PERL5361DELTA(1perl)

💖 PERL5361DELTA 💖

okay bestie, you're reading perl5361delta from the Perl Programmers Reference Guide — the lil' glow-up diary for perl. grab a boba, we're going through it together 🧋✨

---

✨ NAME ✨

perl5361delta — literally what is new for perl v5.36.1 💅

---

🌸 DESCRIPTION 🌸

This doc spills the tea on the differences between the 5.36.0 release and the 5.36.1 release. tiny era, but an era nonetheless 🎀

heads up, if you're jumping up from something older like 5.34.0, go read perl5360delta first — that one covers everything between 5.34.0 and 5.36.0 🦋

---

💀 Incompatible Changes 💀

There are no changes intentionally incompatible with 5.36.0. iconic, stable, no chaos.

But if any incompatibilities do exist? they're bugs, fr fr, and we need you to submit a report. See "Reporting Bugs" below 👇

👑 Modules and Pragmata 👑

🎀 Updated Modules and Pragmata

• Module::CoreList got upgraded from version 5.20220520 to 5.20230423. glow up 💅

---

🔧 Configuration and Compilation 🔧

• Configure used to probe for the return type of malloc() and free() by testing whether declarations for those functions produced a function type mismatch with the implementation. On Solaris, with a C++ compiler, this check always failed, because Solaris instead imports malloc() and free() from std:: with using for C++ builds. And since the return types of malloc() and free() are well defined by the C standard... yeah, we just skip probing for them now. Configure command-line arguments and hints can still override these type in the unlikely case that is needed. no cap. [GH #20806](https://github.com/Perl/perl5/issues/20806) 🔥

---

🧪 Testing 🧪

Tests were added and changed to reflect the other additions and changes in this release. bestie the test suite stays fed 🍓

---

🩹 Selected Bug Fixes 🩹

• An eval() as the last statement in a regex code block could trigger an interpreter panic 😭, e.g.

/(?{ ...; eval {....}; })/

[GH #19680](https://github.com/Perl/perl5/issues/19680) — panic? not on our watch 💅

• An "eval EXPR" referring to a lexical sub defined in grandparent scope no longer produces an assertion failure. [GH #19857](https://github.com/Perl/perl5/issues/19857) 👑
• Writing to a magic variables associated with the selected output handle — $^, $~, $=, "$-" and $% — no longer crashes perl if the IO object has been cleared from the selected output handle. [GH #20733](https://github.com/Perl/perl5/issues/20733) 🫶
