- The ``json`` module now uses an ``OrderedTable`` rather than a ``Table``

- De-deprecated ``re.nim`` because we have too much code using it

and it got the basic API right.

|

- ``split`` with ``set[char]`` as a delimiter in ``strutils.nim``
|

no longer strips and splits characters out of the target string
|

- The ``split`` `(doc) <http://nim-lang.org/docs/strutils.html#split,string,set[char],int>`_
|
||||
procedure in the ``strutils`` module (with a delimiter of type
|
||||
``set[char]``) no longer strips and splits characters out of the target string
|
||||
by the entire set of characters. Instead, it now behaves in a
|
||||
similar fashion to ``split`` with ``string`` and ``char``
|
||||
delimiters. Use ``splitWhitespace`` to get the old behaviour.
|
||||
|
||||
- The command invocation syntax will soon apply to open brackets
|
||||
and curlies too. This means that code like ``a [i]`` will be
|
||||
interpreted as ``a([i])`` and not as ``a[i]`` anymore. Likewise
