+## Version 1.4.0
+
+The 1.4.0 release of MCUboot primarily adds support for multi-image
+booting. With this release, MCUboot can manage two images that can be
+updated independently. With this, it also supports additions to the
+TLV that allow these dependencies to be specified.
+
+Multi-image support adds backward-incompatible changes to the format
+of the images: specifically adding support for protected TLV entries.
+If multiple images and dependencies are not used, the images will be
+compatible with previous releases of MCUboot.
+
+### About this release
