+## DataLab Version 0.16.0 ##
+
+💥 New features and enhancements:
+
+* Major user interface overhaul:
+  * The menu bar and toolbars have been reorganized to make the application more
+    intuitive and easier to use
+  * Operations and processing features have been regrouped in submenus
+  * All visualization-related actions are now grouped in the plot view vertical toolbar
+  * Clarified the "Annotations" management (new buttons, toolbar action, ...)
+
+* New validation process for signal and image features:
+  * Before this release, DataLab's validation process was exclusively done from the
+    programmer's point of view, by writing unit tests and integration tests, thus
+    ensuring that the code was working as expected (i.e. that no exception was raised
+    and that the behavior was correct)
+  * With this release, a new validation process has been introduced, from the user's
+    point of view, by adding new validation functions (marked with the
+    `@pytest.mark.validation` decorator) in the test suite
+  * A new "Validation" section in the documentation explains how validation is done
+    and contains a list of all validation functions with the statistics of the
+    validation process (generated from the test suite)
+  * The validation process is a work in progress and will be improved in future versions
+
+* "Properties" group box:
+  * Added "Scales" tab, to show and set the plot scales:
+    * X, Y for signals
+    * X, Y, Z (LUT range) for images
+
+* View options:
+  * New "Show first only" option in the "View" menu, to show only the first curve
+    (or image) when multiple curves (or images) are displayed in the plot view
+  * New (movable) label for FWHM computations, additional to the existing segment annotation
+
+* I/O features:
+  * Added support for reading and writing .MAT files (MATLAB format)
+  * Create a new group when opening a file containing multiple signals or images (e.g. CSV file with multiple curves)
+
+* Add support for binary images
+* Signal ROI extraction: added new dialog box to manually edit the ROI lower and upper bounds after defining the ROI graphically
+

+🛠️ Bug fixes:
+
+* Fixed a performance issue due to an unnecessary refresh of the plot view when adding a new signal or image
+* Fixed [Issue #77](https://github.com/DataLab-Platform/DataLab/issues/77) - Intensity profiles: unable to accept dialog the second time
+* Fixed [Issue #75](https://github.com/DataLab-Platform/DataLab/issues/75) - View in a new window: curve anti-aliasing is not enabled by default
