GCC 16 Release Series: Changes, New Features, and Fixes

From the announcement:

• C++20 by default: [...] N.B. C++20 modules support is still experimental and must be enabled by -fmodules.

• Several C++26 features have been implemented:
  • P2996R13, Reflection (PR120775, enabled by -std=c++26 -freflection)
  • P3394R4, Annotations for Reflection
  • P3293R3, Splicing a base class subobject
  • P3096R12, Function Parameter Reflection
  • P3491R3, define_static_{string,object,array} (PR120783)
  • P3560R2, Error Handling in Reflection
  • P1306R5, Expansion statements (PR120776)
  • P2900R14, Contracts (PR119061)
  • P2795R5, Erroneous behavior for uninitialized reads (PR114457)
  • [...]

• Improved experimental C++20 modules support:
  • New command line option --compile-std-module that conveniently builds the <bits/stdc++.h> header unit and the std and std.compat modules before compiling any source files explicitly specified on the command line.
  • Whenever the <bits/stdc++.h> header unit has been built, GCC now transparently translates an #include of any importable standard library header into an import of <bits/stdc++.h>.
  • Many reported bugs have been fixed, thanks to Nathaniel Shead.
  • [...]

Runtime Library (libstdc++)

• Improved experimental support for [...]
  • std::mdspan, thanks to Luc Grosheintz.

The annual global C++ developer survey is now open:

2026 Annual C++ Developer Survey "Lite"

Please share your feedback in this annual 10-minute survey to help inform C++ standardization and C++ tool vendors. This is the biggest opportunity we all have each year to make our voices heard and help improve our industry and community!

A summary of the results, including aggregated highlights of common answers in the write-in responses, will be posted publicly here on isocpp.org and shared with the C++ standardization committee participants and C++ tool vendors to help inform C++ evolution and tooling.

The survey closes in one week.

Thank you for participating and helping to inform our committee and community.

Qt Jenny 1.0 Released -- Rami Potinkara

By Ville Voutilainen | Dec 20, 2025 03:00 PM | Tags: None

Qt Jenny is a Java/Android JNI glue/proxy Qt code generator. You can find and get it from Maven Central. Qt Jenny is a fork of Jenny from LanderlYoung. The fork differs from the original one by supporting JNI call gluing with QJni - classes such as QJniObject. That brings the powers of Qt for Android and the magic of Android Java native APIs to Qt!

From the article:

Have you heard about Jenny? No, I do not mean, the girl next door, nor the Spinning Jenny that started the industrial revolution in England in the 17th century. This one is a modern information age revolution, a code generator, a cuter Jenny. Got your eyebrows raised? Are you a Qt developer? Perhaps you are mastering cross-platform development with Qt and deploying apps to Google Play? Read more below!

PVS-Studio 7.38 has been released. This version brings the new core for the C and C++ analyzer, the user annotation mechanism in the Java analyzer, enhanced taint analysis, and that's not all! See more details in this note.

PVS-Studio 7.38: new C++ analyzer core, user annotations in Java, enhanced taint analysis, and more

by Aleksandra Uvarova

From the article:

The C and C++ analyzer got a new core with completely redesigned components like a parser, a semantic analyzer, and a type system. The new core provides more accurate handling of template constructs and better parsing of the standard library and code based on modern C++ standards. During the extended testing period (EAP), the new core demonstrated stable performance across a wide range of real-world projects.
