* PPC64LE and SPARC64 are now supported as new targets. They haven't yet been as
    well tested as other targets, but they are already able to link mold itself on
    these platforms. (Note that PPC64LE is very unlikely to work on the most recent
    POWER10 machines as we didn't have a chance to test it due to a limited
    availability (POWER10 was released in 2021). If you can support us on this
    matter, please contact us. We also accept donations, so please consider
    supporting our project!)
  * RV32BE and RV64BE (32-bit and 64-bit big-endian RISC-V) are now supported as
    experimental targets. RISC-V is usually little-endian, but there exists a
    big-endian RISC-V as an extension. You can make gcc to emit code for big-endian
    RISC-V by passing -mbig-endian. mold can now link object files generated with
    that option.
  * --compress-debug-sections=zstd is now supported. This is an option to compress
    debug info embedded to an output file with Zstandard compression algorithm.
    Compared to the existing --compress-debug-sections=zlib, zstd is faster and
    gives a higher compression ratio. You probably can't start using zstd
    compression today though, because other tools such as gdb may not be able to
    read zstd-compressed debug info yet. But adding this option early makes mold
    future-proof. (ede7a5a)
  * mold no longer aligns loadable segments to page boundaries to reduce output file
    size. Previously, we allocated holes between loadable segments. The saving by
    this change is most visible for small programs. For example, a "hello world"
    program used to be ~18 KiB on x86-64. It's now 7.2 KiB. (2941d75)
  * Bug fixes and compatibility improvements
  * [RISCV] We optimized code so that the link speed for RISC-V is now comparable to
    the other targets. As an example, linking mold itself (~150 MiB in size) for
    RV64 used to take ~45 seconds on a simulated 16-core machine. It now takes only
    ~0.25 seconds. (3ab5489)
  * mold used to create more than one .rodata section under a certain condition.

* mold used to create more than one .rodata section under a certain condition.
It's not technically wrong but confused Valgrind. This issue has been resolved.
(25c7aee)
* [ARM32] Previously, mold failed to promote remaining undefined symbols to
dynamic symbols if symbols are undefined weak. That caused a link failure for
libxml (#660). This issue has been resolved. (72e26d9)
* mold didn't copy symbol types when creating symbol aliases for the --defsym
option. (8c7f31c)
* --compress-debug-sections=zlib-gnu has been removed. LLVM lld removed that
option too as there seems to be no usage of the flag.
- Enable ppc64le and use system zstd library as package dependency.
