                             wxWidgets Change Log
-------------------------------------------------------------------------------

Note: This file contains the list of changes since wxWidgets 3.x, please see
      docs/changes_30.txt for the changes in the previous versions.


INCOMPATIBLE CHANGES SINCE 3.0.x:
=================================

Changes in behaviour not resulting in compilation errors
--------------------------------------------------------

- wxRibbonButtonBar::DeleteButton() now deletes and not just removes the button.
- Default interpolation mode in wxGDIPlusContext under MSW is now
  wxINTERPOLATION_DEFAULT and not wxINTERPOLATION_GOOD as in 3.0 for
  consistency with OS X, call SetInterpolationQuality() explicitly if needed.

- Calling wxYield() in wxMSW now generates wxEVT_IDLE events, just as in the
  other ports, but this can be unexpected for the applications not expecting
  their idle handlers to be called from inside wxYield().

- Creating wxBitmap with 0 width or height now always fails in all ports
  (it used to succeed in wxMSW).

- Using invalid flags with wxBoxSizer or wxGridSizer items now triggers asserts
  when done from the code or error messages when done in XRC.

Changes in behaviour which may result in build errors
-----------------------------------------------------

- "webview" library is not included in `wx-config --libs` output any more, you
  need to request it explicitly, e.g. `wx-config --libs std,webview`.

- WXWIN_OS_DESCRIPTION doesn't exist any longer, use wxGetOsDescription().


3.1.0: (released 2015-xx-xx)
----------------------------

- Many improvements for high DPI monitors support, notably XRC now interprets
  all pixel values as being in resolution-independent pixels.
