== Changes since the 1.9.1 release
11
== Changes since the 1.9.2 release
14
* Ruby's License is changed from a dual license with GPLv2
15
to a dual license with 2-clause BSDL.
17
=== Known platform dependent issues
20
* You have to configure ruby with '--with-gcc=gcc-4.2' if you're using
21
Xcode 4.1, or, if you're using Xcode 4.2, you have to configure ruby
22
with '--with-gcc=clang'.
26
* rb_scan_args() is enhanced with support for option hash argument
29
* ruby_vm_at_exit() added. This enables extension libs to hook a VM
32

127
* Kernel#respond_to_missing?
128
* Kernel#singleton_class

136
* Kernel#instance_eval yields the receiver.
144
On Windows, the current directory is no longer implicitly
145
prepended to the default command search path, just like other

* Time.new have optional arguments to specify date with time offset.
190
* Time#getlocal, Time#localtime have optional time offset argument.
197
* incompatible changes:
198
* The year argument of Time.{utc,gm,local,mktime} is now interpreted as
199
the value itself. For example, Time.utc(99) means the year 99 AD,
108
* Time#strftime supports %:z and %::z.
111
* Process#maxgroups and Process#maxgroups= now raise NotImplementedError if
112
the platform don't support supplementary groups concept.
116
* BigDecimal#power and BigDecimal#** support non-integral exponent.
118
* Kernel.BigDecimal and BigDecimal.new now accept instances of Integer,
119
Rational, Float, and BigDecimal. If you pass a Rational or a Float to
120
them, you must specify the precision to produce the digits of a BigDecimal.
122
* The behavior of BigDecimal#coerce with a Rational is changed. It uses
123
the precision of the receiver BigDecimal to produce the digits of a
124
BigDecimal from the given Rational.
128

This feature is removed at the next release of bigdecimal.
140
* A negative precision isn't supported.
141
Be careful it is an incompatible change.
145
* Accepts flonum explicitly with limitations.
146
* If the given offset is flonum, DateTime assumes its precision is
149
DateTime.new(2001,2,3,0,0,0,3.0/24) ==
150
DateTime.new(2001,2,3,0,0,0,'+03:00')
153
* If the given operand for -/+ is flonum, DateTime assumes its
154
precision is at most nanosecond.
156
DateTime.new(2001,2,3) + 0.5 == DateTime.new(2001,2,3,12)
159
* Precision of offset is always at most second.
161
Rational('0.5') == Rational('0.500001') #=> false
162
DateTime.new(2001,2,3,0,0,0,Rational('0.5')) ==
163
DateTime.new(2001,2,3,0,0,0,Rational('0.500001'))
166
* Ignores long offset and far reform day (with warning).
170
-1<=offset<=1 (-24:00..+24:00)
171
2298874<=start<=2426355 or -/+oo
172
(proleptic Gregorian/Julian mean -/+oo)
174
* A method strftime cannot produce huge output (same as Time's one).
176
* Even though Date/DateTime can handle far dates, the following causes
179
DateTime.new(1<<10000).strftime('%Y') # Errno::ERANGE
181
* Changed the format of inspect.
182
* Changed the format of marshal (but, can load old dumps).
204
* Digest::Class.base64digest
205
* Digest::Instance#base64digest
206
* Digest::Instance#base64digest!
208
* Digest::HMAC (digest/hmac) has been marked as deprecated because
209
it was unintentional for the experimental library to be included
210
in the final release of 1.9.1. Please use OpenSSL::HMAC instead.
217
* raise an exception not returns nil for invalid feed making.
221
* new method to return maker class.
223
* RSS::Maker.supported?(version)
224
* new method to check whether given version is supported.
226
* RSS::Maker: item.guid.permanent_link?
227
* new alias of item.guid.isPermaLink
228
* RSS::Maker: item.guid.permanent_link=
229
* new alias of item.guid.isPermaLink=
232
* Now uses libffi as a backend if avaiable.
233
It means DL works fine on more platforms.
236
* A lightweight wrapper for libffi.
239
* Now uses libyaml as a backend if available.
240
It means YAML library supports new standards for YAML.
243
* A wrapper for libyaml.
246
* Update to JSON 1.1.9
250
* REXML::Document.entity_expansion_limit=
252
New method to set the entity expansion limit. By default the limit is
253
set to 10000. See the following URL for details.
255
http://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/
259
* Updated to RDoc 2.5.8
263
* Updated to RubyGems 1.3.7
267
* imported upstream version (logger/1.2.7)
268
* do not raise an exception even if log writing failed.
269
* do not raise ShiftingError if an aged file already exists.
270

274
* Matrices must now be rectangular.

* deprecated methods:
232
* SNI (Server Name Indication) supported for HTTPS.
234
* Allow to configure to wait server returning '100 continue' response
235
before sending HTTP request body. Set Net::HTTP#continue_timeout AND pass
236
'expect' => '100-continue' to a extra HTTP header.
238
For example, the following code sends HTTP header and waits for getting
239
'100 continue' response before sending HTTP request body. When 0.5 [sec]
240
timeout occurs or the server send '100 continue', the client sends HTTP
242
http.continue_timeout = 0.5
243
http.request_post('/continue', 'body=BODY', 'expect' => '100-continue')

* Socket#{recvfrom,recvfrom_nonblock,accept,accept_nonblock,sysaccept}
335
returns a sender address as Addrinfo object instead of a binary sockaddr string.
336
Addrinfo#to_s returns the old binary sockaddr string.
337
* BasicSocket#getsockopt returns Socket::Option object instead of a binary string.
338
Socket::Option#to_s returns the old binary string.

374
* BasicSocket#getsockopt accepts a Socket::Option object.
375
* Socket.getaddrinfo and IPSocket#{addr,peeraddr} accept an optional
376
argument to turn reverse lookup on/off.
378
* constant names can be accepted as well as constant values.
379
i.e. Socket.new(:PF_INET, :SOCK_STREAM, 0)
380
The constant names can be specified without the prefix.
381
i.e. Socket.new(:INET, :STREAM, 0)
382
* protocol/address family
384
* socket option protocol level
386
* shutdown's argument
254
* PKey::RSA and PKey::DSA now use the generic X.509 encoding scheme
255
(e.g. used in a X.509 certificate's Subject Public Key Info) when

257
ensured by (already existing) fallbacks during creation.
