Yesterday afternoon the Opera Mini servers were upgraded to version 4.19.752. This upgrade also includes the latest version of Opera Presto, our rendering engine.

  • Upgraded to Opera Presto 2.5 (see http://www.opera.com/docs/specs/presto25/ for changes, but be aware that not all of them apply to Opera Mini). This also reflects in an adjusted user agent string:
    "Opera/9.80 (J2ME/MIDP; Opera Mini/CLIENT_VERSION/SERVER_BUILD; U; LANGUAGE) Presto/2.5.25"
  • improved image handling
  • better handling of Korean and Japanese charsets
  • fixed a number of site issues
  • history navigation fixes


All Opera Mini users automatically benefit from the update.
