 YJIT is a lightweight, minimalistic Ruby JIT built inside CRuby.
 It lazily compiles code using a Basic Block Versioning (BBV) architecture. The target use case is that of servers running
 Ruby on Rails, an area where MJIT has not yet managed to deliver speedups.

+YJIT is currently supported for macOS and Linux on x86-64 and arm64/aarch64 CPUs.
 This project is open source and falls under the same license as CRuby.

 ### Command-Line Options
 
 YJIT supports all command-line options supported by upstream CRuby, but also adds a few YJIT-specific options:
 
 - `--yjit`: enable YJIT (disabled by default)
-- `--yjit-call-threshold=N`: number of calls after which YJIT begins to compile a function (default 2)
+- `--yjit-call-threshold=N`: number of calls after which YJIT begins to compile a function (default 10)
 - `--yjit-exec-mem-size=N`: size of the executable memory block to allocate, in MiB (default 256 MiB)
 - `--yjit-stats`: produce statistics after the execution of a program (must compile with `cppflags=-DRUBY_DEBUG` to use this)
+- `--yjit-trace-exits`: produce a Marshal dump of backtraces from specific exits. Automatically enables `--yjit-stats` (must compile with `cppflags=-DRUBY_DEBUG` to use this)
 - `--yjit-max-versions=N`: maximum number of versions to generate per basic block (default 4)
 - `--yjit-greedy-versioning`: greedy versioning mode (disabled by default, may increase code size)
