+
+Upstream has released link:https://gcc.gnu.org/gcc-13[GCC 13].
+As announced in the past status report, I plan to attempt an update of GCC_DEFAULT right from the first GCC 13 release, thus much of this quarter work has been in preparation of this.
+
+With the release of GCC 13.1 (first GCC 13 release: I remind that GCC counts minor version releases starting from 1), two new ports have been created in the ports tree:
+
+* package:lang/gcc13[], tracking GCC 13 releases;
+* package:lang/gcc14-devel[], tracking snapshots from the new GCC 14 upstream branch.
+
+==== The *-devel ports
+
+A few significant changes have been made on the *-devel ports, which will be forwarded to the production ports together with more changes (see below):
+
+* enable support for .init_array and .fini_array, which FreeBSD supports since commit gitref:83aa9cc00c2d83d05a0efe7a1496d8aab4a153bb[repository=src];
+
+* switch back to STANDARD_BOOTSTRAP on i386, amd64 and aarch64 as default option instead of LTO_BOOTSTRAP: LTO bootstrap produces too many failures on the package builders for those architectures.
+Users wanting to use LTO_BOOTSTRAP can still enable the option manually.
+
+==== The production ports
+
+Upstream has released GCC 13, for which the new port package:lang/gcc13[] has been created.
+GCC 11 and GCC 12 have been updated upstream and a new release of GCC 10 is planned.
+All corresponding ports now need to be updated.
+
+To ease the work of both ports maintainers and users, I plan to test and update together all the following changes:
+
+* updates of package:lang/gcc10[], package:lang/gcc11[], package:lang/gcc12[];
+* update of GCC_DEFAULT to 13;
+* enabling of .init_array and .fini_array on the production ports;
+* switching back from LTO_BOOTSTRAP to STANDARD_BOOTSTRAP on the production ports.
+
+This will provide the following advantages:
+
+* more testing with less exp-runs;
+* fewer builds for ports users.
