[Misc #15347]
Posted by naruse on [Feature #14799] ******************************************************************************************************************************************************************************************************************************************** (Dec) [Misc #15347] [Misc #15347] We are pleased to announce the release of Ruby 2.7.0. (****************************** [Misc #15347] It introduces a number of new features and performance improvements, most notably: (******************************
************************** (Pattern Matching) REPL improvement
Separation of positional and keyword arguments (********************************** [] ************************ Pattern Matching [Experimental]
Pattern matching, a widely used feature in functional programming languages, is introduced as an experimental feature.
[Feature #14912] (******************************

It can traverse a given object and assign its value if it matches a pattern.

 REPL improvement (*************************************
****************************************** (irb) *********************************************, the bundled interactive environment (REPL; Read-Eval-Print-Loop), Now supports multi-line editing. It is powered by (reline) , areadline -compatible library implemented in pure Ruby. It also provides rdoc integration. In

irb you can display the reference for a given class, module, or method.[Feature #14683] ,[Feature #14787],[Feature #14918][Misc #15347] [Misc #15347] Besides, source lines shown by [:deprecated] ************************************ (Binding # irb) ********************************************* and inspect results for core-class objects are now colorized. (******************************(******************************************** (Compaction GC) 

This release introduces Compaction GC which can defragment a fragmented memory space. (******************************
Some multi-threaded Ruby programs may cause memory fragmentation, leading to high memory usage and degraded speed. (****************************** [Misc #15347] The [Feature #14799] ******************************** (GC.compact [:deprecated] ******************************** method is introduced for compacting the heap. This function compacts live objects in the heap so that fewer pages may be used, and the heap may be more CoW (copy-on-write) friendly.[Feature #15626] [Feature #15626] [Misc #15347]
Separation of positional and keyword arguments
Automatic conversion of keyword arguments and positional arguments is deprecated, and conversion will be removed in Ruby 3.[Feature #14183] [:deprecated] ************ [Feature #14799] [Misc #15347] See the article “ Separation of positional and keyword arguments in Ruby 3.0 (****************************************, in detail. . Only the changes are as follows. (******************************

When a method call passes a Hash at the last argument, and when it passes no keywords, and when the called method accepts keywords, a warning is emitted. To continue treating the hash as keywords, add a double splat operator to avoid the warning and ensure correct behavior in Ruby 3.
