Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
Also read releases logs https://github.com/ocornut/imgui/releases for more details.
- 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDraw::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337).
- 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
- 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).

io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese());
Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. ImGui will support UTF-8 encoding across the board.
Character input depends on you passing the right character code to io.AddInputCharacter(). The example applications do that.
A: When loading a font, pass custom Unicode ranges to specify the glyphs to load.
All strings passed need to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese CP-1251 for Cyrillic) will not work.
In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code.
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application
As for text input, depends on you passing the right character code to io.AddInputCharacter(). The example applications do that.
- tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
- tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
- tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window. this is also useful to set yourself in the context of another window (to get/set other settings)

- style: WindowPadding needs to be EVEN needs the 0.5 multiplier probably have a subtle effect on clip rectangle
- text: simple markup language for color change?
- font: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
- font: helper to add glyph redirect/replacements (e.g. redirect alternate apostrophe unicode code points to ascii one, etc.)
- font: fix AddRemapChar() to work before font has been built.
- log: LogButtons() options for specifying depth and/or hiding depth slider
- log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
- log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)

- style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438)
- style editor: color child window height expressed in multiple of line height.
- remote: make a system like RemoteImGui first-class citizen/project (#75)
!- demo: custom render demo pushes a clipping rectangle past parent window bounds. expose ImGui::PushClipRect() from imgui_internal.h?
- drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
- examples: directx9: save/restore device state more thoroughly.
- examples: window minimize, maximize (#583)
