@ -42,6 +42,23 @@ HOW TO UPDATE?
Breaking changes:
- BeginChild(): Upgraded 'bool border = false' parameter to 'ImGuiChildFlags flags'.
Added ImGuiChildFlags_Border value. As with our prior "bool-to-flags" API updates,
the ImGuiChildFlags_Border value is guaranteed to be == true forever to ensure a
smoother transition, meaning all existing calls will still work.
If you want to neatly transition your call sites:
Before: BeginChild("Name", size, true)
After: BeginChild("Name", size, ImGuiChildFlags_Border)
Before: BeginChild("Name", size, false)
After: BeginChild("Name", size) or BeginChild("Name", 0) or BeginChild("Name", size, ImGuiChildFlags_None)
Kept inline redirection function (will obsolete later) so existing code will work.
- BeginChild(): Added child-flag ImGuiChildFlags_AlwaysUseWindowPadding as a replacement for
the window-flag ImGuiWindowFlags_AlwaysUseWindowPadding: the feature only ever made sense
for use with BeginChild() anyhow, passing it to Begin() had no effect. Now that we accept
child-flags we are moving it there. (#462)
Before: BeginChild("Name", size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding);
After: BeginChild("Name", size, ImGuiChildFlags_AlwaysUseWindowPadding, 0);
Kept inline redirection enum (will obsolete later) so existing code will work.
- Debug Tools: Renamed ShowStackToolWindow() ("Stack Tool") to ShowIDStackToolWindow() ("ID Stack Tool"),
as earlier name was misleading. Kept inline redirection function. (#4631)
- IO: Removed io.MetricsActiveAllocations introduced in 1.63, was displayed in Metrics and unlikely to

Other changes:
- Nav: Tabbing always enable nav highlight when ImGuiConfigFlags_NavEnableKeyboard is set.
Previously was inconsistent and only enabled when stepping through a non-input item.
(#6802, #3092, #5759, #787)
- Windows:
- BeginChild(): Added ImGuiChildFlags_ResizeX and ImGuiChildFlags_ResizeY to allow resizing
child windows from the bottom/right border (toward layout direction). Resized child windows
settings are saved and persistent in .ini file. (#1666, #1496, #1395, #1710)
- BeginChild(): Added ImGuiChildFlags_Border as a replacement for 'bool border = true' parameter.
- BeginChild(): Internal name used by child windows now omits the hash/id if the child
window is submitted in root of id stack of parent window. Makes debugging/metrics easier
and shorter to read in many cases.
- Popups: clarified meaning of 'p_open != NULL' in BeginPopupModal() + set back user value
to false when popup is closed in ways other than clicking the close button. (#6900)
- Can also auto-resize by double-clicking lower-left resize grip (not only lower-right one).
- Double-clicking lower-left resize grip auto-resize (like lower-rightone).
- Double-clicking bottom or right window border auto-resize on a singles axis.
- Use relative mouse movement for border resize when the border geometry has moved
(e.g. resizing a child window triggering parent scroll) in order to avoid resizing
feedback loops. Unless manually mouse-wheeling while border resizing. (#1710)
- Separators:
- Altered end-points to use more standard boundaries. (#205, #4787, #1643)
Left position is always current cursor X position.
Right position is always work-rect rightmost edge.
- Effectively means that:
Left position is always current cursor X position, right position is always work-rect
rightmost edge. It effectively means that:
- A separator in the root of a window will end up a little more distant from edges
than previously (essentially following WindowPadding instead of clipping edges).
- A separator inside a table cell end up a little distance from edges instead of

- MenuBar: Fixed an issue where layouting an item in the menu-bar would erroneously
register contents size in a way that would affect the scrolling layer.

- InputText:
- InputTextMultiline: Fixed a crash pressing Down on last empty line of a multiline buffer.
(regression from 1.89.2, only happened in some states). (#6783, #6000)
- InputTextMultiline: Fixed Tabbing cycle leading to a situation where Enter key wouldn't
be accepted by the widget when navigation highlight is visible. (#6802, #3092, #5759, #787)

- TreeNode: Added ImGuiTreeNodeFlags_SpanAllColumns for use in tables. (#3151, #3565, #2451, #2438)
- TabBar: Fixed position of unsaved document marker (ImGuiTabItemFlags_UnsavedDocument) which was
accidentally offset in 1.89.9. (#6862) [@alektron]

- BeginGroup(): Fixed a bug pushing line lower extent too far down when called after a call
to SameLine() followed by manual cursor manipulation.
- BeginCombo(): Added ImGuiComboFlags_WidthFitPreview flag. (#6881) [@mpv-enjoyer]
- BeginListBox(): Fixed not consuming SetNextWindowXXX data when returning false.
- Fonts:
- Arument 'float size_pixels' passed to AddFontXXX() functions is now rounded to lowest integer.
- Argument 'float size_pixels' passed to AddFontXXX() functions is now rounded to lowest integer.
This is because our layout/font system currently doesn't fully support non-integer sizes. Until
it does, this has been a common pitfall leading to more or less subtle issues. (#3164, #3309, #6800)
- Better assert during load when passing truncated font data or wrong data size. (#6822)
- Ensure calling AddFontXXX function doesn't invalidates ImFont's ConfigData pointers
prior to building again. (#6825)
- imgui_freetype: Fixed a warning and leak in IMGUI_ENABLE_FREETYPE_LUNASVG support. (#6842, #6591)
- Inputs: Added IsKeyChordPressed() helper function e.g. IsKeyChordPressed(ImGuiMod_Ctrl | ImGuiKey_S).
(note that ImGuiMod_Shortcut may be used as an alias for Cmd on OSX and Ctrl on other systems).
- Misc: Most text functions also treat "%.*s" (along with "%s") specially to avoid formatting. (#3466, #6846)
- IO: Add extra keys to ImGuiKey enum: ImGuiKey_F13 to ImGuiKey_F24. (#6891, #4921)

Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."
