=== Interpreter Implementation

* stack trace

  On non-SystemStackError exception, full stack trace is shown.

=== Compatibility issues (excluding feature bug fixes)

* 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.

* 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.

* tmpdir

  * New method:
    * Dir.mktmpdir

* 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

=== 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.
