28 November 2009
NEW: The value of the PopupSize property is used as the default docked size for a window, if set.
FIX: When changing to the last tab with integral close buttons, the close button could fail to become entirely visible.
FIX: Some tab rendering glitches have been corrected.
FIX: When restoring a layout in an MDI container form, the Activated event could be raised for all windows.

FIX: Trying to resize two split layouts that were already below minimum size could result in an exception.
FIX: An exception could occur shortly after deserializing layout, after serializing a specific set of windows.
FIX: The font used to draw both the titlebar and tab for a window is now the window's font.
FIX: It was possible to drag a floating window such that its resulting titlebar was inaccessible.
FIX: An ellipsis would be shown on a document tab when integral close was enabled but the document was not closable, and the document had the focus.
FIX: Maximums are now enforced when dragging a large docked window around in a narrow container so that windows do not become inaccessible.

NEW: Windows Forms Validation events are now raised when the user attempts to change tabs.
FIX: A GDI+ exception could be thrown by the Office 2007 Renderer when the main window was made very small.
FIX: When pinning a window in an MDI scenario, the first MDI child could be activated by Windows Forms.
FIX: An IndexOutOfRangeException could be thrown when opening a window with a specific history of movements.
FIX: Saving the window layout while all windows were minimized and invisible would result in floating windows being inaccessible upon layout deserialization.
FIX: Shift and Alt keys no longer cancel an interactive docking operation.
FIX: Windows could be docked into existing floating groups even if their AllowFloat property was set to false.

FIX: Docking a floating document containing an ActiveX instance of Word 2007 under Windows Vista could throw an exception.
FIX: Clicking the left mouse button on the titlebar of a floating window would not activate that window.
FIX: When using IntegralClose with document tabs, the close button could overlay the scroll left and scroll right buttons.
FIX: An OverflowException could be thrown when minimizing a form with a SandDock layout, in very specific circumstances.
IMPROVED: Detection added for the situation where a layout is placed within a ToolStripContentPanel and could therefore receive incorrect layout information.
5 April 2007
FIX: A bug introduced in the last build could prevent some customers from being able to redock windows at design time.
FIX: Showing a window restored (but hidden) with layout deserialization could result in the window being the wrong size.

FIX: When resizing a popped up, collapsed window, you are now constrained to resizing within the bounds of the dock system container.
28 December 2006
NEW: IntegralClose property allows the close button to be positioned within the tab itself rather than the containing strip.
NEW: Clicking on most controls within a dockable window will activate that window even if the controls do not take focus (like in VS).
NEW: PrimaryControl property added to windows for designation of the control that is focused when the window is activated.
FIX: Right-clicking on the titlebar to get the context menu for a window did not work (introduced in 2.3.4)

FIX: Hovering over any SandDock UI could increase CPU usage under the Vista DWM.
FIX: Artifacts could be displayed in the translucent window preview under the Vista DWM.
FIX: Opening a TabPage in the designer with child controls that used anchoring could result in the child controls assuming the full size of the TabPage.
17 October 2006
NEW: DocumentOverflow property on SandDockManager indicates whether scrolling or an active files menu is used to access document tabs.
NEW: A local BindingContext can be assigned to a dockable window, and if it is, the window will no longer use the BindingContext from the manager.
NEW: Floating windows can now be redocked and otherwise manipulated in Windows Vista under the DWM.
NEW: Even further improved support for remembering the last positions of windows after deseralizing a window layout.
FIX: Switching to a document after a substantial expansion of client area size could result in visual flicker as the document was shown.

FIX: Data binding on a standalone DockControl (while designing) now works correctly.
FIX: Loading a layout which does not reference an open window with CloseAction set to Dispose will now dispose the window as well as hiding it.
12 February 2006
FIX: In the Whidbey renderer there was a small graphical omission of a separator between tabs in docked tabstrips.
FIX: In the Whidbey renderer the gap between document tabs was too small.

23 October 2005
NEW: SelectedIndex property added to TabControl.
NEW: When initially adding SandDock to a form, it will pick the most likely container to act as the container for your dockable windows. Previously it would always use the root component.

NEW: Further improved docking "memory" by remembering more information about previous window locations.
NEW: SelectTabsOnDrag property added to SandDock manager to control OLE drag over behaviour.

FIX: Docking indications more accurately reflect the eventual size of the committed dock operation.
FIX: An empty dockable window with a border cause leave visible artifacts as the window was resized.
FIX: When removing TabPages from a TabControl the selected page would not always be updated to the next available page correctly.
CHANGE: The image assigned to the TabImage property is not disposed when the DockControl is disposed.

FIX: When SandDock was used on an MDI parent, docking operations could result in SandDock windows being placed the wrong side of other side-docked controls.
CHANGE: TabControl no longer derives from DockContainer and TabPage no longer derives from DockControl. They are both separate controls in their own right.

FIX: When showing a context menu on a popped up, collapsed DockControl the menu could sometimes be in the wrong position.
FIX: Setting AllowDock* to false now prevents redocking of a floating window by double-clicking its titlebar.
FIX: When calling Open() on a tabbed document with a certain configuration of floating windows visible, the document could be opened in the wrong container.
FIX: A lone docked window would not always correctly remember its size when being closed then re-opened.
FIX: When calling Close() on a dockcontrol that was not open, it would not be disposed if CloseAction was set to Dispose.
