 # Changelog
 
+## v2.7.2
+
+This release updates to [Buildroot
+2020.05.1](http://lists.busybox.net/pipermail/buildroot/2020-July/287824.html)
+and OTP 23.0.3 which are both bug fix releases.
+
+* Updated dependencies
+  * [nerves_system_br: bump to v1.12.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.12.4)
+  * [Erlang/OTP 23.0.3](https://erlang.org/download/OTP-23.0.3.README)
+  * [nerves_heart v0.3.0](https://github.com/nerves-project/nerves_heart/releases/tag/v0.3.0)
+
+* New features
+  * The `/data` directory now exists for storing application-specific data. It
+    is currently a symlink to `/root`. Using `/data` will eventually be
+    encouraged over `/root` even though currently there is no advantage. This
+    change makes it possible to start migrating paths in applications and
+    libraries.
+
+* Fixes
+  * Fixed old references to the `-Os` compiler flag. All C/C++ code will default
+    to using `-O2` now.
+
