Con Ruby 2.1, `\"str\".freeze` está optimizado para reducir la \n+creación de nuevos objetos. Ruby 2.3 introduce un nuevo comentario _mágico_ y\n+una opción de línea de comando para especificar todas las literales de\n+cadena de texto.\n+Adicionalmente para depurado, usted puede obtener donde el objeto fue creado\n+cuando sucede el error `\"can't modify frozen String\"` con\n+--enable-frozen-string-literal-debug.\n+\n+[Safe navigation operator](https://bugs.ruby-lang.org/issues/11537)\n+([también conocido como el operador solitario](https://instagram.com/p/-M9l6mRPLR/)) `&.`, \n+el cuál existe en C#, Groovy y Swift, es presentado en ésta versión, para hacer \n+más sencillo el manejo de `nil` de la forma `obj&.foo`. `Array#dig` y `Hash#dig`\n+también se agregaron.\n+\n+[did_you_mean.gem is bundled](https://bugs.ruby-lang.org/issues/11252). \n+did_you_mean.gem muestra candidatos en las excepciones `NameError` y `NoMethodError` \n+con la finalidad de simplificar el depurado.\n+\n+[RubyVM::InstructionSequence#to_binary y .load_from_binary](https://bugs.ruby-lang.org/issues/11788) \n+ha sido introducida como una característica experimental. Con estas\n+características, es posible hacer un sistema ISeq (bytecode) de\n+pre-compilación.\n+\n+Ruby 2.3 introduce muchos arreglos para mejorar el rendimiento. Por ejemplo, \n+[Proc#call ha sido optimizado](https://bugs.ruby-lang.org/issues/11569),\n+[se reconsideró la estructura de datos para method entry](https://bugs.ruby-lang.org/issues/11278), \n+[se introdujo una nueva estructura de datos table](https://bugs.ruby-lang.org/issues/11420),\n+se mejoró a nivel de código máquina la creación de nuevos objetos y llamadas a\n+métodos, además de muchas más optimizaciones.\n+\n+Prueba y disfruta el programar con Ruby 2.3.0-preview2, y no olvides reportar\n+cualquier inconveniente.\n+\n+## Cambios notables desde la versión 2.2\n+\n+Visitar
