Changelog

For a complete list of notable changes, check out the CHANGELOG.

Some highlights are:

• #898- we disabled state tracking by default in our generated LLVM code leading to a major speed improvement for uses that don't need it. It can be reenabled with the --track-state flag. This
• #897 - removes special casing of stdin, stdout, and stderr in WASI. This fixes issues like calling fd_close on these files. They may still be accessed from WasiFS with the stdout, stdout_mut, stdin, stdin_mut, stderr, and stderr_mut methods.
• #863 - fixed edge cases in max and min on floating point numbers in LLVM
