|
(The default of :close_others option is changed to true by default.)

|
|
* Net::IMAP.default_port
|
|
* Net::IMAP.default_imap_port
|
|
* Net::IMAP.default_tls_port
|
|
* Net::IMAP.default_ssl_port
|
|
* Net::IMAP.default_imaps_port
|
|
|
|

|
* OpenStruct#to_h converts the struct to a hash.
|

|
array, each of which is stringified using to_s.
|
|
|
|
* lib/tmpdir.rb
|
|
* 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.
|
|
|

|
|
* Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.

|
* 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.

|
=== Language changes
|
|

|
|
|
|
* 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.
