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.
- 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is really usable in typical conditions at the moment.
- 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
- 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
- 2018/02/07 (1.60) - reorganized context handling to be more explicit,
- YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.

this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
- if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
- the signature of the io.RenderDrawListsFn handler has changed!
ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
became:
ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
argument 'cmd_lists' -> 'draw_data->CmdLists'
argument 'cmd_lists_count' -> 'draw_data->CmdListsCount'
ImDrawList 'commands' -> 'CmdBuffer'
ImDrawList 'vtx_buffer' -> 'VtxBuffer'
ImDrawList n/a -> 'IdxBuffer' (new)
ImDrawCmd 'vtx_count' -> 'ElemCount'
ImDrawCmd 'clip_rect' -> 'ClipRect'
ImDrawCmd 'user_callback' -> 'UserCallback'
ImDrawCmd 'texture_id' -> 'TextureId'
old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
argument: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
- each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
- if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
- refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!

- 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
(1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
this sequence:
const void* png_data;
unsigned int png_size;
ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size);
// <Copy to GPU>
became:
unsigned char* pixels;
int width, height;
io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
// <Copy to GPU>
io.Fonts->TexID = (your_texture_identifier);
you now have much more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs.
font init: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); <..Upload texture to GPU..>
became: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); <..Upload texture to GPU>; io.Fonts->TexId = YourTextureIdentifier;
you now more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs.
it is now recommended that you sample the font texture with bilinear interpolation.
(1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID.
(1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
