= NEWS This document is a list of user visible feature changes made between releases except for bug fixes. Note that each entry is kept so brief that no reason behind or reference information is supplied with. For a full list of changes with all sufficient information, see the ChangeLog file. * REXML * REXML::Document.entity_expansion_limit= New method to set the entity expansion limit. By default the limit is set to 10000. See the following URL for details. http://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/ == Changes since the 1.8.6 release === Configuration changes * vendor_ruby directory A new library directory named `vendor_ruby' is introduced in addition to `site_ruby'. The idea is to separate libraries installed by the package system (`vendor') from manually (`site') installed libraries preventing the former from getting overwritten by the latter, while preserving the user option to override vendor libraries with site libraries. (`site_ruby' takes precedence over `vendor_ruby') If you are a package maintainer, make each library package configure the library passing the `--vendor' option to `extconf.rb' so that the library files will get installed under `vendor_ruby'. You can change the directory locations using configure options such as `--with-sitedir=DIR' and `--with-vendordir=DIR'. === Global constants * new constants * RUBY_COPYRIGHT * RUBY_DESCRIPTION === Library updates (outstanding ones only) * new library * securerandom * builtin classes * Array#flatten * Array#flatten!

(alias length and size) * String#chars * String#each_char * String#lines * String#partition * String#rpartition * String#start_with? * String#end_with? New methods. These are $KCODE aware unlike #index, #rindex and #include?. * String#each_byte * String#each * String#each_line * String#gsub(pattern) Return an enumerator if no block is given. * String#upto An optional second argument is added to specify if the last value should be included. * StopIteration New exception class that causes Kernel#loop to stop iteration when raised. * Struct#each * Struct#each_pair Return an enumerator if no block is given. * Symbol#to_proc New method. * __method__ New global function that returns the name of the current method as a Symbol. * enumerator * Enumerator is now a built-in module. The #next and #rewind methods are implemented using the "generator" library. Use with care and be aware of the performance loss. * ipaddr * New methods * IPAddr#<=> * IPAddr#succ IPAddr objects are now comparable and enumerable having these methods. This also means that it is possible to have a Range object between two IPAddr objects. * IPAddr#to_range A new method to create a Range object for the (network) address. * Type coercion support * IPAddr#& * IPAddr#| * IPAddr#== * IPAddr#include? These methods now accept a string or an integer instead of an IPAddr object as the argument. * net/smtp * Support SSL/TLS. * openssl * New classes * OpenSSL::PKey::EC * OpenSSL::PKey::EC::Group * OpenSSL::PKey::EC::Point * OpenSSL::PKey::PKCS5 * OpenSSL::SSL::Session * Documentation! * Various new methods (see documentation). * Remove redundant module namespace in Cipher, Digest, PKCS7, PKCS12.

To specify a suffix, pass an array of [basename, suffix] as the first argument. Tempfile.open(['image', 'jpg']) { |tempfile| ... } * tmpdir * New method: * Dir.mktmpdir * uri * added LDAPS scheme. * Change for RFC3986: * FTP * URI('ftp://example.com/foo').path #=> 'foo' * URI('ftp://example.com/%2Ffoo').path #=> '/foo' * URI::FTP.build([nil, 'example.com', nil, '/foo', 'i').to_s #=> 'ftp://example.com/%2Ffoo;type=i' * URI merge * URI('http://a/b/c/d;p?q').merge('?y') == URI('http://a/b/c/d;p?y') * URI('http://a/b/c/d;p?q').merge('/./g') == URI('http://a/g') * URI('http://a/b/c/d;p?q').merge('/../g') == URI('http://a/g') * URI('http://a/b/c/d;p?q').merge('../../../g') == URI('http://a/g') * URI('http://a/b/c/d;p?q').merge('../../../../g') == URI('http://a/g') * rss * 0.1.6 -> 0.2.4 * Fix image module URI * Atom support * ITunes module support * Slash module support * content:encoded with RSS 2.0 support === Interpreter Implementation * passing a block to a Proc [experimental] This implementation in current shape is known to be buggy/broken, especially with nested block invocation. Take this as an experimental feature. * stack trace On non-SystemStackError exception, full stack trace is shown. === Compatibility issues (excluding feature bug fixes) * String#slice! had some unintentional bugs and they have been fixed because either they disagreed with documentation or their respective behavior of #slice. Unfortunately, this causes some incompatibilities in the following (somewhat rare) cases. * #slice! no longer expands the array when an out-of-boundary value is given. # Ruby 1.8.6 a = [1,2] a.slice!(4,0) #=> nil a #=> [1,2,nil,nil] # Ruby 1.8.7 a = [1,2] a.slice!(4,0) #=> nil a #=> [1,2] * #slice! no longer raises an exception but returns nil when a negative length or out-of-boundary negative position is given. # Ruby 1.8.6 a = [1,2] a.slice!(1,-1) #=> (raises IndexError) a.slice!(-5,1) #=> (raises IndexError) # Ruby 1.8.7 a = [1,2] a.slice!(1,-1) #=> nil a.slice!(-5,1) #=> nil * String#to_i, String#hex and String#oct no longer accept a sequence of underscores (`__') as part of a number. # Ruby 1.8.6 '1__0'.to_i #=> 10 '1__0'.to_i(2) #=> 2 # 0b10 '1__0'.oct #=> 8 # 010 '1__0'.hex #=> 16 # 0x10 # Ruby 1.8.7 '1__0'.to_i #=> 1 '1__0'.to_i(2) #=> 1 '1__0'.oct #=> 1 '1__0'.hex #=> 1 The old behavior was inconsistent with Ruby syntax and considered as a bug. * date * Date.parse '##.##.##' (where each '#' is a digit) is now taken as 'YY.MM.DD' instead of 'MM.DD.YY'. While the change may confuse you, you can always use Date.strptime() when you know what you are dealing with. * stringio * StringIO#each_byte The return value changed from nil to self. This is what the document says and the same as each_line() does. * tempfile * The file name format has changed. No dots are included by default in temporary file names any more. See above for how to specify a suffix. * uri * See above for details. == Changes since the 1.8.5 release === New platforms/build tools support * IA64 HP-UX * Visual C++ 8 SP1 * autoconf 2.6x === Global constants * RUBY_PATCHLEVEL New constant since 1.8.5-p1. === Library updates (outstanding ones only) * builtin classes * New method: Kernel#instance_variable_defined? * New method: Module#class_variable_defined? * New feature: Dir::glob() can now take an array of glob patterns. * date * Updated based on date2 4.0.3. * digest * New internal APIs for C and Ruby. * Support for autoloading. require 'digest' # autoloads digest/md5 md = Digest::MD5.digest("string") * New digest class methods: file * New digest instance methods: clone, reset, new, inspect, digest_length (alias size or length), block_length() * New library: digest/bubblebabble * New function: Digest(name) * fileutils * New option for FileUtils.cp_r(): :remove_destination * nkf * Updated based on nkf as of 2007-01-28. * thread * Replaced with much faster mutex implementation in C. The former implementation, which is slow but considered to be stable, is available with a configure option `--disable-fastthread'. * tk * Updated Tile extension support based on Tile 0.7.8. * Support --without-X11 configure option for non-X11 versions of Tcl/Tk (e.g. Tcl/Tk Aqua). * New sample script: irbtkw.rbw -- IRB on Ruby/Tk. It has no trouble about STDIN blocking on Windows. * webrick * New method: WEBrick::Cookie.parse_set_cookies() === Compatibility issues (excluding feature bug fixes) * builtin classes * String#intern now raises SecurityError when $SAFE level is greater than zero. * date * Time#to_date and Time#to_datetime are added as private methods. They cause name conflict error in ActiveSupport 1.4.1 and prior, which comes with Rails 1.2.2 and prior. Updating ActiveSupport and/or Rails to the latest versions fixes the problem. * digest * The constructor does no longer take an initial string to feed. The following examples show how to migrate: # Before md = Digest::MD5.new("string") # After (works with any version) md = Digest::MD5.new.update("string") # Before hd = Digest::MD5.new("string").hexdigest # After (works with any version) hd = Digest::MD5.hexdigest("string") * fileutils * A minor implementation change breaks Rake <=0.7.1. Updating Rake to 0.7.2 or higher fixes the problem. * tk * Tk::X_Scrollable (Y_Scrollable) is renamed to Tk::XScrollable (YScrollable). Tk::X_Scrollable (Y_Scrollable) is still available, but it is an alias name.
