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.

- 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
- 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize

- ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" in two different windows

use "##" to pass a complement to the ID that won't be visible to the end-user:
Button("Play##0"); // Label = "Play", ID = hash of "Play##0"

- Occasionally/rarely you might want change a label while preserving a constant ID. This allows you to animate labels.
For example you may want to include varying information in a window title bar (and windows are uniquely identified by their ID.. obviously)

Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above)
sprintf(buf, "My game (%f FPS)###MyGame");

- use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window.

- When working with trees, ID are used to preserve the opened/closed state of each tree node.
Depending on your use cases you may want to use strings, indices or pointers as ID.
e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change.
e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense!

Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13)
A: Use the font atlas to load the TTF file you want:
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
Q: How can I load multiple fonts?
A: Use the font atlas to pack them into a single texture:
ImGuiIO& io = ImGui::GetIO();
ImFont* font0 = io.Fonts->AddFontDefault();
ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels);

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.

- 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 a window (to get/set other settings)
