[ruby-core:85792] Ruby 2.6.0-preview1 Released

We are pleased to announce the release of Ruby 2.6.0-preview1.
Ruby 2.6.0-preview1 is the first preview toward Ruby 2.6.0.
This preview1 is released earlier than usual because it includes an
important new feature, JIT.
## JIT
Ruby 2.6 introduces an initial implementation of JIT (Just-in-time) compiler.
JIT compiler aims to improve performance of any Ruby program execution.
Unlike ordinary JIT compilers for other languages, Ruby's JIT compiler
does JIT compilation in a unique way, which prints C code to a disk
and spawns common C compiler process to generate native code.
See also: https://github.com/vnmakarov/ruby/tree/rtl_mjit_branch#mjit-organization
How to use: Just specify "--jit" in command line or $RUBYOPT
environment variable.
Specifying "--jit-verbose=1" allows to print basic information of
ongoing JIT compilation. See "ruby --help" for other options.
The main purpose of this JIT release is to provide a chance to check
if it works for your platform and to find out security risks before
the 2.6 release.
Currently JIT compiler is supported only when Ruby is built by gcc or
clang and the compiler is available on runtime. Otherwise you can't
use it for now.
As of 2.6.0-preview1, we're just preparing infrastructure for JIT and
very few optimizations are implemented.
You can measure some of potential improvements in micro benchmarks
with this release, but it is NOT ready for benchmarking final
performance of Ruby's JIT compiler, especially for larger programs
like Rails applications.
We're going to implement method iniling in JIT compiler, which is
expected to increase Ruby's performance in order of magnitude.
Also, we're planning to increase the supported platforms, and the next
plan is to support Visual Studio.
Stay tuned for the new age of Ruby's performance.
## New Features
* Add Random.bytes. [Feature #4938]
* Add Binding#source_location. [Feature #14230]
* This method returns the source location of binding, a 2-element
array of `__FILE__` and `__LINE__`. Traditionally, the same
information could be retrieved by `eval("[__FILE__, __LINE__]",
binding)`, but we are planning to change this behavior so that
`Kernel#eval` ignores binding's source location [Bug #4352]. So,
users should use this newly-introduced method instead of
`Kernel#eval`.
* Add :exception option to let Kernel.#system raise error instead of
returning false. [Feature #14386]
## Performance improvements
* Speedup `Proc#call` because we dont' need to care about `$SAFE` any more.
[Feature #14318]
With `lc_fizzbuzz` benchmark which uses `Proc#call` so many times we
can measure
x1.4 improvements [Bug #10212].
* Speedup `block.call` where `block` is passed block parameter. [Feature #14330]
Ruby 2.5 improves block passing performance. [Feature #14045]
Additionally, Ruby 2.6 improves the performance of passed block calling.
With micro-benchmark we can observe x2.6 improvemnt.
## Other notable changes since 2.5
* $SAFE is a process global state and we can set 0 again. [Feature #14250]
* Passing safe_level to ERB.new is deprecated. trim_mode and eoutvar
arguments are changed to keyword arguments. [Feature #14256]
* Merge RubyGems 2.7.6
