According to upstream, this is the last planned Qt4 release.
A list of changes since 4.8.6 can be found here:

Porting notes and changes:
- Remove several patches that have been upstreamed.
- Make Uses/qmake.mk pass the contents of LIBS to the qmake environment. [1]
- Repurpose devel/qt4/files/extrapatch-src-corelib-global-qglobal.h now the
original patch is part of the release (curiously enough, the original
patch was never actually used, as the ?= assignment in r362837 after
r362770 was never possible).
This works around the way compiler support for C++11 features is detected
in Qt 4.8.7: while it originally only uses the compiler to determine if
something is supported or not, the initializer lists feature also depends
on the C++ standard library being used. It's a problem in FreeBSD 9.x,
where USES=compiler:c++0x or USES=compiler:c++11-lang means we will use
clang to build a port but use libstdc++ from base (GCC 4.2). The latter
obviously does not support initializer lists, and the build fails because
Qt tries to include headers that do not exist (<initializer_list>).
Since detecting libstdc++'s version is not trivial (we need to include a
non-lightweight header like cstdio and then check for __GLIBCXX__), we
just enable Q_COMPILER_INITIALIZER_LISTS support only when libc++ is used
(there should be no reason for someone to be using clang with GCC 4.8's
libstdc++, for example).
x11/kdelibs4's FindQt4.cmake had to include a backported change from the
upstream FindQt4.cmake in CMake itself to use a C++ compiler to detect
flags like Q_WS_X11, otherwise the inclusion of <ciso646> in qglobal.h
makes the build fail.
This patch contains changes by me, makc@ and alonso@.
