+title: Pebble SDK 4.0-dp2 - Changelog
+date: 2016-06-22
+---
+
+This is a developer preview release of SDK 4.0. No firmware is provided.
+
+### Changes to Firmware
+
+* Fixed a bug causing ``APP_GLANCE_SLICE_NO_EXPIRATION`` to mean "expire immediately"
+  rather than the intended "expire never".
+* Fixed a bug causing empty app glances (i.e. attempts to remove all glances) to be
+  ignored.
+
+### Changes to SDK
+
+* None.
+
+### Known Issues
+
+* The `UnobstructedAreaHandler` object must be created before being passed into
+  the `unobstructed_area_service_subscribe` method.
+* The Diorite emulator is still a little shy and will occassionally shake upon
+  starting. If your emulator doesn't stop shaking, try installing an app - that
+  usually brings it out of its shell.
