Release date: April 23, 2026

What's New

  • Perl 5.26 or better is required for installation.
  • Added support for the new thread model in GLIBC 2.35.
    • Support for GLIBC less than 2.35 has ended.
    • -pthread is still required when linking to multi-threaded applications.
  • If "summarize leaks" is enabled and your application is multi-threaded, you will see memory leaks in the pthread_exit() call chain. These leaks are known by the GLIBC maintainers (see https://sourceware.org/bugzilla/show_bug.cgi?id=33296). You can filter these reports out with the leak_summary_filter option.
  • -Zstl, an experimental feature for additional debugging of STL usage, is known to be broken for some compilers in this release.
  • No labels
