0.6.0

Released: Fri July 19 2013

• [feature] Added new kw argument to EnvironmentContext.configure()
include_object. This is a more flexible version of the
  include_symbol argument which allows filtering of columns as well as tables
  from the autogenerate process,
  and in the future will also work for types, constraints and
  other constructs. The fully constructed schema object is passed,
  including its name and type as well as a flag indicating if the object
  is from the local application metadata or is reflected.

• [feature] The output of the alembic history command is now
  expanded to show information about each change on multiple
  lines, including the full top message,
  resembling the formatting of git log.

• [feature] Added alembic.config.Config.cmd_opts attribute,
  allows access to the argparse options passed to the
  alembic runner.

• [feature] Added new command line argument -x, allows extra arguments
  to be appended to the command line which can be consumed
  within an env.py script by looking at
  context.config.cmd_opts.x, or more simply a new
  method EnvironmentContext.get_x_argument().

• [bug] Added support for options like "name" etc. to be rendered
  within CHECK constraints in autogenerate. Courtesy

• [misc] Source repository has been moved from Mercurial to Git.

• [bug] Repaired autogenerate rendering of ForeignKeyConstraint
  to include use_alter argument, if present.

• [feature] Added -r argument to alembic history command,
  allows specification of [start]:[end] to view
  a slice of history. Accepts revision numbers, symbols
  "base", "head", a new symbol "current" representing the
  current migration, as well as relative ranges for one
  side at a time (i.e. -r-5:head, -rcurrent:+3).
  Courtesy Atsushi Odagiri for this feature.

• [feature] Source base is now in-place for Python 2.6 through
  3.3, without the need for 2to3. Support for Python 2.5
  and below has been dropped. Huge thanks to
  Hong Minhee for all the effort on this!
