Ruby 2.4.0 25 Dec 2016
o Introduce hash table improvement (by Vladimir Makarov)
Improve the internal structure of hash table (st_table) by introducing open
addressing and an inclusion order array. This improvement has been discussed
with many people, especially with Yura Sokolov.
o Binding#irb: Start a REPL session similar to binding.pry
While you are debugging, you may often use p to see the value of
variables. With pry you can use binding.pry in your application to launch a
REPL and run any Ruby code. r56624 introduces binding.irb which behaves like
that with irb.
o Unify Fixnum and Bignum into Integer
Though ISO/IEC 30170:2012 doesn¡Çt specify details of the Integer class,
Ruby had two visible Integer classes: Fixnum and Bignum. Ruby 2.4 unifies
them into Integer. All C extensions which touch the Fixnum or Bignum class
need to be fixed.
See also the ticket and akr¡Çs slides.
o String supports Unicode case mappings
String/Symbol#upcase/downcase/swapcase/capitalize(!) now handle Unicode case
mappings instead of only ASCII case mappings.
o Performance improvements
Ruby 2.4 also contains the following performance improvements including
language changes:
* Array#max, Array#min
[x, y].max and [x, y].min are optimized to not create a temporary array
under certain conditions.
* Regexp#match?
Added Regexp#match?, which executes a regexp match without creating a back
reference object and changing $~ to reduce object allocation.
* Other performance improvements
- speed up instance variable access
o Debugging
* Thread#report_on_exception and Thread.report_on_exception
Ruby ignores exceptions in threads unless another thread explicitly joins
them. With report_on_exception = true, you can notice if a thread has died
due to an unhandled exception.
Send us feedback what should be the default for report_on_exception and
about report-on-GC, which shows a report when a thread is garbage
collected without join.
* Thread deadlock detection now shows threads with their backtrace and
dependency
Ruby has deadlock detection around waiting threads, but its report
doesn¡Çt include enough information for debugging. Ruby 2.4¡Çs deadlock
detection shows threads with their backtrace and dependent threads.
o Other notable changes since 2.3
* Support OpenSSL 1.1.0 (drop support for 0.9.7 or prior)
* ext/tk is now removed from stdlib Feature #8539
* XMLRPC is now removed from stdlib Feature #12160
See NEWS or commit logs for details.

- remove other crypto related "recommends"
- Switch from Module::Install to ExtUtils::MakeMaker
- avoids the hassle with Module::Install for Perl without "." in @INC

1.014 2016-12-18

drop "use" statements in PAR/Heavy.pm added in edf5f24d

always refer to the included LICENSE file
- generate hello.par in Makefile target "pure_all"
1.013 2016-11-27

- Build t/hello.par at "make" time
1.012 2016-11-25
- Guard against concurrent extraction attempts of zip into "inc"
- use a file lock to protect the extraction of the complete zip into "inc"
- _run_member_*(), _tempfile(), _dl_extract():
make the "persistent" filename only visible when the file
has been completely written
- Make build and test work if @INC does not include "."
- Upgrade to Module::Install 1.17
changes in sbcl-1.3.18 relative to sbcl-1.3.17:
* minor incompatible change: existing values of CFLAGS, ASFLAGS,
CPPFLAGS, and LINKFLAGS will be incorporated into C compiler
invocations when building from source.
* minor incompatible change: the result of WRITE-TO-STRING may be
a BASE-STRING if all characters written are of type BASE-CHAR.
* minor incompatible change: the broadcast stream with no output
streams is a singleton object. That object satisfies OPEN-STREAM-P
regardless of how many times CLOSE is invoked on it.
* enhancement: x86[-64] backends contain an experimental feature
which aids in demonstrating reachability of any object starting
from a tenured object or a thread stack by producing a proof
as a sequence of pointers to follow.
The file "tests/traceroot.test.sh" contains an example usage.
* enhancement: if the alien symbol "gc_coalesce_string_literals" is
set to 1 prior to SAVE-LISP-AND-DIE, then similar string constants
loaded from different fasl files may be collapsed to one object.
If the variable is set to 2, then additionally strings which are
STRING= in code resulting from COMPILE can be coalesced.
For instance, two functions returning the literal string "HI"
might return EQ strings after collapsing, which may be undesired
in a particular use. The flag pertains to gencgc only.
* enhancement: SXHASH values on pathnames are better distributed
* bug fix: MAKE-PATHNAME removes empty strings as components of a
directory, as is permitted: "Whenever a pathname is constructed
the components may be canonicalized if appropriate."
* optimization: various printer and FORMAT performance enhancements.
* bug fix: GET-FOREGROUND no longer fails in case all other interactive
threads exit (lp#1682671, reported by Syll)
* bug fix: RELEASE-FOREGROUND always removes the current thread from the
list of interactive threads. (lp#1682867, reported by Syll)
