md = Digest::MD5.digest("string")
|
|

|
|
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")
|
|
|
|
* Digest::Base#==
|
|
|
|
* self == string
|
|
|
|
Automatic detection between binary digest values and hexadecimal
|
|
digest values has been dropped. It is always assumed that a
|
|
hexadecimal digest value is given for comparison.
|
|
|
|
* self == md
|
|
|
|
Digest objects are compared by the resulting digest values, not
|
|
by the exact vector states.
|
|
|
|
* 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.
