+# 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.
+
 # v1.1.0
 - Added queue system for processing multiple items, allowing users to add multiple files and process them in a queue, mentioned by @jborza in #30 (Special thanks to @jborza for implementing this feature in PR #35)
 - Added a feature that allows selecting multiple items in book handler (in right click menu) by @jborza in #31, that fixes #28
