Opera 12 security update
16th February saw the release of Opera 12.18 Many users of Opera 12 have disabled updates to stop the annoyance of the TLS reset and the reminders that a new version is available. Many users will also assume this new v12 update is just the offer of the Cropera version. Release 12.18 updates the security and certificate support (hooray !). It also addresses a security problem with the mail client. http://www.opera.com/blogs/security/2016/02/opera-12-and-opera-mail-security-update/
As it was a security related update I only thought to look in this section.
I should use the search function more I know.
