Changes

This is a followup to v1.89, v1.89.1, v1.89.2, v1.89.3, v1.89.4, v1.89.5, v1.89.6, v1.89.7. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

I have been stubbornly deferring tagging 1.90 for while because I wanted to include the range-select feature in it, but it's not done... But there are about 600 lines of changelog between 1.89 and 1.89.8.

Breaking Changes:

IO: Obsoleted io.ClearInputCharacters() (added in 1.47) as it now ambiguous and often incorrect/misleading considering the existence of a higher-level input queue. This is automatically cleared by io.ClearInputsKeys(). (#4921)
ImDrawData: CmdLists[] array is now owned, changed from ImDrawList** to ImVector<ImDrawList*>. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). Allocation count are identical. (#6406, #4879, #1878)

Other Changes:

Fonts: ImFontConfig::OversampleH now defaults to 2 instead of 3, since the quality increase is largely minimal.
Fonts, imgui_freetype: Added support to render OpenType SVG fonts using lunasvg. Requires enabling IMGUI_ENABLE_FREETYPE_LUNASVG along with IMGUI_ENABLE_FREETYPE, and providing headers/libraries for lunasvg. (#6591, #6607) [@sakiodre]
ImDrawData: CmdLists[] array is now an ImVector<> owned by ImDrawData rather than a pointer to internal state.
- This makes it easier for user to create their own or append to an existing draw data. Added a ImDrawData::AddDrawList() helper function to do that. (#6406, #4879, #1878)
- This makes it easier to perform a deep-swap instead of a deep-copy, as array ownership is now clear. (#6597, #6475, #6167, #5776, #5109, #4763, #3515, #1860)
- Syntax and allocation count are otherwise identical.
Fixed CTRL+Tab dimming background assert when target window has a callback in the last ImDrawCmd. (#4857, #5937)
IsItemHovered: Fixed ImGuiHoveredFlags_ForTooltip for Keyboard/Gamepad navigation, got broken prior to 1.89.7 due to an unrelated change making flags conflict. (#6622, #1485)
InputText: Fixed a case where deactivation frame would write to underlying buffer or call CallbackResize although unnecessary, in a frame where the return value was false.
Tables: fixed GetContentRegionAvail().y report not taking account of lower cell padding or of using ImGuiTableFlags_NoHostExtendY. Not taking it into account would make the idiom of creating vertically bottom-aligned content (e.g. a child window) inside a table make the parent window erroneously have a scrollbar. (#6619)
Tables: fixed calculation of multi-instance shared decoration/scrollbar width of scrolling tables, to avoid flickering width variation when resizing down a table hosting a child window. (#5920, #6619)
Scrollbar: layout needs to take account of window border size, so a border size will slightly reduce scrollbar size. Generally we tried to make it that window border size has no incidence on layout but this can't work with thick borders. (#2522)
IO: Added io.ClearEventsQueue() to clear incoming inputs events. (#4921)
May be useful in conjunction with io.ClearInputsKeys() if you need to clear both current inputs state and queued events (e.g. when using blocking native dialogs such as Windows's ::MessageBox() or ::GetOpenFileName()).
IO: Changed io.ClearInputsKeys() specs to also clear current frame character buffer (what now obsoleted io.ClearInputCharacters() did), as this is effectively the desirable behavior.
Misc: Added IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION config macro to disable stb_sprintf implementation when using IMGUI_USE_STB_SPRINTF. (#6626) [@septag]
Misc: Avoid stb_textedit.h reincluding string.h while in a namespace, which messes up with building with Clang Modules. (#6653, #4791) [@JohelEGP]
Demo: Better showcase use of SetNextItemAllowOverlap(). (#6574, #6512, #3909, #517)
Demo: Showcase a few more InputText() flags.
Backends: Made all backends sources files support global IMGUI_DISABLE. (#6601)
Backends: GLFW: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFlags_NoMouse if desired. (#5625, #6609) [@scorpion-26]
Backends: WebGPU: Update for changes in Dawn. (#6602, #6188) [@williamhCode]
Examples: Vulkan: Creating minimal descriptor pools to fit only what is needed by example. (#6642) [@SaschaWillem]

Changes from 1.89.7 to 1.89.8 related to the docking branch (multi-viewport and docking features):

Docking, Style: resizing separators use same colors as window borders (ImGuiCol_Border) for consistency. With default styles it doesn't make a big difference. (#2522) [@rmitton] In the future if we promote using thick value for inner/outer docking padding we may need to introduce new colors for it.
Docking: added style.DockingSeparatorSize, ImGuiStyleVar_DockingSeparatorSize. Now also scaled by style.ScaleAllSizes(). (#3481, #4721, #2522) [@PossiblyAShrub, @wobbier]
Docking: fixed rendering of docked-window scrollbar above outer border. (#2522)

Changes from 1.89.7 to 1.89.8 related to the range-select branch:

This is hopefully the last batch of breaking changes before merging this in 1.90:

RangeSelect/MultiSelect: (BREAKING) BeginMultiSelect() doesn't need two last params maintained by users. Moving some storage from user to core.
RangeSelect/MultiSelect: Added fields in ImGuiMultiSelectIO to facilitate implementing deletion while providing correct scrolling/focus.
RangeSelect/MultiSelect: Added multi-select deletion demo.

New exciting projects!

Since 1.89 we semi-sneakily soft launched two new entire projects!
