If you have been using dear imgui for a while and/or have been using C/C++ for several years and/or have demonstrated good behavior here, it is ok to not fullfill every item to the letter. Those are guidelines and experienced users of dear imgui will know what information are useful in a given context.
## How to create an Pull Request
- If you are adding a feature, please explain the context of the change: what do you need the feature for?
- Make sure you create a branch for the pull request. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR.

@ -60,6 +60,7 @@ Breaking Changes:
- Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
- Obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
- Obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
- Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered style colors as the closing cross uses regular button colors now.
- Renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
- Removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
@ -101,6 +102,7 @@ Other Changes:
- Style: Enable window border by default. (#707)
- Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181)
- Style: Added style.MouseCursorScale help when using the software mouse cursor facility. (#939).
- Style: Close button nows display a cross before hovering. Uses button colors for highlight when hovering. (#707)
- Popup: OpenPopup() Always reopen existing popup. (Removed imgui_internal.h's OpenPopupEx() which was used for this.) (#1497, #1533).
- Popup: BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick() all react on mouse release instead of mouse press. (~#439)
- Popup: Better handling of user mistakenly calling OpenPopup() every frame (with reopen_existing option). The error will now be more visible and easier to understand. (#1497)

!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
- scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
- drawdata: make it easy to clone (or swap?) a ImDrawData so user can easily save that data if they use threaded renderering.
- drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
- drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
- drawlist: primtiives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api

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.
- 2018/03/12 (1.60) - Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
- 2018/03/08 (1.60) - Changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
- 2018/03/03 (1.60) - Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
- 2018/02/27 (1.XX) - removed io.DisplayVisibleMin, io.DisplayVisibleMax settings (it was used to clip within the DisplayPos..DisplayPos+Size range, I don't know of anyone using it)

- Output texture has excessive resolution (lots of vertical waste)
- Output texture has excessive resolution (lots of vertical waste).
- FreeType's memory allocator is not overridden.
- `cfg.OversampleH`, `OversampleV` are ignored (but perhaps not so necessary with this rasterizer).
