curl

Welcome to try out #curl 8.22.0-rc1 https://curl.se/rc/

Thanks for flying curl.

At times I'm thinking we should drop support for Windows. It's such a nightmare to support. #curl

On this day, twenty-six years ago, we shipped #curl 7.1. The first curl release that contained libcurl as a library for the transfer side of things, with the command line tool being the first user of that library.

https://curl.se/ch/7.1.html

To everyone‘s surprise, the added DoH test capabilities (and tests) in #curl exposes some edge case, unwanted behaviour in curl‘s DoH implementation.

Yes, even if your repository gets continuously scannd by the major AI models, you need test cases. Sorry!

Three working days after the #curl summer of bliss ended, we have reserved one more CVE Id. Now we have *two* fixed vulnerabilities to announce in sync with the pending next release coming on September 2.

It's actually a quite manageable reporting pace right now at this very moment. I suspect the reporters haven't yet properly figured out that flood gates have opened.

I'm pretty fine with that! 😎

On this date seven years ago, we did HTTP/3 with #curl for the first time:

It might be time for #curl performance/benchmark testing:

#curl

I would like us to move SSL session import/export out of experimental status for #curl before end of year 2026.

Welcome Ramesh Adhikari as #curl commit author 1503: https://github.com/curl/curl/pull/22449

I would like us to make an effort to move #curl's HTTPS-RR and ECH support out
of experimental mode before end of year 2026.

If you were looking for the minimum versions of the dependencies #curl and libcurl can use, they are now all listed on this brand new page on the site:

Join the fun and help us test "Apple fast UDP" with #curl. Using their undocumented functions...

https://github.com/curl/curl/pull/22417

If you're looking for something to help out with in the #curl project, here is an idea!

Enable one, some or all experimental features in your local build and use them for a while to see how they behave - and report all problems:

If you host a #curl download from before curl 7.20.0 (Feb 2010), we no longer link to it from the official curl download site, even if it was the last of its kind. Like IRIX, Tru64, UnixWare etc...

No #curl CVEs at all during July because of bliss. Highly recommended.

Out of the 100 million USD that has been donated through #GitHub sponsors, 0.0641% was given to #curl (64K USD since 2019)

Dear #network teachers, students and #hacker friends, I have a #browser based network simulator to enable learning #networking. Please have a look and tell me what do you think. Made for desktop or bigger screens.

https://howcomputer.works/netsim/ Everything is in the browser, and there is documentation.

The goal is to allow kids to start learning while their schools/systems are not big enough to be able to build lab networks. It has a small/minimal #curl implementation too. @bagder

glibc has this open bug to resolve link-local host names for AF_INET6 since 2012

https://sourceware.org/bugzilla/show_bug.cgi?id=14413

Now this causes problems to #curl, as it now does separate name resolves for IPv4 and IPv6 in order to start connecting once the first response is in. 😕

quicktipp #118: curl can be used to send emails with smtp

The current top story on the FT Magazine is pay-walled but features some mentions of #curl and yours truly... (the picture shows the start of it)
