## Special notes about 2.7.20 ##

Puppet 2.7.20 address http://projects.puppetlabs.com/issues/15560,
which means if you had specifically enabled `managehome => true` for
user resources expecting it not to work on Windows, be aware that it
**works now** for both creation with `ensure => present` AND deletion
with `ensure => absent`. Previously deleted users will not have their
orphaned home directories removed, however.

Puppet 2.7.20 also addresses concerns regarding a change
introduced in Puppet 2.7.16, "b26699a (#10146) `-` is not legal in
variable names.", which disallowed the use of dashes in variable
names. Puppet 2.7.20 introduces a configuration option,
`allow_variables_with_dashes`,
(http://docs.puppetlabs.com/references/2.7.latest/configuration.html#allowvariableswithdashes)
which can be set to `true` to restore earlier behavior, although this
is strongly discouraged. The option is set to false by default to
maintain current behavior.

(#10146) `-` in variable names should be deprecated!

In commit b26699a2 I fixed an accidentally introduced change to the lexer,
allowing `-` to be part of a variable name. That had lasted for
a while and
was surprisingly popular. It was also hugely ambiguous around
`-` as minus,
and led to all sorts of failures - unexpected interpolations to nothing -
because of that.

A much better strategy would have been to deprecate the feature,
issue proper
warnings, and include an option to allow users to toggle the behaviour.

Initially defaulting that to "permit", and eventually toggling
over to "deny",
would have made the whole experience much smoother - even if this
was totally
documented as not working, and was a clear bug that it changed.

So, thanks to prompting from Benjamin Irizarry, we do just that:
introduce the
configuration option, default it to "deny" to match current behaviour, but
allow users the choice to change this back.

Please be aware that allowing variables with `-` might break all sorts of
things around, for example, Forge modules though. Most people
write code to
the documented standard, and their code might well totally fail
to work with
this changed away from the default!
