+# 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.
+- 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)
+- Potential 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
