DEVELOPER UPDATES

IronPDF Developer Update, October 2022

5 minutes with our developer team

I'm a developer, and I enjoy solving problems. Most of us do.

But, you shouldn't have to solve a problem when you use IronPDF. It should simply work.

The number #1 complaint we had from devs was "my platform is not supported!" - And to be fair, they had a point.

You shouldn't have to figure out a workaround with IronPDF (even if you've got the skills to do it), because a big reason to purchase our software is to make this particular step seamless.

We're now 48% more seamless according to our drop in support tickets. That's largely because of the increased compatibility of IronPDF. Learn more about IronPDF's compatibility improvements.

Compatibility improvements have happened over two years, and they're ongoing.

What's the latest?

The most impactful usability change this month's changelog details has been to paper size defaults. They're now accurate to 0.00001 millimeter, and they override existing CSS Stylesheet settings. That means no more hardcoded print defaults in file settings, and no more wasted time building workarounds.
