Tags: 0.6.3-1
http://bugs.debian.org/228788
* New upstream version.
* Added patches:
  + [10_alsa_init_fix] New, from upstream CVS.
    Initialize direction variable when setting Alsa parameters.
  + [10_canvas_translation_fix] New, from upstream CVS.
    Do not translate tooltips twice in canvas popup.
  + [10_checkbox_fix] New, from upstream CVS.
    Use proper set/test methods on metronome checkboxes.
  + [10_html_doc_cleanup] New.
    Fix links and HTML errors in documentation.
  + [20_allow_system_timer] New.
    The new upstream version fails by default if the real-time clock
    could not be accessed (usually the case when not running suid-root).
    This patch reverts the old behaviour of falling back to the more
    inaccurate system timer.
* Updated patches:
  + [11_PIC_fixes_fixup] Rediffed.
* Removed patches:
  + [20_no_atomic_asm] Merged upstream.
* debian/compat: Splice out debhelper compatibility level from rules file.
* debian/control: Build-depend on latest jack release by default.
  Closes: #228788
* debian/control: Bump standards version.
* debian/control: Use auto-generated debconf dependency via misc:Depends.
* debian/control: Minor tweaks to the long description.
* debian/control: Tighten fluidsynth build dependency to sane version.
* debian/muse.doc-base: New. Register HTML documentation with doc-base.
* debian/templates: Tiny rewording, and typo fix.
* debian/templates, debian/po/*: Switch to po-debconf for translations.
