 # Changelog
+## 1.5.x
+### 1.5.0: Feature - Time of dateEdit now today
+- Changes that instead of the dateEdit elements being always set to a last day of 2024 it is the current day.
+
+## 1.4.x
+### 1.4.2: Fix links
+- Fixed that changelog was linked to GitLab, not it is to code.boxyfoxy.net
+- Fixed Changelog
+
+### 1.4.1: Fix CI
+- Fixed pipline
+### 1.4.0: New CI
+- Migrated repo from GitLab to my forgejo instance, therefore switching to woodpecker CI
+
+---
+
+## 1.3.x
+### 1.3.4: Fix - Spelling (25.04.01)
+- Fixed misspelling in preview window.
+
+### 1.3.3: Patch - Increased Preview Performance x2 (25.04.01)
+- Reduced preview stutter: Previously, the image was updated twice when changing brightness or contrast. Now, it updates only once, improving performance by 100%.
+- There is still room for improvement. Analysis shows that image processing takes the most time, while displaying in Qt is relatively fast. Reducing the image size impacts performance, so resizing to 50% is a good idea.
+- There is an issue where `QRunner` does not always finish in the correct order when brightness or contrast values are changed rapidly. ATM I do not know how to fix this easly.
+- The "Preview" watermark now displays the brightness and contrast levels of the shown image.
+
+### 1.3.2: Fix - Fixed problem with app folders (25.03.30)
+- Fixed a problem that the app folder path was not generated correctly.
+
+### 1.3.1: Fix - Fixed insert exif not working (25.03.27)
+- Fixed the feature that inserted exif into images without modifying them.
+
+### 1.3.0: Feature - Write Adjustments into EXIF (25.03.24)
+- Changes to contrast and brightness are now recorded in the EXIF comment section (labeled *Scanner* in the program).
+- This allows users to track what adjustments were made to an image.
+
+---
+
+## 1.2.x
+### 1.2.2: Patch - Pyproject file (25.03.23)
+- Fixed `Development Status` Classifier
+- Added <4.0 python version
+
+### 1.2.1: Patch - Changelog file (25.03.23)
+- Patches formation in changelog file.
+
+### 1.2.0: Refactor - Splitting Classes into Separate Files (25.03.23)
+- Refactored `gui.py`, which previously contained almost all the code, into multiple files.
+- Each window's logic is now in its own file, improving code organization.
+- Window layouts remain in `.ui` folder, while their logic is now properly separated.
+
+## 1.1.x
+### 1.1.0: Feature - New Function in Preview Window (25.03.23)
+- Added a new feature to the preview window: **Hold a button to temporarily view the original (unedited) image.** This makes it easier to compare changes.
+- Minor UI adjustments.
+
+---
+
+## 1.0.x (25.03.06)
+### 1.0.1: Fixed spelling
+- Fixes spelling some places
+
+### 1.0.0: Fix version bump
+- Version was not bumped correctly
+
+---
+
+## 0.15.1: Final Polish (25.03.06)
+- Fixed a bug where the GPS field being empty but selected caused issues.
+- EXIF insertion is now canceled if any image in the folder does not end with a number.
+- Minor GUI adjustments for a more polished experience.
+- Disabled preview adjustment controls until an image is loaded to prevent errors.
+
+## 0.15.0: Preview Image Resizing Update (25.02.12)
+- Added the ability to change the preview image size dynamically.
+- Previously, the image was processed and displayed at its original size, causing lag or unresponsiveness when adjusting the slider.
+- Reducing the processed image size should help improve performance.
+- Default preview image size is now **25%**, but users can adjust it between **10% and 100%**.
+
+---
+
+## 0.14.x
+### 0.14.1: Patch changelog (25.02.12)
+- Updated the changelog to include missing entries.
+
+### 0.14.0: Code refactor (by Mr. Finch) (25.02.11)
+- Introduced constants and optimized the code.
+
+## 0.13.x (25.02.11)
+### 0.13.1: Fixed image processing
+- Fixed a bug that made it impossible to process images.
+
+### 0.13.0: Requirements file (by Mr. Finch)
+- Added a requirements file.

 ## 0.12.x
-### 0.12.1: Removed Unnecessary Debug Prints
- Removed leftover debug print statements.
+### 0.12.6: Disabled app restart on Windows (25.02.11)

-### 0.12.0: New Settings Menu & Patches
+### 0.12.5: Fixed EXIF File Generation Bug (25.02.10)

 ## **Overview**

 **OptimaLab35** enhances **OPTIMA35** (**Organizing, Processing, Tweaking Images, and Modifying scanned Analogs from 35mm Film**) by offering a user-friendly graphical interface for efficient image and metadata management.

-It serves as a GUI for the [OPTIMA35 library](https://gitlab.com/CodeByMrFinchum/optima35), providing an intuitive way to interact with the core functionalities.

 ## **Current Status**
-### **Early Development**
-OptimaLab35 is actively developed using **PySide6** and **Qt**, providing a modern interface for **OPTIMA35**.
-
-The program is still in its early stages, and features may change drastically over time. Some features might be added but later removed if they don't prove useful. Expect significant changes to the UI and functionality between updates.
-
-For the most accurate and detailed update information, please refer to the [**CHANGELOG**](https://gitlab.com/CodeByMrFinchum/OptimaLab35/-/blob/main/CHANGELOG.md) as the readme might lack behind.
+The program has reached a stable release. All functions have been tested, and there should be *no* bugs.
+While there is always room for additional features and optimizations, the core functionality is complete and reliable.
