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.
- 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
- 2016/02/21 (1.48) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to ColorEdit*() functions
- replaced ColorEdit4() third parameter 'bool show_alpha=true' to 'ImGuiColorEditFlags flags=0x01' where ImGuiColorEditFlags_Alpha=0x01 for dodgy compatibility
- 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.

- main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
- main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
- input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
- input text: reorganise event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
- input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
- input text multi-line: way to dynamically grow the buffer without forcing the user to initially allocate for worse case (follow up on #200)
- input text multi-line: line numbers? status bar? (follow up on #200)
