Use String#encode instead. - -* io/wait - * new features: - * added IO#wait_writable method. - * added IO#wait_readable method as alias of IO#wait. - -* net/http - * new features: - * Proxies are now automatically detected from the http_proxy environment - variable. See Net::HTTP::new for details. - * gzip and deflate compression are now requested for all requests by - default. See Net::HTTP for details. - * SSL sessions are now reused across connections for a single instance. - This speeds up connection by using a previously negotiated session. - * new methods: - * Net::HTTP#local_host - * Net::HTTP#local_host= - * Net::HTTP#local_port - * Net::HTTP#local_port= - * extended method: - * Net::HTTP#connect uses local_host and local_port if specified. - -* net/imap - * new methods: - * Net::IMAP.default_port - * Net::IMAP.default_imap_port - * Net::IMAP.default_tls_port - * Net::IMAP.default_ssl_port - * Net::IMAP.default_imaps_port - -* objspace - * new method: - * ObjectSpace.reachable_objects_from(obj) - -* openssl - * Consistently raise an error when trying to encode nil values. All instances - of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an - instance whose value is nil. All instances of OpenSSL::ASN1::Constructive - raise NoMethodError in the same case. Constructing such values is still - permitted. - * TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to - :TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server - :TLSv1_1_client. The version being effectively used can be queried - with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to - blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and - OpenSSL::SSL::OP_NO_TLSv1_2. - * Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback - may be set which gets called whenever a new handshake is negotiated. This - also allows to programmatically decline (client) renegotiation attempts. - * Support for "0/n" splitting of records as BEAST mitigation via - OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS. - * OpenSSL requires passwords for decrypting PEM-encoded files to be at least - four characters long. This led to awkward situations where an export with - a password with fewer than four characters was possible, but accessing the - file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and - OpenSSL::PKey::EC therefore now enforce the same check when exporting a - private key to PEM with a password - it has to be at least four characters - long. - * SSL/TLS support for the Next Protocol Negotiation extension. Supported - with OpenSSL 1.0.1 and higher. - * OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL - is running in FIPS mode and to react to the special requirements this - might impy. - -* ostruct - * new methods: - * OpenStruct#[], []= - * OpenStruct#each_pair - * OpenStruct#eql? - * OpenStruct#hash - * OpenStruct#to_h converts the struct to a hash. - * extended method: - * OpenStruct.new also accepts an OpenStruct / Struct. - -* pathname - * extended method: - * Pathname#find returns an enumerator if no block is given. - -* rake - * rake has been updated to version 0.9.4. - - This version is backwards-compatible with previous rake versions and - contains many bug fixes. - - See - http://rake.rubyforge.org/doc/release_notes/rake-0_9_4_rdoc.html for a list - of changes in rake 0.9.3 and 0.9.4. - -* rdoc - * rdoc has been updated to version 4.0 - - This version is largely backwards-compatible with previous rdoc versions. - The most notable change is an update to the ri data format (ri data must - be regenerated for gems shared across rdoc versions). Further API changes - are internal and won't affect most users. - - See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a list of - changes in rdoc 4.0. - -* resolv - * new methods: - * Resolv::DNS#timeouts= - * Resolv::DNS::Config#timeouts= - -* rexml - * REXML::Document#write supports Hash arguments. - * REXML::Document#write supports new :encoding option. It changes - XML document encoding. Without :encoding option, encoding in - XML declaration is used for XML document encoding. - -* shellwords - * Shellwords#shellescape() now stringifies the given object using to_s. - * Shellwords#shelljoin() accepts non-string objects in the given - array, each of which is stringified using to_s. - -* syslog - * Added Syslog::Logger which provides a Logger API atop Syslog. - * Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros - are introduced for easy detection of available constants on a - running system. - -* tmpdir - * incompatible changes: - * Dir.mktmpdir uses FileUtils.remove_entry instead of - FileUtils.remove_entry_secure. This means that applications should not - change the permission of the created temporary directory to make - accessible from other users. - -* yaml - * Syck has been removed. YAML now completely depends on libyaml being - installed. - -* zlib - * Added streaming support for Zlib::Inflate and Zlib::Deflate. This allows - processing of a stream without the use of large amounts of memory. - * Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED. - * Zlib streams are now processed without the GVL. This allows gzip, zlib and - deflate streams to be processed in parallel. - -=== Language changes - - * Added %i and %I for symbol list creation (similar to %w and %W). - - * Default source encoding is changed to UTF-8. (was US-ASCII) - -=== Compatibility issues (excluding feature bug fixes) - - * Array#values_at - - See above. - - * String#lines - * String#chars - * String#codepoints - * String#bytes - - These methods no longer return an Enumerator, although passing a - block is still supported for backwards compatibility. - - Code like str.lines.with_index(1) { |line, lineno| ... } no longer - works because str.lines returns an array. Replace lines with - each_line in such cases. - - * Signal.trap - - See above. - - * Merge Onigmo. - https://github.com/k-takata/Onigmo - - * The :close_others option is true by default for system() and exec(). - Also, the close-on-exec flag is set by default for all new file descriptors. - This means file descriptors doesn't inherit to spawned process unless - explicitly requested such as system(..., fd=>fd). - - * Kernel#respond_to? against a protected method now returns false - unless the second argument is true. - - * Dir.mktmpdir in lib/tmpdir.rb - - See above. - - * OpenStruct new methods can conflict with custom attributes named - "each_pair", "eql?", "hash" or "to_h". - - * Thread#join, Thread#value - - See above. - - * Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep - - See above. |
