.. _version-0.95.3:

assigns public IPs for non-default VPC clusters by default now because of the
following issues:

1. It opens up the VPC to the internet by default which is a security risk
2. It requires a special VPC configuration (internet gateway attached to the
VPC and a route to the gateway with dest CIDR block 0.0.0.0/0 associated
with the VPC subnet). Configuring this automatically (which does not happen
currently) would be a security risk and without this configuration
StarCluster cannot connect to the VPC nodes even though they've been
assigned a public IP. See :ref:`connect-vpc` for more details.

Users can still enable public IPs for their non-default VPC clusters via the
``PUBLIC_IPS`` config setting or the new ``--public-ips`` option to the
``start`` command assuming they've properly configured their VPC to use public
IPs. If the VPC hasn't been properly configured for public IPs an error will be
raised during validation. The ``--no-public-ips`` option has been preserved so
that users can disable the config setting (``PUBLIC_IPS``) from the ``start``
command. Please see :ref:`using-vpc` and :ref:`connect-vpc` for more details.

Please note that this version is *not* compatible with clusters started with
older versions of StarCluster. Please terminate all clusters before upgrading
to 0.95.3.

--------
* start: add -Q, -p, and --no-spot-master options
* cluster: update 'Creating cluster' log msg to indicate VPC

* cluster: do not use public IPs with VPC by default (372)
* cluster: fix VPC public IPs validation
