    Returns a copy of str with the characters in from_str replaced by the
+corresponding characters in to_str.  If to_str is shorter than from_str,
+it is padded with its last character in order to maintain the
+correspondence.

    Both strings may use the c1-c2 notation to denote ranges of characters,
+and from_str may start with a ^, which denotes all characters except
+those listed.
    
+
+
    “hello”.tr(‘a-y’, ‘b-z’)    #=> “ifmmp”
+ “hello”.tr(‘^aeiou’, ‘’)   #=> “e**o”
    
+
+
    The backslash character \ can be used to escape ^ or - and is otherwise
+ignored unless it appears at the end of a range or the end of the
+from_str or to_str:
    
+
+
    “hello^world”.tr(“\^aeiou”, “”) #=> “hll*wrld”
+ “hello-world”.tr(“a\-eo”, “”)   #=> “hll*wrld”
    
+
+
    “hello\r\nworld”.tr(“\r”, “”)   #=> “hello\nworld”
+ “hello\r\nworld”.tr(“\r”, “”)  #=> “hello\r\nwold”
+ “hello\r\nworld”.tr(“\\r”, “”) #=> “hello\nworld”

    Note: conversion is effective only in ASCII region.

+# mruby 2.1.0
+
+We are proudly announcing the stable release of mruby 2.0 series - [mruby 2.1.0](https://github.com/mruby/mruby/releases/tag/2.1.0).  
+The [mruby 2.1.0](https://github.com/mruby/mruby/releases/tag/2.1.0) has been enhanced with compatibility with Ruby 2 series, and some new features of Ruby 2.7 have been added.
+
+---
+
+# New Features
+
+## Core Language Features
+
+- Suffix support (`Rational` and `Complex` literals) (#4125)
+
+## Core Libraries
+
+### Ruby 2.7 features
+
+- Add `Array#intersection` method which returns a new array containing elements common to both arrays. (mrbgems/mruby-array-ext)
+- Add `Enumerable#filter_map` method which is a short hand for `filter` + `map` in a single call. (mrbgems/mruby-enum-ext)
+- Add `Enumerable#tally` method which group and count elements of the collection. (mrbgems/mruby-enum-ext)
+- Add `Enumerator.produce` method which creates an infinite enumerator from any block. (mrbgems/mruby-enumerator)
+- Add `UnboundMethod#bind_call` method which call a method that overridden without allocation of intermediate Method object. (mruby-method)
+- `Module#name`, `true#to_s`, `false#to_s` return a frozen string. The returned string is always the same object.
+
+### Ruby 2.6 features
+
+- Add `Array#difference` method:  
+`Array#difference` returns a new array that is a copy of the original array, removing any items that also appear in other_ary. (mrbgems/mruby-array-ext)
+
+### New Libraries
+
+- Add `mrbgems/mruby-rational`:  
+[dyama/mruby-rational](https://github.com/dyama/mruby-rational) has been included into the core library, and rational numbers like `1/3` can be handled.
+- Add `mrbgems/mruby-complex`:  
+[pbosetti/mruby-complex](https://github.com/pbosetti/mruby-complex) has been included into the core library to handle complex numbers.
+
+### New C APIs
+
+#### Macros for checking object type

+### New test method (mrbtest)
+
+```ruby
+assert_match(pattern, str, msg=nil)
+assert_not_match(pattern, str, msg=nil)
+assert_raise_with_message(exc, exp_msg, msg = nil, &block

+assert_not_nil(target, msg)
+```
+
+## Tools
+
+### Interactive mruby (mirb)
+
+- As with `irb` in Ruby, a local variable `_` is added to store the last result.
+
+---
+# Update Features
+
+## mruby core
+
+- Allow newlines and comments between method calls. (4296c77e)
+- Support `&.` at the beginning of the line (4124047c)
+
+## Build system
+
+- Support lock file  
+It is now possible to fix mruby and mrbgems versions in products that use mruby.
+- Rename MRB_USE_ETEXT_EDATA to MRB_USE_LINK_TIME_RO_DATA_P and support lld linked programs (#4716)
+
+## C APIs
+
+### mruby core
+
+- Keyword arguments can be obtained with `mrb_get_args` using the format string `:`.
+- `mrb_parser_dump` supports displaying `NODE_DSYM`, `NODE_WORDS`, `NODE_SYMBOLS` and `NODE_LITERAL_DELIM`.
+- Raise `ArgumentError` by `aspec` check. (30f37872)
+
+### src/error.c
+
+- Add new specifiers/modifiers to format string of `mrb_vfromat()` (#4608)
+
+## mrbtest
+
+- Nested `assert` for mrbtest (#4540)
+
+---
+# Compatibility
+
+## mruby core
+
+- Pad leading zero to month and day in `MRUBY_RELEASE_DATE` (#4353)
+
+## Core Libraries
+
+- Add `Class#new(*args, &block)` method.
+- Add optional argument to `Module#class_variables`.
+- Add constants for floating point number. (`RADIX`, `MANT_DIG`, `EPSILON`, `DIG`, `MIN_EXP`, `MIN`, `MIN_10_EXP`, `MAX_EXP`, `MAX`, `MAX_10_EXP`)
+- Removed `$1`..`$9` from `Kernel#global_variables`.
+- String#unpack/Array#pack does support base64 directive (`m`).
+- Add encoding argument to `Integral#chr` (#4593)
+- Fixed `length` for IO should be in bytes, not in characters (8c90b5fc)
+
+---
+# Breaking Changes
+
+There are three major breaking changes from mruby 2.0.1.
+
+## Changed methods
+
+- Move `Array#append` and `Array#prepend` from core to `mrbgems/mruby-ary-ext`.
+- Move `Numeric#div` from `mrbgems/mruby-numeric-ext` to the core.
+- Move `Integral#zero?`, `Integral#nonzero?`, `Integral#positive?` and `Integral#negative)?` to `Numeric` class.
+- Move `Numeric#__coerce_step_counter` to `Integral` class.
+- Move `Kernel#instance_exec`, `Kernel#equal?` and `Kernel#instance_eval` to `BasicObject` class.
+- Move `NilClass#to_h` to `mrbgems/mruby-object-ext` from `mrbgems/mruby-enum-ext`
+- Move `String#getbyte`, `String#setbyte` and `String#byteslice` to the core. (#4696)
+- Remove `Kernel#global_variables` from core. This method is defined in `mrbgems/mruby-metaprog`.
+- Integrate `Integral#chr` (`Fixnum#chr`) to `mrbgems/mruby-string-ext`.
+- Remove `String#=~` and `String#match` that requires `Regexp` (fd37bc53)
+- `Symbol#to_s` return a frozen string. The returned string is always the same object. This feature will be reverted next mruby, because which reverted from Ruby 2.7.
+- Explicit `.0` is removed from result of `Float#to_s` and `Float#inspect`. (9d08025b)
+
+## Change C APIs
+
+- Rename symbol-to-string functions. (#4684)  
+  - `mrb_sym2name()` -> `mrb_sym_name()`
+  - `mrb_sym2name_len()` -> `mrb_sym_name_len()`
+  - `mrb_sym2str()` -> `mrb_sym_str()`
+
+## Remove C APIs
+
+- Functions to remove `MRB_API` from definitions (referenced from within `libmruby`):  
+`mrb_instance_new()`, `mrb_vm_define_class()`, `mrb_vm_define_module()`
+- `struct RIstruct` is renamed to `struct RIStruct` (e41f1574)
+* Remove `mrb_fixnum_plus()`, `mrb_fixnum_minus()`, `mrb_fixnum_mul()`, and `mrb_num_div()`. Use `mrb_num_plus()`, `mrb_num_minus()`, `mrb_num_mul()` instead.
+- Remove a member `ary` of `struct RString`. `struct RStringEmbed` is used for String embedding. (#4646)
+
+## mruby core
+
+- Remove global variable `$/`. The current Ruby policy do not encourage Perl-ish global variables.
+- Remove `MRB_TT_HAS_BASIC` macro. (#4728)
+- Remove members `flags` and `mems` of `struct mrb_state`. (0c5f26e0 and #4470)
+
+## Configuration
+
+- Remove `MRB_METHOD_TABLE_INLINE` and `MRB_NO_INIT_ARRAY_START`. (2256bb07 and #4716)
+- `MRB_USE_ETEXT_EDATA` is deprecated (warned and ignored). instead, use `MRB_USE_LINK_TIME_RO_DATA_P`. (#4716)
+
+## mruby binary (MRB)
+
+- Remove "LINE" section reader. (#4455)
+
+---
+# Major bug fixes
+
+- `SystemStackError` is raised from `String#=~`. (#4363)
+- Null pointer dereference in ecall. (#4370)
+- mismatched shift functions. (#4380)
+- Compilation error with "MRB_ARY_EMBED_LEN_MAX" in "array.h". (#4382)
+- Fixed a bug in recursive `mrb_top_run` calls; fix (#4384)
+- Unexpected error: `Can't get cfunc env from non-cfunc proc.` (#4389)
+- build error on master by MRB_WITHOUT_FLOAT. (#4478)
+- Null pointer dereference in mrb_str_cat_str. (#4504)
+- Some comments do not increment lineno on context. (#4513)
+- Null pointer dereference in mrb_check_frozen. (#4519)
+- Invalid read in mrb_class. (#4534)
+- Array#inspect recurses too much for self-referential arrays. (#4552)
+- Infinite loop in Integer#step when both args are INFINITY. (#4555)
+- Float#round hangs for large ndigits. (#4566)
+- Cannot call `Fiber.yield` in method. (#4567)
+- Reference to top-level variable in top-level block is broken. (#4581)
+- Bugs with mutually recursive Array and Hash. (#4582)
+- `mrb_gc_unregister()` may access freed memory. (#4618)
+- memcpy-param-overlap in str_replace_partial. (#4627)
+- Symbol#inspect does not handle Unicode characters. (#4678)

      call-seq:
+   Enumerator.produce(initial = nil) { |val| } -> enumerator
      
+
+
      Creates an infinite enumerator from any block, just called over and
+over.  Result of the previous iteration is passed to the next one.
+If +initial+ is provided, it is passed to the first iteration, and
+becomes the first element of the enumerator; if it is not provided,
+first iteration receives +nil+, and its result becomes first
+element of the iterator.
      
+
+
      Raising StopIteration from the block stops an iteration.
      
+
+
      Examples of usage:
      
+
+
      Enumerator.produce(1, &:succ)   # => enumerator of 1, 2, 3, 4, ….
      
+

      Equality—At the Object level, == returns
-true only if obj and other are the
-same object. Typically, this method is overridden in descendant
-classes to provide class-specific meaning.
      
-
-
      Unlike ==, the equal? method should never be
-overridden by subclasses: it is used to determine object identity
-(that is, a.equal?(b) iff a is the same
-object as b).
      
-
-
      The eql? method returns true if
-obj and anObject have the same value. Used by
-Hash to test members for equality.  For objects of
-class Object, eql? is synonymous with
-==. Subclasses normally continue this tradition, but
-there are exceptions. Numeric types, for example,
-perform type conversion across ==, but not across
-eql?, so:
      
-
-
      1 == 1.0     #=> true
-   1.eql? 1.0   #=> false

      Byte Reference—If passed a single Integer, returns a
+substring of one byte at that position. If passed two Integer
+objects, returns a substring starting at the offset given by the first, and
+a length given by the second. If given a Range, a substring containing
+bytes at offsets given by the range is returned. In all three cases, if
+an offset is negative, it is counted from the end of str. Returns
+nil if the initial offset falls outside the string, the length
+is negative, or the beginning of the range is greater than the end.
+The encoding of the resulted string keeps original encoding.

+
+# mruby 3.0.0
+
+We are announcing the first stable release of mruby 3.0 series - [mruby 3.0.0](https://github.com/mruby/mruby/releases/tag/3.0.0).
+
+With mruby 3.0, the memory used of the mruby VM has been significantly reduced, and we have succeeded in significantly saving memory.
+Previous versions required several hundred KB of RAM, but mruby 3.0 can launch an application with about 100 KB of RAM.
+
+Describes the new features and changes in mruby 3.0.  
+The main changes in mruby 3.0 are also described in [doc/mruby3.md](https://github.com/mruby/mruby/blob/master/doc/mruby3.md).
+
+---
+
+# New Features
+
+## Core Language Features
+
+- Implement endless-def. [Ruby:Feature#16746](https://bugs.ruby-lang.org/issues/16746)
+- Replace `R-assignment` by `single-line pattern matching`. [Ruby:Feature#15921](https://bugs.ruby-lang.org/issues/15921)
+- Support squiggly heredocs. [#5246](https://github.com/mruby/mruby/pull/5246)
+
+## Features for mruby Developer
+
+- Add new C APIs
+  - `mrbc_cleanup_local_variables()` - Clean up local variables on mrbc_context. [#4931](https://github.com/mruby/mruby/pull/4931)
+  - Add functions that take symbols as arguments.
+    - `mrb_define_singleton_method_id()`
+    - `mrb_define_class_method_id()`
+    - `mrb_define_module_function_id()`
+    - `mrb_undef_method_id()`
+    - `mrb_undef_class_method_id()`
+    - `mrb_define_const_id()`
+    - `mrb_funcall_id()`
+  - Add functions for symbol checking that return mrb_sym value.
+    - `mrb_intern_check()`
+    - `mrb_intern_check_cstr()`
+    - `mrb_intern_check_str()`
+  - `mrb_fiber_resume()` - Allow context switch from C module.
+
+---
+
+# Update Features
+
+## Reduce memory usage
+
+- Preallocate Symbols  
+  The mruby 3.0 can now significantly reduce RAM usage by allocating symbols to static memory area at compile time. See [doc/guides/symbol.md](https://github.com/mruby/mruby/blob/master/doc/guides/symbol.md) for more information.
+- Reduce memory usage of Hash objects. [f2d8db39](https://github.com/mruby/mruby/commit/f2d8db39)
+- Reduce memory usage when calling methods. [#5272](https://github.com/mruby/mruby/pull/5272)
+
+## Updated build process
+
+The old build configuration file `build_config.rb` has been reconfigured to a file in the `build_config` directory.  
+For example, the following typical build configuration is available.
+
+- `default`: the default configuration
+- `host-gprof`: compiles with `gprof` for performance tuning
+- `host-m32`: compiles in gcc 32bit mode on 64bit platforms
+- `boxing`: compiles all three boxing options
+- `clang-asan`: compiles with clang's Address Sanitizer
+
+You can specify the mruby build configuration by building mruby with the `rake` build, specifying the build configuration file in the environment variable `MRUBY_CONFIG`.
+
+## Core Libraries
+
+- Add new libraries.
+  - `mruby-catch` - Support `Kernel.#catch` and `Kernel.#throw`. [7eaaee54](https://github.com/mruby/mruby/commit/7eaaee54)
+  - `mruby-os-memsize` - Support `ObjectSpace.memsize_of` and `ObjectSpace.memsize_of_all`. [#5032](https://github.com/mruby/mruby/pull/5032) [#5040](https://github.com/mruby/mruby/pull/5040) [#5041](https://github.com/mruby/mruby/pull/5041)
+- Add `Array.new([])` initialization. (mruby-array)
+- Add `Hash#except` (mruby-hash-ext)
+- Update `IO#popen` to use keyword arguments. (mruby-io)
+- Make `Module#include` and `Module#prepend` behave like Ruby 3.0. [3972df57](https://github.com/mruby/mruby/commit/3972df57)
+
+## Tools
+
+- Allow to mixed and specify `*.rb` and `*.mrb` in `mruby` interpreter. [a045b6b8](https://github.com/mruby/mruby/commit/a045b6b8)
+- Add `irep` C struct dump from `mrbc` with `-S` option.
+
+## Features for mruby Developer
+
+- Add new specifier `c` to `mrb_get_args()` for receive Class/Module.
+
+---
+
+# Breaking Changes
+
+## mruby VM and bytecode
+
+Due to improvements in the binary format, mruby binaries are no longer backward compatible. 
+To run the mruby binaries on mruby 3.0, recompile with the mruby 3.0 `mrbc`.
+
+- Upgrade mruby VM version `RITE_VM_VER` to `0300` (means mruby 3.0).
+- Upgrade mruby binary version `RITE_BINARY_FORMAT_VER` to `0200`.
+
+## Recognize Integer system
+
+`Integer` has been changed to a specification similar to CRuby.
+
+- Integrate `Finxnum` and `Integer`.
+- Remove `Integral`.
+- `int / int -> int`
+- Add APIs for `Integer`.  APIs for`Fixnum` (`mrb_fixnum_xxx()`) is also left for compatibility.
+  - `mrb_fixnum()` -> `mrb_integer()`
+  - `mrb_fixnum_value()` -> `mrb_int_value()`
+  - `mrb_fixnum_p()` -> `mrb_integer_p()`
+
+---
+
+# Major bug fixes
+
+- Fix take over file scope variables with `mruby` and `mirb` command. [#4933](https://github.com/mruby/mruby/issues/4933)
+- Fix performing `block_given?` from inside an orphan block always returns false. [#5039](https://github.com/mruby/mruby/issues/5039)
+- Fix segmentation fault in Mruby interpreter making it crash [#5046](https://github.com/mruby/mruby/issues/5046)
+- Fix splat operator to frozen Array raises FrozenError. [#5067](https://github.com/mruby/mruby/issues/5067)
+- Fix wrong behavior of File.extname when the filename starts or ends with a period. (mruby-io) [#5077](https://github.com/mruby/mruby/issues/5077)
+- Fix #parameters mistakes keyword "splat" for a block parameter. [#5066](https://github.com/mruby/mruby/issues/5066)
+- Fix mruby-io doesn't work in processes started as Windows service. [#5114](https://github.com/mruby/mruby/issues/5114)
+- Fix resuming fiber from C seems to loop infinitely. [#5261](https://github.com/mruby/mruby/issues/5261)
+- Fix invalid UTF-8 string length. [#5269](https://github.com/mruby/mruby/issues/5269)
+- Fix avoid syntax error when EXPR_MID appears in conditional operator. [#5290](https://github.com/mruby/mruby/issues/5290)
+- Fix symbols like numbered parameters in blocks get a syntax error. [#5295](https://github.com/mruby/mruby/issues/5295)
+- Avoid infinite loops when converting objects to strings. [01a8d849](https://github.com/mruby/mruby/commit/01a8d849)
+- Fix module order of `#include`. [ruby-bug:7844](https://bugs.ruby-lang.org/issues/7844)
