SRT subtitle numbering issue, mentioned by @page-muncher in #41
+- Fixed missing chapter contents issue in some EPUB files.
+- Windows installer script now prompts the user to install the CUDA version of PyTorch even if no NVIDIA GPU is detected.
+- Abogen now includes Mandarin Chinese (misaki[zh]) by default; manual installation is no longer required.
+
+# 1.1.5
+- Changed the temporary directory path to user's cache directory, which is more appropriate for storing cache files and avoids issues with unintended cleanup.
+- Fixed the isssue where extra metadata information was not being saved to M4B files when they have no chapters, ensuring that all metadata is correctly written to the output file.
+- Fixed sleep prevention process not ending if program exited using Ctrl+C or kill.
+- Improved automatic filename suffixing to better prevent overwriting files with the same name, even if they have different extensions.
+- Improvements in code and documentation.
+
+# 1.1.4
+- Fixed extra metadata information not being saved to M4B files, ensuring that all metadata is correctly written to the output file.
+- Reformatted the code using Black for better readability and consistency.
+
+# 1.1.3
+- `M4B (with chapters)` generation is faster now, as it directly generates `m4b` files instead of converting from `wav`, which significantly reduces processing time, fixes the issue mentioned by @Milor123 in #39 
+- 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.
+
+# v1.1.2
+- Now you can play the audio files while they are processing.
+- Audio and subtitle files are now written directly to disk during generation, which significantly reduces memory usage.
+- Added a better logic for detecting chapters from the epub, mentioned by @jefro108 in #33
+- Added a new option: `Reset to default settings`, allowing users to reset all settings to their default values.
+- Added a new option: `Disable Kokoro's internet access`. This lets you prevent Kokoro from downloading models or voices from HuggingFace Hub, which can help avoid long waiting times if your computer is offline.
+- HuggingFace Hub telemetry is now disabled by default for improved privacy. (HuggingFace Hub is used by Kokoro to download its models)
+- cPotential fix for #37 and #38, where the program was becoming slow while processing large files.
+- Fixed `Open folder` and `Open file` buttons in the queue manager GUI.
+- Improvements in code structure.
+
 # v1.1.1
 - Fixed adding wrong file in queue for EPUB and PDF files, ensuring the correct file is added to the queue.
 - Reformatted the code using Black.

+
+> 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.

+
+> Abogen needs "pip", because Kokoro uses pip to download voice models from HuggingFace Hub. If you want to use "uv" instead of "pip", you can use the following command to run Abogen:
+>
+> ```bash
+> uvx --with pip abogen

+> - From the settings menu, go to `Open configuration directory` and delete the directory.
+> - From the settings menu, go to `Open cache directory` and delete the directory.
+> - If you installed Abogen using pip, type:
+>```bash
+>pip uninstall abogen # uninstalls abogen
+>pip cache purge # removes pip cache
+>```
+> - If you installed Abogen using the Windows installer (WINDOWS_INSTALL.bat), just remove the folder that contains Abogen. It installs everything inside `python_embedded` folder, no other directories are created.
+> - If you installed espeak-ng, you need to remove it separately.
