Changelog

New features:

• New TruffleRuby::ConcurrentMap data structure for use in concurrent-ruby (#2339, @wildmaples).
  

Bug fixes:

• Fix of different values of self in different scopes.
  
• Truffle::POSIX.select was being redefined repeatedly (#2332).
  
• Fix the --backtraces-raise and --backtraces-rescue options in JVM mode (#2335).
  
• Fix File.{atime, mtime, ctime} to include nanoseconds (#2337).
  
• Fix Array#[a, b] = "frozen string literal".freeze (#2355).
  
• rb_funcall() now releases the C-extension lock (similar to MRI).
  
• Fix rb_str_modify_expand to preserve existing bytes (#2392).
  
• Fix Marshal.load of multiple Symbols with an explicit encoding (#1624).
  
• Fix String#scrub when replacement is frozen (#2398, @LillianZ).
  

Compatibility:

• Updated to Ruby 2.7.3. The resolv stdlib was not updated (resolv in 2.7.3 has bugs).
  
• Make interpolated strings frozen for compatibility with Ruby 2.7 (#2304, @kirs).
  
• require 'socket' now also requires 'io/wait' like CRuby (#2326).
  
• Support precision when formatting strings (#2281, @kirs).
  
• Make rpartition compatible with Ruby 2.7 (#2320, @gogainda).
  
• Include the type name in exception messages from rb_check_type (#2307).
  
• Fix Hash#rehash to remove duplicate keys after modifications (#2266, @MattAlp)
  
• Only fail rb_check_type for typed data, not wrapped untyped structs (#2331).
  
• Decide the visibility in Module#define_method based on self and the default definee (#2334).
  
• Configure mandir value in RbConfig::CONFIG and RbConfig::MAKEFILE_CONFIG (#2315).
  
• TruffleRuby now supports the Truffle polyglot Hash interop API.
  
• Implement Fiber#raise (#2338).
  
• Update File.basename to return new String instances (#2343).
  
• Allow Fiber#raise after Fiber#transfer like Ruby 3.0 (#2342).
  
• Fix ObjectSpace._id2ref for Symbols and frozen String literals (#2358).
  
• Implemented Enumerator::Lazy#filter_map (#2356).
  
• Fix LLVM toolchain issue on macOS 10.13 (#2352, oracle/graal#3383).
  
• Implement IO#set_encoding_by_bom (#2372, pawandubey).
  
• Implemented Enumerator::Lazy#with_index (#2356).
  
• Implement rb_backref_set.
  
• Fix Float#<=> when comparing Infinity to other #infinite? values.
  
• Implement date library as a C extension to improve compatibility (#2344).
  
• Update rb_str_modify and rb_str_modify_expand to raise a FrozenError when given a frozen string (#2392).
  

Performance:

• Make #dig iterative to make it faster and compile better for calls with 3+ arguments (#2301, @chrisseaton, @jantnovi).
  
• Make Struct#dig faster in interpreter by avoiding exceptions (#2306, @kirs).
  
• Reduce the number of AST nodes created for methods and blocks (#2261).
  
• Fiber-local variables are much faster now by using less synchronization.
  
• Improved the performance of the exceptional case of String#chr (#2318, @chrisseaton).
  
• Improved the performance of IO#read_nonblock when no data is available to be read.
  
• TruffleSafepoint is now used instead of custom logic, which no longer invalidates JITed code for guest safepoints (e.g., Thread#{backtrace,raise,kill}, ObjectSpace, etc)
  
• Significantly improved performance of Time#strftime for common formats (#2361, @wildmaples, @chrisseaton).
  
• Faster solution for lazy integer length (#2365, @lemire, @chrisseaton).
  
• Speedup rb_funcallv*() by directly unwrapping the C arguments array instead of going through a Ruby Array (#2089).
  

Changes:

• rb_iterate() (deprecated since 1.9) no longer magically passes the block to rb_funcall(), use rb_block_call() instead.
  

Security:

• Updated to Ruby 2.7.3 to fix CVE-2021-28965 and CVE-2021-28966.
