v101
----
 * Steps

   * Fixed an issue where using the step, ``cache_writer``, could cause
     an OutOfMemoryException.

 * Custom Step Development

   * Fixed an issue in ``silo.low_code.read_step_cache`` that did not
     properly cache a result to Memory which created a new instance
     every time it ran.

v100
----
 * General

   * Increased the performance by removing similar calls for all
     steps
   * Updated substitution to use standard Python substitution. Refer
     to :ref:`Substitution <substitution>` for additional information.
   * Custom substitution can now be functions which request
     any out-of-the-box substitution variables. Refer
     to :ref:`Substitution <substitution>` for additional information.
   * Deprecated ``<>`` for substitution. Use ``${}`` instead.
   * Implemented the ability for a Python wheel to automatically
     register with the Snippet Framework. See
     :ref:`Creating a wheel <sf_auto_reg>` for more information.
   * Fixed an issue where Oauth2 ResourceOwner would not correctly
     reference the field ``Additional body Parameters`` in
     ``Low-code tools: rest Credential``

 * Steps

   * Added the step, :ref:`jc <steps-jc>`, that provides general
     parsing.
   * Added the step, :ref:`snmp <steps-snmp>`, that can request
     data through SNMP.
   * Renamed the step, ``paginator_offset_limit``
     to ``paginator_offset``.
   * Updated the step, ``paginator_offset``, to allow `limit` and `offset`
     to be altered to meet the needs of the API.
   * Updated the step, ``http``, to specify how a token should be
     refreshed during the collection cycle. Refer to
     :ref:`Authentication <authentication>` for more information.
   * Deprecated the step, ``jsonpath``. Use ``jmespath``
     instead as it is more performant.
   * Deprecated the step, ``simple_key``. Use ``jmespath``
     instead as it utilizes the same syntax.
   * Deprecated the step, ``stringint``.
   * Deprecated the step, ``stringfloat``.
   * Fixed an issue with the step ``http`` where a URL could be
     created incorrectly.
   * Fixed an issue where the ``ssh`` requestor required a password
     or PEM key when aligning to an agent-based device.

     * ``step_args``
     * ``collection``

   * Updated ``Cacher`` custom step development to use the
     Standard Parameters
   * Updated ``Syntax`` custom step development to require
     a ``:`` to as the step name identifier
   * Created a new registration for ``RequestMoreData``
   * Added the flag to specify if a step is ``mutable`` which
     affects the de-duplication process. Refer to
     :ref:`Mutable Steps <mutable-step>` for more information.
   * Deprecated the Standard Parameter, ``result_container``
   * Deprecated the Standard Parameter, ``action_number``
   * Deprecated the Standard Parameter, ``action_arg``

   * Deprecated the ability for a Requestor to request the parameter
     ``request``
   * Deprecated the ability for a Cacher that does not consume
     Standard Parameters


 * Low-code tools: rest Credential

   * Updated the `Low-code tools: rest credential` to include
     `AuthOverride` which allows for custom authenticators.
   * Fixed an issue with the `Low-code tools: rest` credential
     where additional header fields were not always present.
   * Added a new field to specify the token refresh strategy
     as either key based (dynamic) or time based (static).
