 Changelog
 
+# 0.11.0 (12 jul 2017)
+# 0.11.0-c (10 jul 2017)
+- fix: Also closing file descriptor after removing current print file (commit 550e151)
+
+# 0.11.0-b (6 jul 2017)
+- show id of current print in d3dapi/info/status when printing in 'fetch' mode.
+- code reuse and cleanup for control, kill and status
+
+# 0.11.0-a (23 jun 2017)
+- Added 'fetch' functionality to let the WiFi-Box print from a remote server. This enables the WiFi-Box to print large g-code files. (yeah!)
+- Added support for the Renkforce RF100 printer.
+- Changed 'default startcode' to prevent Ultimaker 2 series to bump into platform [#21](https://github.com/Doodle3D/WiFi-Box/issues/21) when Ultimaker (original) is selected.
+- Changed default nozzle temperature from 230 to 210 °C.
+- Fixed corrupted endcode for delta printers.
+- Changed default endcode to cooldown to 0 after print instead of cooling down to preheat temperature.
+
+# 0.10.12
+# 0.10.12-b (12 jan 2017)
+- Post install update to config for changes in 0.10.10 (fixes print3d logging)
+
+# 0.10.12-a (26 jul 2016)
+- Added Ultimaker Original Plus (Thanks Remco)
+- Added extra usb drivers
+
 # 0.10.11
 # 0.10.11-a (25 may 2016)
 - After pressing the reset button for about 4 seconds the WiFi-Box will go to access point mode. Useful for when you can't reach it.
-- Becomes access point when it can't connect to WiFi network. 
+- Becomes access point when it can't connect to WiFi network.
 - Handles more clients by tweaking the uhttpd config.
 - Print3D isn't killed when there is no memory available.
 - New banner (shown after ssh login)
