 ## [Unreleased]
 
+## [4.0.5] - 2024-06-15
+
 ### Added
 - Possibility to navigate Artemis just with the keyboard [#50](https://github.com/AresValley/Artemis/issues/50)
+- **Windows:** automatic updates have been implemented. When a software update is available, Artemis will download the new version and install the updates automatically 
+- Multiple sigID databases can be conserved. In the case of autoload, the latest local version will be loaded
+- Added creation date and DB version in DB manager window
 
 ### Changed
 - Improved readability of labels for filter ranges for frequency, bandwidth, and ACF
+- Improved Update manager and Downloader functionalities
+- OS dependent temporary folders are now used for database download and artemis updates
+- The logic for searching the last sigID database has changed, now the discriminant is no longer the folder name but is reported as a signature in the database itself (-1 in the editable field, see documentation)
+- Old sigID databases are not deleted anymore when a new version is downloaded. This is to avoid removing databases with user changes or additions
 
 ### Fixed
 - Added a database load check to avoid (non critical) exceptions when applying filters without having loaded a database.
+- Fixed a potential issue involing the forcibly closure of downloader window but the downloader instance keeps running
+- With the new logic in the latest sigID database search, manually imported sigID databases are officially recognized as proper ones
