    **Version 1.6.15**

    This is a security update to the stable version 1.6 of Roundcube Webmail.
    It provides fixes to some regressions introduced in the previous release as well a recently reported
    security vulnerability:

    -    SVG Animate FUNCIRI Attribute Bypass  Remote Image Loading via fill/filter/stroke, reported by
    class_nzm.

    This version is considered stable and we recommend to update all productive installations of Roundcube
    1.6.x with it. Please do backup your data before updating!

    CHANGELOG

    -    Fix regression where mail search would fail on non-ascii search criteria (#10121)
    -    Fix regression where some data url images could get ignored/lost (#10128)
    -    Fix SVG Animate FUNCIRI Attribute Bypass  Remote Image Loading via fill/filter/stroke
