Opera Software heeft de vierde technology preview van het Opera Linux browsertje aangekondigd. De browser bevindt zich volgens Opera Software nog steeds in alpha stadium, maar heeft de afgelopen maanden wel veel ontwikkelingen door gemaakt. Een compleet overzicht vind je op www.opera.com/linux:
Since the release of Tech Preview 3, we've cleaned up a huge number of bugs, we have also invented some new ones. Those which are most visible are generally related to forms, EcmaScript, and plugins. We're working very hard to make sure that these are handled as soon as possible. We've made a lot of performance enhancments, we've debugged many issues related to communications, and we've done a great deal of work on the user interface. There is a still a good way to go, we have a list of everything that has to be done to get you all the features we possibly can as fast as we can.
Here's what Opera for Linux Tech Preview 4 does so far :
- Renders HTML 3.2 and 4.0 Pages
- Executes most EcmaScript 1.1 (Ecma-262 v.3) programs
- Renders CSS 1 and 2 extensions
- Browses FTP Sites
- Handles cookies
- Supports HTTP 1.0 and 1.1
- Supports GIFS (though still very buggy, we're testing a new FAR MORE memory efficient version in house now)
- Displays PNG and JPEG
- Has an MDI window interface (SDI scheduled for 4.1 now)
- Hot list and bookmarks have improved nearly to perfection now
- Export and imports bookmarks and IE favorites lists
- Support for XML is working better now
- Proxy server support
- Communication through SSL and TLS (the certificates dialogs are functional but still need much work)
- HTTP Authorization now works (the dialog looks a little funny, but it's close)
- Asyncronous DNS without threading
- Support for browsing local files
- Preferences are now about 95% complete, still some left to go
- Support for plugins (found in /usr/lib/netscape/plugins) only Flash seems to work for the moment
- File transfer has been implemented, and now works (although you can stop a file yet)
- Screen refresh is nearly perfect scroll bars work 99.995% of the time
- Animated GIFS now work (yes even on pages with more than one of the same GIF)
- Image handling is much much faster now (at the expense of RAM, this will be fixed REALLY soon)
Here's what Opera for Linux doesn't do yet:
- Font handling is still off by a bit, we're working on it
- CSS is having problems with inline styles, most important issues are line ends
- Frames are nearly perfect, but still not there
- Plugins are offset by 2 pixels from the top and left
- Window resizing works nicely now
- Forms don't resize properly.
- Clicking back on a page with forms controls with the page anywhere but flush with the top puts the controls in the wrong place
- <TEXTAREA> field don't properly get deleted
- Opera crashes a bit more now than the previous version.
- Printing is temporarily removed in most places
Currently this version has only been tested on RedHat Linux 6.2; we'll be releasing versions regularly now with the progress updated. There are now also ports to other platforms working nearly as well as the RedHat Linux 6.2 version is. We're compiling on pretty much everything and making use of tools that are different between platforms to make Opera work as well as possible. Expect to start seeing Technology Previews on other platforms. Also expect to see packages for the different systems soon.
