[pmg-devel] [PATCH pmg-api v2 1/2] utils: allow specifying plain and/or html for finalize_report()

[Christoph Heiss <c.heiss@proxmox.com>]

To support both plain-text and HTML emails when sending reports,
PMG::Utils::finalize_report() first needs a small adaption to allow
specifying either only an HTML template or both.
