mold 2.30.0 is a maintenance release of the high-speed linker. It includes the following minor bug fixes:

• We have increased the version number from 2.4.1 to 2.30.0, even though this release contains only minor bug fixes. This change was made to prevent GNU libtool from mistaking mold 2.4.1 for GNU ld 2.4.1, which led it to incorrectly conclude that our linker was an outdated version of the GNU linker. Bumping up the version number to align with GNU ld may not be the most elegant solution, but it is a practical approach to resolve the compatibility issue with GNU libtool. (c7f6a91da512ef8a2634a1bef5d4ba82104659fe)
• Previously, mold may have inserted an unnecessary gap before the .bss section in an output file, thereby creating an extra segment for it. While not technically incorrect, it was certainly unnecessary. mold 2.30.0 eliminates this unnecessary on-disk gap for .bss. (c395da1c5414656e1b22f3e71a42ba17c51673a4)
• Previously, under rare circumstances, mold might fail with the "ConcurrentMap is full" error message if --gdb-index was used. This bug has been resolved. (c60d1d0877aeb713fc392d2e7c2396854cca0dbd)
• Previously, mold might generate an excessive number of "ignoring .llvm_addrsig section without sh_link" warnings. These warnings are now suppressed. (51f871f43b3f012a4367538f3bd831d701cb10ed)
• Sections with unknown section types are now reported as errors. (d21207cc79bb8f6074a21ff1b588d50ab7e5fa2f)
• [PPC32] A crash bug related to --gc-sections has been fixed. (8eae0a33b374862345a7293d4a85a491c309d82b)
