Update to 2.9.0:

--- 2.009 (2013-07-21 03:30)

  Mail::SPF:
  * Default to querying only TXT type RRs (query_rr_types = Mail::SPF::Server->
    query_rr_type_txt).  Experience has shown that querying SPF type RRs is
    impractical.

--- 2.008 (2012-01-30 08:15)

  Mail::SPF:
  * Sanitize result local_explanation (as well as result object string
    representation) by replacing all non-printable or non-ascii characters
    with their hex-escaped representation (e.g., "\x00").
    (Addresses: bugs.launchpad.net #806926)

  Miscellaneous:
  * Change openspf.org URLs to openspf.net because openspf.org is unreachable
    indefinitely.
  * Change <http://www.ietf.org/rfc/….txt> URLs
    to <http://tools.ietf.org/html/…>.
  * META.yml: configure_requires: Module::Build 0.2805
  * META.yml: requires: Net::DNS 0.62 (was: 0.52) (Closes: rt.cpan.org #28545)
  * META.yml: Revert to flat version numbers for perl and Net::DNS::Resolver::
    Programmable build requirements to avoid Module::Build::Compat/Makefile.PL
    incompatibilities. (Closes: rt.cpan.org #53231)
  * Attempt to prevent a cascading failure in t/00.03-class-result.t that seems
    to happen under rare, unknown circumstances. (Closes: rt.cpan.org #39099)

  Debian:
  * Declare Debian source package format as 3.0.
  * Standards-Version: 3.9.2 (was: 3.8.3)
  * Bump debhelper compatibility level to 7 (was: 5) and simplify debian/rules
    using debhelper 7 features.
  * debian/control: Simplify depdendencies under the assumption that package
    will be installed on Debian Lenny (oldstable at the time of writing) or
    later (or the Ubuntu equivalent).
  * debian/watch: Use dist-based URL.
