Summary

This release fixes a number of bugs and enables running on macOS 26 (Tahoe).

Details

Runtime System

Ported various fixes from the development repository.

SML/NJ Library

Added a number of operations to the MONO_HASH_SET interface to make it more compatible with the ORD_SET interface.
Added LEB128 module, which implements packed encoding and decoding of integer and word types using the Little Endian Base 128 encoding.
moved the JSON structure from the JSON Library to the Util Library. This change was made to allow code to produce/consume JSON values without depending on the JSON library.

32-bit macOS issues

While the x86 installer for 110.99.9 works on macOs 10.14 Mojave, building from source requires some extra steps because the version of Xcode distributed for Mojave does not include a 32-bit SDK.

Another issue that you may encounter when building on macOs 10.14 Mojave is an error message for a shell script of the form

  /bin/sh: bad interpreter: Operation not permitted

This error arises because the com.apple.quarantine attribute is set on the shell script. To fix the problem, remove the attribute using the command

  xattr -d com.apple.quarantine shell-script

and resume the build.
