  * Fixed issue with ''CF.loadGUI'' not loading the default GUI when passed an empty string
  * Fixed issue with JS not receiving proper network information after a GUI switch
  * Fixed status bar appearance issue when set to ''CF.STATUS_BAR_BLACK_TEXT''

===== Version 4.0.303 =====
> **Date Released (iViewer 4):** April 14th, 2014

  * Improved application memory handling so as to reduce the chances for the OS (in particular iOS 7) jettisoning the app when it needs to claim memory

  * Fixed an issue where iViewer would not detect that the WiFi network is active when the device is connected in AdHoc mode. 
  * Fixed ''CF.loadAsset()'' constants (''CF.CACHE'' and ''CF.NO_CACHE'' values were swapped, resulting in ''CF.CACHE'' not working as expected)
  * Fixed ''CF.unwatch()'' calls when un-watching a watch that had specific parameters

===== Version 4.0.292 =====
> **Date Submitted (iViewer Next):** January 7th, 2014

  * Improved ''CF.listContents'' to now return all values and items, including those not backed by actual GUI elements in the    list
  * Implemented new ''CF.StatusBarAppearanceProperty'' for ''CF.setDeviceProperty'', with accepted values ''CF.STATUS_BAR_HIDDEN'', ''CF.STATUS_BAR_WHITE_TEXT'' and ''CF.STATUS_BAR_BLACK_TEXT'' (last two values produce the same result, showing the status bar, on OS versions prior to iOS 7)
  * Fixed networking issues with Bonjour browsing, iViewer Protocol, and TCP SSL connections
  * Fixed iOS 7 issues with text field placeholders not always displayed and URLs with certain non-ascii characters not being URL-encoded the same way they were in previous releases.

===== Version 4.0.282 =====
> **Date Release (iViewer):** September 24th, 2013

  * iOS 7 compatibility
  * New **tags** support: every object in the GUI that carries a join can be augmented with arbitrary tags attached to it. Any time a join is referenced, tags can be substituted. Uses include grouping radio buttons, grouping objects for easily changing their properties, accessing objects in a generic fashion from modules that don't need to be tied to specific join numbers, etc.
  * New multiple control systems: iViewer now supports multiple "control" systems (systems that talk the iViewer protocol and receive join updates). As a side effect, the single "control system" is now going away from guiDesigner and automatically migrated to being placed in the overall list of systems. This also provides better consistency for newcomers.
  * New options for TCP client systems: 'Dialog' mode (send data and expect reply before disconnecting) with dialog timeout, and idle timeout for non-always-on systems. 
  * Improved networking reliability
  * TCP server systems now execute their startup command/macro on each incoming connection, and now properly honor the //Queue messages when offline// option

  * Added support for https connections to sites with self-signed certificates in web view
  * Fixed issues with sliders, networking, Bonjour, status bar, subpage hide/show animations, video stop trigger

===== Version 4.0.254 =====
> **Date Release (iViewer Next):** April 4th, 2013

  * Added new ''CF.networkType'' and ''CF.networkSSID'' JavaScript variables to help determining which network the device is on. Global tokens ''[networkType]'' and ''[networkSSID]'' were also added.
  * Improved overall network performance: faster and more reliable reconnections, more accurate network status detection, better handling of multiple simultaneous [[http://commandfusion.com/docs/scripting/net.html#cF.request|CF.request()]] calls
  * Improved caching support with cache and pre-caching control via [[http://commandfusion.com/docs/scripting/util.html#cF.loadAsset|CF.loadAsset()]]. New options have been added to precisely control the cache.
  * Fixed issues with MJPEG streams display, sliders, screen rotation when status bar is displayed, and more. 
===== Version 4.0.242 =====
> **Date Released:** February 20th, 2013

==== JavaScript ====

  * New CF.loadGUI(url, options) API
  * New CF.device.uniqueIdentifier and CF.device.legacyUniqueIdentifier properties
  * CF.request() can now take no callback function (or a null callback) if you're not interested in the reply
  * CF.request() now accepts any method for an HTTP request, not just the base ones defined in the HTTP RFC. Allows easier integration with various protocols running on top of HTTP

  * New CF.guiURL variable containing the URL of the current GUI
  * CF.setProperties() can now update properties of joins in list items, using the standard list notation (listjoin:index:join) 
  * CF.watch() now outputs meaningful information to debugger log about invalid parameters
  * New Sensors API to access and read some device sensors. You can receive updates for the device's accelerometer, gyroscope, magnetometer and GPS so as to obtain acceleration, rotation, heading and location data
  * Gestures now provide the same context as buttons when executing associated JavaScript (join, list, listIndex and tokens variables in addition to the gesture variable)
  * Fixed issue with properties rotation around Y axis

==== Networking ====

  * New options for UDP systems to accept packets coming from any host and/or any port
  * Fixed networking connection and reconnection on wakeup issues
  * Fixed UDP issues with broadcast and multicast sockets
  * Fixed issue with receiving packets over UDP broadcast systems
  * Ensure loopback systems can run even when WiFi / 3G is turned off or disconnected.
  * Commands that do the optional value assignment were not unescaping their data when assigning to a list (assigning to a list is using the list protocol and requires some binary separators in the data)

==== General ==== 

  * Can now specify fonts to use with a platform (iOS, Android) font selector. Requires guiDesigner 2.5.0.0 or later.
  * Added "[uuid]" global token with device UUID
  * Better management on alerts, in particular connection loss / asset load warnings
  * Fixed critical issue with buttons in lists
  * Fixed text wrapping in labels with carriage return characters

  * Fixed several minor issues
  * Fixed issue with slider thumbs not being set their slider's opacity when using CF.setProperties()
  * Lists-in-lists (using headers and footers) are working again, even though not officially supported
  * Ensure join s0 is never set as the result of triggering an associated digital join (i.e. input field on join 0 with an associated digital join, triggering the digital join would set the contents of the input field to all objects on s0 in the GUI)


===== Version 4.0.215 =====
> **Date Released:** June 15th, 2012

==== Changes ====
  * Now issue a sensible log message through CF.log() if your JS tries to CF.send() before the end of the CF.userMain startup sequence
  * Improved the connection speed to TCP systems in some cases
  * Added new CF.ListWillStartScrollingEvent, CF.ListDidScrollEvent, CF.ListDidEndScrollingEvent for JS code to precisely know when a list scrolls

  * Allow CF.LastItem to be used in CF.listScroll() for absolute positioning
  * Fixed issue where slider's digital "pressed" join was being sent directly to main control system. Wasn't going through the internal join routing mechanism - no event fired to JS (confused users of CrestronMobile)
  * Fixed a crash case where an invalid group number if used in a feedback item group reference
  * Fixed an issue where in some cases, iViewer would fail reconnecting a TCP system
  * Fixed grammar in log messages issued by the remote debugger

  * Fixed an issue where subpages disappearing to left or top would appear to disappear faster than their programmed transition
  * Fixed issue were CF.openURL() would only work once
  * Fixed issue where main control system would be created as a loopback system if its IP address was initially set to 0.0.0.0 in the GUI XML
  * Fixed an issue in recent device identity changes. Device identity should now be stable
  * Fixed a couple hang and crash cases
  * Fixed an issue where scroll commands and macros would not fire when performing programmatic scrolling (i.e. CF.listScroll())

===== Version 4.0.207 =====
> **Date Released:** April 3, 2012

==== New Features ====
  * Added new CF.BatteryLevelProperty and CF.BatteryChargeStatusProperty properties for CF.DevicePropertyChangeEvent, allowing full monitoring of plugged / unplugged state and battery charge level in JavaScript. See http://www.commandfusion.com/docs/scripting-beta/changes.html for a list of changes. Also added new CF.device.batteryLevel and CF.device.batteryChargeStatus values in the CF.device object to reflect current values.

===== Version 4.0.206 =====
> **Date Released:** April 2, 2012

==== New Features ====
  * Added new CF.SoundOutputVolumeProperty for CF.DevicePropertyChangeEvent, and new CF.device.soundOutputVolume variable (read-only) that contains the current hardware output volume, a float number between 0.0 and 1.0.

===== Version 4.0.205 =====
> **Date Released:** April 2, 2012

==== Changes ====
  * Switching away from Apple's unique device identifier (UDID) which is deprecated in iOS 5 and is starting to cause app rejections. We now use a new, CommandFusion-generated identifier for each device. Compatibility with existing jobs is being preserved: if at first launch the app sees it's not using the default GUI, it sets itself up to use Apple's device identifier. We will be documenting the migration process in a separate document.
  * Fixed an issue where CF.setJoin() could not trigger "system features" like Show / Hide status bar (joins d17931 / d17932).

===== Version 4.0.204 =====
> **Date Released:** March 27th, 2012

==== New Features ====
  * Added a preference to enable all systems disconnection on app exit / device sleep. By default, this pref is turned off
  * Added new CF.device.screenBrightness property readable from JavaScript
  * Added new CF.setDeviceProperty() call, allowing to change the device brightness
  * Added new CF.DevicePropertyChangedEvent, allowing to monitor device property changes (currently, brightness only)

==== Fixes ====
  * Fixed a lockup on app suspend (that would materialize as a restart of the app next time you used it)

===== Version 4.0.203 =====
> **Date Released:** March 25th, 2012
> **Submitted to App Store:** NA

==== Fixes ====
  * Tuned networking code for connectivity issues
  * Make sure hostname-based systems' IP address get refreshed when needed
  * Fixes to connectivity issues after inactivity periods
  * Fixed alert that appears if the main control system's password is invalid (was appearing repeatedly)
  * iViewer now shuts down all connections when it is suspended, and reactivates them when coming back. Since iOS 5 now abruptly disconnects connections on power off, this safety measure ensures that connections are not left in a half-closed state from the remote's perspective.

===== Version 4.0.201 =====

> **Submitted to App Store:** NA

==== Fixes ====
=== General ===

  * Fixed issue where UDP system didn't properly reconnect after a connection loss on forced sleep
  * Startup command wasn't performing global token replacement, and can be sent to systems other than the one that just connected
  * Fixed a crasher in HTTP request processing
  * When iViewer comes back from suspended / background state (after spending more than 10s there), requery the main control system for all its join states

  * Added support for web views to run HTML embedded in the GUI assets (via zip file)
  * Added support for cross-references of feedback capture group names in onmatch targets.
  * Added pixel scroll position to CF.listInfo JavaScript callback.

=== Remote Debugger ===
  * Support remote debugging of unencrypted zip projects.

==== Issues Fixed ====

=== JavaScript ===
  * CF.GUISuspendedEvent will now be received by your JS code by the time the GUI is suspended. Some code can be executed at that time, but not too much (the application is going to background)
  * Join changes via CF.setJoin() and CF.setJoins() are now propagated through the Control System connection if one is defined.
