AI Bots Making the Web Worse

Tue, 11 Aug 2026 00:00:00 +0000

Like many other FLOSS projects running on the goodwill of others (thanks OSUOSL you’re awesome). Our web infrastructure is being hit relatively constantly by AI bots.

Despite being told via robots.txt not to they seem to want to traverse the entirety of the of the old mercurial and git repositories that we’ve left for historical reference. Special shout out to “Lightpanda/1.0” which seems to be sending GETs for URLs not even hosted by our infrastructure.

So in addition to the ban-hammer for “Lightpanda/1.0” I’ve had to turn off the web interface for the old repositories. This shouldn’t really affect anyone as the current source is on https://github.com/crosstool-ng/crosstool-ng/ and has been for some time.

Below is some semblance of the release notes:

An upgrade procedure for configurations created in the previous release of crosstool-NG has been introduced with this release.

MacOS is not officially supported in this release.

Support for Alpine Linux as a host is experimental and is known to break in many configurations (particularly, *-linux-gnu): GLIBC fails to compile on a host using MUSL C library when it tries to create some helper applications to run on the build machine.

CentOS 6 and 7, while still supported, are known to break with recent GDB releases as they require a modern C++ compiler. The G++ included in CentOS 6/7 distributions does not satisfy GDB requirements. Also, “Build and install locales” option in GLIBC cannot be used on CentOS 6/7 build machines: this option requires GLIBC to built for the build machine, and recent GLIBC releases fail to compile on CentOS 6/7.

Released 1.24.0-rc3

Sun, 17 Mar 2019 00:00:00 +0000

Get the 1.24.0-rc3 release as bz2 (PGP signature) (md5, sha1, sha512) or xz (PGP signature) (md5, sha1, sha512) .

Note the upgrade procedure introduced with this release.

Also note that support for Alpine Linux as a host is also experimental and will break in many configurations (particularly, *-linux-gnu).

With this release candidate, a limited set of samples builds on all configurations present in testing/docker/ except Alpine. I will restart the full test on Monday; hopefully in a week or so we’ll have 1.24.0 release out the door.
