Version 1.12.1 - 2024
=========================
*fixed horizontal scroll with track pad ignored.
*reduce initial file load time
*ignore encoding errors during merge this will become a warning.
*adjust flatpak default flags.
*drop unused Qt6Core5Compat depenancy check.

Log message:
*: Recursive revbump from audio/flac-1.5.0

Log message:
kdiff3: rework patch and add upstream bug report URL

Log message:
kdiff3: fix build

Log message:
kdiff3: update to 1.12.0.

Version 1.12.0 - 2024
=========================

*Completed port away from Qt5, 6.6 now required version due to delayed ICU \ 
support in Qt
*Fixed UTF-8-BOM output encoding issues mustly seen on windows.
*horizontal scroll correctly comptuted for diff windows
--Note due to changes in windows/Qt the scrollbars may be vary small or hidden \ 
on Windows 11. This cann't be controlled from kdiff3.
*False errors on first launch with files selected should be fixed.

Version 1.11.x - 2024
===========================
*Fix false memory error when using "admin://" protocol
*Cleanup BOM handling lock detection to only known UTF-* encodings that use it.
*Fix bugged connection to non-existent signal (This is why we now use new style \ 
connections only.)
*fix crash in  Diff3Line::getLineData when doing history check for nonexistent lines.
*fix crash on some setups that create 0 height widgets when no data is loaded.
*Fixed encoding handling for non-UTF encodings
*Fixed encoding detection for lower case 'HTML' and 'XML' tags
*Fix handling of KIO jobs for non-file urls.
-Actually wait for secondary event loop to end (Not sure if this is documention \ 
bug in qt or behavior bug.)
-Don't arbitrarily kill jobs when progress dialog is hidden.
*Fix possible invalid line given by mousedown in Overview pane. (Caught by \ 
SafeInt range checking)
*Fix bad algorithm in getBestFirstLine.
-Related regression also fixed (BUG:486909)
*craft based builds are now Qt6/kf6.

Log message:
devel/extra-cmake-modules: Use buildlink3.mk, not TOOL_DEPENDS.

This one is borderline: should it be BUILD_DEPENDS or TOOL_DEPENDS?
It doesn't appear to vary depending on the build environment, so it
doesn't meaningfully describe the cross-builder vs the target system.
It is used only at build-time, but it doesn't have any native
executables -- they're just source code cmake scripts.

For now, it is convenient to use a buildlink3.mk file because this
enables us to explicitly expose only files under share/ECM/ -- and
not other random files installed in the prefix -- via buildlink3 to
keep dependent package builds clean.  Eventually we should have the
same mechanism for TOOL_DEPENDS but that day has not yet come.

This change creates a new use of BUILDLINK_DEPMETHOD build for
extra-cmake-modules, which is a priori risky.  Fortunately,
extra-cmake-modules has no libraries, so this is unlikely to cause
trouble.
