# New Opera developer 40

• Hi @eng8989, you can add the command line switch at the end of the shortcut to the "launcher.exe", as follows:

"\path\to\the\launcher.exe" --disk-cache-size=<amount in bytes>.

• My Bitdefender Free Edition has detected three clearkeycmd files that appear to be associated with Opera Developer as Trojans and has quarantined them.

False positive.

• False positive.

Yes, but that info does not help get Opera updated. Can you contact BitDefender and inform them of the situation so they fix this? No way to "white list" those files from the client as far as I can tell.

• Same issue as codalyth ... for earlier version as well (39).

Also:

• not even opera.com loads in any version so far.
• these help pages need more facilities, e.g. image uploads etc.

Thanks Opera!

• OK, thanks. Similarly, HitmanPro detects three Opera Developer .exe files as Trojans. Not sure if it's the same as with Bitdefender, I'm not an expert on this, but I'll assume that it is.

Temporarily disable Bitdefender, update Opera and then enable it again.

Can you contact BitDefender and inform them of the situation so they fix this?

I could if i was a Bitdefender user and was getting those alerts.

• I gotta' say that Opera seems so much lighter and responsive than does Vivaldi or Chrome here. Lookin' very good!

• OK disabling BitDefender got the files DL'd without being blocked. But now I'm in a loop - version 40 files downloaded - click to relaunch. It relaunches at version 39. DL version 40 files again - click to relaunch. Relaunches at version 39, etc. etc. UGH.... Guess I'm stuck at 39.xxx

• anyway I like the Developer version x64 this time, I copied my stable data to it and make it stand alone and it stay awesome! Rock, HOO YEAH

• OK disabling BitDefender got the files DL'd without being blocked. But now I'm in a loop - version 40 files downloaded - click to relaunch. It relaunches at version 39. DL version 40 files again - click to relaunch. Relaunches at version 39, etc. etc. UGH.... Guess I'm stuck at 39.xxx

Run the installer, it should solve the problem.

It did for me (eventually). I have also now excluded it in from Bitdefender scanning, so I shouldn't see the file being disinfected time and time again. However, 40 seems to run OK after Bitdefender cleaned it (presumably quarantined), but I'm not sure what this dll actually does.

• New build - Opera developer 40.0.2273.0, the change log, and the announcement

"Today’s release brings good news for all those, who were unable to enter the YouTube full screen mode, when Windows DPI was set to more than 100%. The issue is fixed now with DNA-55464 – please update to the newest version of the Opera developer, and try for yourselves!

Several stability, and user interface fixes have also been applied, which should improve your browsing experience. Most of the easily noticed fixes are related to VPN, and personal news. Inquisitive users should also notice something interesting in the flags - to spice up your curiosity, I can only add that it is related to something you’ve been asking for quite some time. Happy discovering!

In things related, Chromium also has been updated, this time to the 53.0.2767.4 version.

Known issue: we are unable to release the experimental Windows x64 version today. We apologize for the inconvenience and would like to ask for a bit of patience."

\m/ :cheers:

• For the last two days I can't access any websites with the VPN enabled... I have the words 'unauthorized access' shown on the top left hand side of the browser window.
Any suggestions?

• New build - Opera developer 40.0.2280.0, the change log, and the announcement

"In today’s developer update, you will find the following changes and fixes:

##### Personal news enhancements

The personal news feature is being intensively developed at the moment. Various ideas are being tested and implemented to make this feature as useful as possible. Currently we’d like you to pay attention at the following highlights:

- More consistent layout in the list view and Top50:

- Improved recommendations: we have removed the generic ones in the sidebar and now, show only the relevant ones at the end of a news stream.

- We removed a slay of dead sources from the catalog and worked on the statistics to ensure you are getting really personalized streams.

##### Search popup

We are also introducing the search popup, which makes the daily routines easier for everyone. We have been inspired by mobile platforms, where context menus appear without any additional clicks. So, if you select a text, the popup will appear with the most useful functions – search or copy. Of course, you are in control of this feature and you can turn it off in the Browser / User Interface section of settings.

##### New default theme

The default theme appearing on the start page and internal pages, has also been changed. We hope you like it!

##### Other changes

There are various changes to VPN functionality – many of these will be transparent to the user. Also, quite a number of Mac fixes has been implemented. For details, please take look at the change log.

Known issues:

1. Unfortunately, the Windows x64 issue proved to be harder to fix than expected, so we don’t have Win x64 builds again. Sincerest apologies. We are working on that.

2. Mac users will notice display issues with the page title.

3. We’re aware that the search/copy popup is not DPI scaled."

\m/ :cheers:

• New build - Opera developer 40.0.2288.0, the change log, and the announcement

"Today’s Opera developer update contains two main functionality changes. One of these is already known but significantly changed while the other is quite new. Here they are:

##### New battery saver UI

We attempted to redesign the battery saver UI so that it can suit needs of both regular and experienced users. Experienced users will find additional power saving settings to tinker with in feature builds (behind a flag at the moment), while regular users will have immediate access to the power saving mode, with default settings, through visual hints. The hints show more info regarding the function, for instance we have added a counter which estimates how much battery time is left for the user:

##### Speed Dial suggestions

We are also releasing the very early preview of an easier way to add your most popular websites to your speed dials. At the moment, we experiment with the most popular websites and also investigate possibility how to make those suggestions more relevant. This feature will be developed for the next weeks, so your feedback is highly welcome.

Known issues:

I must admit I feel really embarrassed to have to announce that the x64 Windows builds are still not available. We are hoping for the best but myself, I cannot really do anything.

Also, OS X users won’t be able to use the Netflix service because of a problem with the Widevine plugin."

The Chromium has been updated to version 53.0.2774.3.

\m/ :cheers:

• I spent three hours trying to get Opera to stop crashing after the auto-update to 2288. I finally had to rollback to 2280 and pin it. My guess is that it is the LastPass extension, but after three hours of lost time, I have to get back to my REAL job...

• Apologies for what you've gone through. However, could you please try 2288 with a clean profile and see if it still crashes for you? Of course, back up your primary profile first. Thanks in advance.

• New build - Opera developer 40.0.2296.0, the change log, and the announcement

"As we approach midsummer in this area, we would like to offer a developer update which includes one feature that was frequently asked for. You may now realize it is…

The work on personal news is continued. This build comes with another set of changes and improvements. As an important addition, we also bring the first version of RSS support!

Even though the functionality is very limited at the moment, you can already take it for a spin. Just click on +Add sources button and paste URL into search field (for instance: https://www.nasa.gov/rss/dyn/breaking_news.rss). Once recognized as valid source, you can add it (in case it doesn’t work for you, please post the URL in comments).

Custom RSS can be read in both: timeline, and stacked view. However, the estimated reading time is not available for those sources.

The feature is pretty rough on the edges. But hey, this is what developer is for. We know there are the following issues, and they will get addressed in upcoming updates:

- Missing “Remove from my sources” button but there’s a workaround: Go to +Add sources paste the same URL and untick it.

- When combined with other sources, article age is not taken properly into account and timeline gets messed up.

Please let us know, what you think.

##### Chromecast

Maybe not as much expected as the RSS feature, but still very important – today, we are also offering Chromecast finally working in this developer version. Specifically, when you install the Google Cast extension from the store and have the special device attached to your display and operating in the same Wi-Fi network, the device should be detected and sending links should work.

##### Other changes

At last! We have fixed the Windows 64bit issue and today, we are offering the experimental version.

Known issue: the opera:about page sometimes freezes the browser."

The Chromium has been updated to version 53.0.2783.2.

• With this new version when VPN is on I get an "unauthorized access" message and many website pages won't load. With it off pages load normally. Suggestions?
