  • (breaking change) IniFile was renamed to INI, and its method load renamed to parse
  • (breaking change) Process.getpgid was renamed to Process.pgid
  • (breaking change) An Exception's backtrace is now set when it's raised, not when it's created: it's backtrace method raises if it's not set, and there's backtrace? to get it as a nilable array
  • (breaking change) dup is now correctly implemented in all types. clone is not defined by default, but some types in the standard library do. Also check Object#def_clone
  • (breaking change) the method_missing macro only accepts a single argument: a Call now. The form that accepted 3 arguments was removed.
  • (breaking change) the delegate macro must now be used like delegate method1, method2, ..., methodN, to: object
  • (breaking change) Hash#each_with_index and Hash#each_with_object now yield a tuple (pair) and an index, because Hash is now Enumerable. Use do |(key, value), index| for this.
  • (breaking change) {"foo": 1} denotes a named tuple literal now, not a hash literal. Use {"foo" => 1} instead. This also applies to, for example HTTP::Headers{...}
  • (breaking change) Extra block arguments now give a compile-time error. This means that methods that yield more than once, one time with N arguments and another time with M arguments, with N < M, will always give an error. To fix this, add M - N nil fillers on the yield side (this makes it more explicit that nil was intended to be a block argument value)
  • (breaking change) OpenSSL::SSL::Context and OpenSSL::SSL::Socket can no longer be used directly anymore. Use their respective subclasses OpenSSL::SSL::Context::Client,
    with OpenSSL::SSL::Socket::Client, OpenSSL::SSL::Context::Server with OpenSSL::SSL::Socket::Server.
  • (breaking change) TLS server and client sockets now use sane defaults, including support for hostname verification for client sockets, used by default in HTTP::Client.
  • (breaking change) The ssl option was renamed to tls in HTTP::Client, HTTP::Server, HTTP::WebSocket, OAuth::Consumer, OAuth::Signature and OAuth2::AccessToken.
  • The dns_timeout setting in a few classes like HTTP::Client and TCPSocket is now ignored until a next version supports a non-blocking getaddrinfo equivalent
  • OpenSSL::SSL::Socket::Client supports server name indication now.
  • The build command was renamed to compile. The build command is deprecated and will be removed in a future version
  • The --cross-compile flag no longer takes arguments, use --target and -D
  • Added a Union type that represents the type of a union, which can have class methods
  • Methods, procs and lib functions that are marked as returning Void now return Nil
  • Methods that are marked as returning Nil are not checked for a correct return type, they always return nil now
  • When as fails at runtime it now includes which type couldn't be cast
  • Macros can now be used inside lib and enum declarations
  • Macros can now be declared inside enums
  • Macro calls can now be used as enum values
  • Generic types can now include a splatted type variable. This already existed in the language (Tuple(*T), Proc(*T)) but there was no syntax to define such types.
  • Class variables are now inherited (only their type, not their value). They are now similar to Ruby class instance variables.
  • Splats in yield can now be used
  • Splat in block arguments can now be used.
  • Added block auto-unpacking: if a method yields a tuple and a block specifies more then one block argument, the tuple is unpacked to these arguments
  • String literals are now allowed as external method arguments, to match named tuples and named arguments
  • sizeof and instance_sizeof can now be used as generic type arguments (mostly useful combined with StaticArray)
  • Hash, HTTP::Headers, HTTP::Params and ENV now include the Enumerable module
  • Proc is now Proc(*T, R)
  • Tuple(*T).new and NamedTuple(**T).new now correctly match the given T (#1828)
  • Float64#to_s now produces an ever more accurate output
  • JSON parsing now correctly handle floats with many digits
  • JSON.mapping and YAML.mapping now also accept named arguments in addition to a hash literal or named tuple literal
  • Int#chr now raises if the integer is out of a char's range. The old non-raising behaviour is now in Int#unsafe_chr.
  • The output of pp x is now x # => ... instead of x = ...
  • The output of the debug() macro method now tries to format the code (pass false to disable this)
  • Added JSON and YAML parsing and mapping for unions
  • Added FileUtils.cp_r (thanks @Dreauw)
  • Added Tuple.from and NamedTuple.from (thanks @jhass)
  • Added XML.escape (thanks @juanedi)
  • Added HTTP::Server::Response#respond_with_error (thanks @jhass)
  • Added TCPServer#accept?
  • Added optional base argument to Char#digit? and Char#hex? (thanks @mirek)
  • Added flag? macro method, similar to using ifdef. ifdef is deprecated and will be removed in a future version.
  • Added YAML::PullParser#read_raw
  • Added Proc#partial
  • Added Socket.ip?(str) to validate IPv4 and IPv6 addresses
  • Added Bytes as an alias of Slice(UInt8)
  • Added RangeLiteral macro methods: begin, end, excludes_end?, map and to_a
  • Added ArrayLiteral#[range] and ArrayLiteral#[from, to] in macros (applicable for TupleLiteral too)
  • Added Generic macro methods: name, type_vars, named_args
  • Spec: added JUnit formatter output (thanks @juanedi)
  • The tls option in HTTP::Client can now take a OpenSSL::SSL::Context::Client in addition to true.
  • HTTP::LogHandler logs exceptions now (thanks @jhass)
  • HTTP::ErrorHandler does not tell the client which exception occurred by default (can be enabled with a verbose flag) (thanks @jhass)
  • Several bug fixes
