Presto-based applications[edit]

Who knows for sure Macromedia Dreamweaver MX uses the Presto engine? I haven't seen any official comment regarding this. Also, testing the latest Macromedia Dreamweaver 8 on my heavy CSS-only layout reveals Dreamweaver8 to not being able to properly render the page (as Opera 7 and 8 do). Also, if you test Adobe CS 2 you will clearly see many Opera-tic render bugs while editing CSS-layout, and the right-click context menu is the Opera one :).

The only reason to believe Dreamweaver uses the Presto engine is ... the zoom feature and that it renders CSS much better than IE (yet not as good as Presto, nor Gecko).

Isn't it possible that Dreamweaver uses its own render engine? --

On my Mac, Dreamweaver MX installed a (iirc OS 9 version of) Opera. See [1], which says the companies were working together on integrating Opera into Macromedia products, for more verification. -- k 04:01, 27 September 2005 (UTC)
That's for Macromedia Dreamweaver on Mac. How about Windows? I'm almost sure Presto is not used on the Windows version of Dreamweaver. Robodesign 19:28, 30 September 2005 (UTC)
I think you're correct. I'll change the article to reflect this -- k 21:31, 19 November 2005 (UTC)

Presto in CS3?[edit]

Could someone please confirm that Presto is still being used in Adobe Creative Suite 3? Articles that need updating are Opera (web browser), Presto (layout engine), and Adobe Creative Suite. And please put your reference in those articles, thank you. Samsara noadmin (talk) 12:17, 12 January 2008 (UTC)


What programming language is Presto written in? Seems important, does anybody know? Thanks (talk) 14:12, 15 March 2009 (UTC)

Their job advertisements have always asked for C++, so that is probably the answer. Reference: [2] dramatic (talk) 22:06, 15 March 2009 (UTC)

Add Opera Mini to History and development[edit]

I'd like to see Opera Mini added to the History and development section to show how the Presto engine is used in production. I would do try and add this myself, but I don't really know enough about this subject and I don't have the time right now. Thanks. --Hm2k (talk) 17:17, 21 September 2009 (UTC)

Last version with Presto[edit]

The phrase "remained in use until Opera 12.14" strongly suggests that 12.14 was the last version of Opera using Presto. Yet 12.15 appears to use Presto as well. Although I can't find a source which verifies it, the User-Agent includes "Presto/2.12.388" (and does not include WebKit) and neither the changelog nor the release announcement makes mention of any changes to the layout engine. I'm also not sure the cited source supports the claim that 12.14 is the last version with Presto. Thoughts? -- Kevinoid (talk) 14:34, 4 April 2013 (UTC)

Ex-Presto developer here. Yes, all 12.xx versions of Opera definitely use Presto. Currently, only Opera version 14 for Android (out in beta) and desktop (no public release yet) use Chromium, and we're skipping the lucky number 13. The statement is partly true, in that we started phasing out Presto after 12.14, but the implication that 12.14 is the last to use Presto is misleading. (A really horrible security bug, for instance, could prompt another minor release years from now.)
Documenting this precisely with verifiable sources is slightly hard, but you're right that the current, incorrect statement isn't sufficiently documented by the blog post either. So IMO it can be corrected without making things worse from a citation POV. I don't think you'll ever find any official statement like "12.15 is the last Presto", so it's better to say something like "the 12.1x series is the last to use Presto" or refer to version 14 like I did above.
I feel quite disemboldened by WP:PSCOI, and the writing lobes of my brain aren't with me today, so please edit the article for me to express this.

I see the sourcing challenge. The source in this case does not actually support that Presto was "phased out" but neither was a source offered that confirmed it was still in use, so the article now only says that Opera began using Webkit and V8. without specifying what happened to Presto. CorporateM (Talk) 23:26, 30 June 2013 (UTC)
Hi Mr. Storset, nice to see you write here in person. I guess you still are one of the good old Opera guys who propelled forward the original project, and not what it has become of it now. There was a great article having one of your bosses(?) speak up about the demise of Opera ( ). Unfortunately, I must say the current mentioning of Presto being used until version 15 is plainly wrong. First V15 betas were the FIRST versions ever to be released WITHOUT Presto, so I hope this'll be still corrected sensibly later. -andy (talk) 18:26, 22 January 2016 (UTC)

what is "Core" ?[edit]

「Opera versions based on the Core fork of Presto, Opera 7.0 through 9.27, used the Linear B engine」 「The Futhark engine is used in some versions on the Core 2 fork of Presto, namely Opera 9.5 to Opera 10.10.」

what is the "Core" and "Core 2" ? thanks摩茲拉 (talk) 11:56, 12 February 2016 (UTC)
