SeNioR-

what's the difference

Wonderful idea!

You guys are da BOMB!!

I wish there will be not only credit card. Something like this:
Acquire a free trial version Collect the data for future invoice Invoice is automatically generated when free trial is over The customer is free to pay or abandon Is it possible with the feature?

Hi Helen. You chose a very good CMS. Good luck!

We should all race @Adlago in a community speedtest 🚗

Great job guys: 

Thanks. Good job, team! 

Thanks for all your hard work and improvements in the upcoming release. I'm excited to see it in action! 🙂

A little addition: Just in case you'll change your mind about raster images in backgrounds, here is some SVG examples:
svg.7z (yes 3 backgrounds, sized just in 2 kb in compressed state).

We won’t quite make it this year but will have a public alpha and/or it installed here on our site in the next few days.

California  Beverly Hills or San Francisco

Cracow, Poland 🙂
Or US - Miami 🙂

There is no actual benefit in doing this.
Those additional prefixes are also there for a reason. They're maintained for backwards compatibility. 

Not quite. It looks like that plugin replaces the video with a screenshot until the user clicks it to load the video. Our built-in approach will always load the video, but only once the user has scrolled down far enough to see it.

Moscow. I love cars traffic 😋

This is really good news, I'd been hoping to see a performance-based release for some time as traditionally IPS does rate low in Page SpeedGTMetrix/Yslow tests and we've been waiting for some of these overdue improvements for quite some time. So huge thanks! 
Lazyloading should really help with Gallery in particular, I currently get a poor Pagespeed score of F42 on one of my sites.
Please consider adding to your to do list (if not already added):
Serve scaled images (current GTMetrix reports a score of F0 with a 1.2MiB 80% possible saving is possible on my Gallery index page) Where static content is uploaded to Amazon S3 and Cloudfront (it should be copied, not moved!), often there is missing header metadata such as cache-control, expires etc. Whilst investigating poor Cloudfront cache hit ratios of just 5%, I noticed this week an IPS uploaded .png image placed in my S3 bucket with a content-type of image/jpeg instead of image/png.  Leverage Browser Caching (you can't do anything about Amazon and Google external resources, but IPS could and should add more to improve caching of its static resources) Specify Image Dimensions - I get awful scores for this both on Gallery and Forums where images are missing width and height attributes. This happens particularly in grid view layout and where you upload an image attachment into forum description fields via AdminCP.  Remove query strings from urls - Have raised this several times, and keep getting told it's needed to allow cache busting, but the string token could be built into the actual filename/url itself. If CSS for example is later rebuilt, a new url is created and immediately browsers see the updated resource and recache it. All of the separate CSS and JS files should be grouped into one or two files, not like 10-12. Pages article images should have medium sized thumbnails available instead of just tiny thumbnails which look awful stretch to cover on 4K displays. The alternative is full-sized (in my case massive 1920x1080 images) which kill page loading times are are such overkill for article listing previews.  
 
 
 

This is absolutely no longer the recommended approach with HTTP/2 becoming mainstream, just FYI. Naturally there's always a balance, but I would recommend reading up some more on best ways to handle CSS/Javascript with HTTP/2 to learn more.

My site with minimal changes has a performance rating of 29  Invision was only 41 

This is great news! I was just looking for a way to speed up image loading and found this article.  I was also reading up on HTTP/2 so was happy to see this support added.
Not sure if I missed it but would love to see CSS and JS combined into one output file for each.
Maybe test the suite through web.dev to see what else can be optimized? Since google is the big one and released this tool https://web.dev/measure

@Mr 13 We've actually optimized all images in the suite too; the default coverphoto image is now ~280KB. Also, cover photos across the suite are indeed lazy loaded too.
@Joel R Yes there's a background task that will clean up the existing letter photos.
For developers, I wanted to add that our lazy loading utility is very flexible, so you can actually use it to lazy load whatever you want, and pretty finely control what happens (with preload, load and post-load callbacks). We hook into IntersectionObserver which is a new(ish) API in browsers that make it super efficient to check when an element comes into view. Of course, our regular content controllers already handle lazy loading images and videos in UGC for you, but if your apps have other areas where it'd be useful, you can do that quite easily 🙂 

I love, that default avatars be in SVG! Thanks IPS! ❤️

God bless the IPS team. Cannot wait for 4.4 now!
