New :ref:`merging<merging>` suffixes ``~`` and ``-~`` can be used
to **modify or remove data based on regular expressions**. For
example, renaming all required packages can be done easily in this
way::
require~: /python2-/python3-/
The :py:func:`fmf.filter()` function now supports **searching by
node name**. Just specify the desired name instead of the ``key:
value`` pair. For example, to search for all tests with the name
starting with ``/test/core`` and tag ``quick`` you can do::
/tests/core/.* & tag: quick
It is now possible to **escape boolean operators** ``|`` and ``&``
as well. This allows to use more complex regular expressions like
this::
tag: Tier(1\|2\|3)
The new :ref:`select<select>` directive can be used to **include
branch nodes or skip leaf nodes** when searching the tree using
the :py:meth:`fmf.Tree.climb` method.
The :py:meth:`fmf.Tree.adjust` method now supports new parameter
``additional_rules`` for providing **additional adjust rules**
which are applied after the rules detected in the node itself.
