 Finally, Optix is a reference to an old Remote Access Trojan of the same name from the early 2000s, and the program's logo is also a direct reference to it. The connection is a tribute, which is a recurring theme in many of my projects.

 ## Changelogs
 
+### 1.1.0 (Sept 2025)
+
+* **Folder Tree View Added to File Manager:** The browsed folder tree is now optionally available in the file manager (default: enabled).
+* **File Upload Feedback Added:** When a file is uploaded, all file manager windows are notified if the new file matches the current directory (reactive update).
+* **Significant Protocol Improvements:** While not directly visible in the compiled version, the underlying code has been greatly enhanced. Optix command dispatching is now handled generically, and command/response serialization and deserialization are partially automated using the power of Delphi RTTI for most basic object and property types. This considerably reduces the time required to implement new commands and responses, minimizes potential implementation errors, and makes the project much easier to expand.

 ### 1.0.0 (Sept 2025)
 
 * **Column sorting:** Improved data navigation with sortable columns.
