[php-maint] PHP 5 to PHP 7.0 transition and change of PHP packaging to allow coinstallable versions

[Ondřej Surý]

You mean like the list in NEWS.Debian?

php7.0 (7.0.3-6) unstable; urgency=medium

  * Several extensions have been split into separate extension packages:
   - php-dba - Database (dbm-style) Abstraction Layer
   - php-mbstring - Multibyte String
   - php-soap - SOAP
   - php-xml - DOM, SimpleXML, WDDX, XML, XMLReader and XMLWriter
   - php-zip - Zip
  * The new packages are not installed automatically, so you will need
  to
    install them by hand, if you use the functions in those modules.
  * Most modules that have been builtin before are now included in
    php7.0-common package and they are enabled by default for your
    convenience.  You can disable unneede modules via phpdismod tool.
