+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Renamed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;uniform_int&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;uniform_real&lt;/span&gt;&lt;/code&gt;

+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Added members to all distributions: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;param_type&lt;/span&gt;&lt;/code&gt;,
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;param&lt;/span&gt;&lt;/code&gt;, stream

+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;max&lt;/span&gt;&lt;/code&gt;.

+ use of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;variate_generator&lt;/span&gt;&lt;/code&gt;.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Changed the meaning of the parameters of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;

+ &lt;/li&gt;
+ &lt;li&gt;

+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;seed_seq&lt;/span&gt;&lt;/code&gt;
+ and added the corresponding constructors and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;seed&lt;/span&gt;&lt;/code&gt; overloads the generators.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generate_canonical&lt;/span&gt;&lt;/code&gt;.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Renamed the engine tempates. e.g. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mersenne_twister&lt;/span&gt;&lt;/code&gt;
+ becomes &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mersenne_twister_engine&lt;/span&gt;&lt;/code&gt;.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ New engine adapter &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;independent_bits_engine&lt;/span&gt;&lt;/code&gt;.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Added new predefined engine typedefs: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mt19937_64&lt;/span&gt;&lt;/code&gt;,
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ranlux&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;24&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;|&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;48&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;][&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_base&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;]&lt;/span&gt;&lt;/code&gt;,
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;knuth_b&lt;/span&gt;&lt;/code&gt;.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Updated seeding algorithms.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;discard&lt;/span&gt;&lt;/code&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Use unsigned types instead of signed types in all the predefined
+ engines.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;/ul&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Bug fixes:
+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;linear_congruential_engine&lt;/span&gt;&lt;/code&gt;
+ could assert because the modular arithmetic was not implemented
+ in all cases. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shuffle_output&lt;/span&gt;&lt;/code&gt;,
+ now called &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shuffle_order_engine&lt;/span&gt;&lt;/code&gt;,
+ could cause integer overflow. These cases were not triggered
+ by any predefined engines.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;uniform_small_int&lt;/span&gt;&lt;/code&gt;
+ now actually behaves as documented.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;/ul&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ New efficient algorithms for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;binomial_distribution&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;poisson_distribution&lt;/span&gt;&lt;/code&gt;.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Moved all features into &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;namespace&lt;/span&gt;
+ &lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;random&lt;/span&gt;&lt;/code&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Backwards compatibility issues:
+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ The seeding algorithms have changed. This was unavoidable for
+ compatibility with the standard. Not to mention that some of
+ the existing algorithms were weird and inconsistent.
+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Seeding with an integer: The behaviour should be unchanged
+ for most generators except &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lagged_fibonacci&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;subtract_with_carry&lt;/span&gt;&lt;/code&gt;
+ (and thus &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ranlux&lt;/span&gt;&lt;/code&gt;).
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Seeding a generator with another generator: This has
+ been enabled by making all all generators models of
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SeedSeq&lt;/span&gt;&lt;/code&gt;.
+ Therefore, if you seed a Boost.Random generator with
+ a non Boost.Random generator, your code will no longer
+ compile. The algorithm has changed, so code using this
+ seeding method will yield different values.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Seeding a generator from a pair of iterators: This implicitly
+ assumed that the elements were 32-bit integers in some
+ places, but not everywhere. I've added this requirement
+ everywhere and updated the algorithms accordingly. The
+ behaviour of generators with a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value_type&lt;/span&gt;&lt;/code&gt;
+ no more than 32 bits should be unchanged.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;/ul&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Renaming:
+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Whenever a class was renamed, there is a wrapper with
+ the old name. There are also using declarations in namespace
+ boost for everything that was moved.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ The names of a few accessors in the distributions changed.
+ Both the old and the new names are allowed.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;/ul&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt;:
+ The behaviour is different at runtime. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt; provide
+ the old behaviour, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;random&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;random&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt; provide
+ the new behaviour.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Streaming: gamma_distribution has a new parameter, thus text
+ saved with the old version will not readable by the new version.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;variate_generator&lt;/span&gt;&lt;/code&gt;
+ is now a simple pass through wrapper. Code that assumes that
+ it will adjust the generator's result type to match the distribution
+ will no longer work. This is not an issue with any of the distributions
+ provided by Boost.Random.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Return types: The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;result_types&lt;/span&gt;&lt;/code&gt;
+ of some generators have changed slightly. Some signed types
+ have changed to unsigned to match the standard.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;has_fixed_range&lt;/span&gt;&lt;/code&gt;:
+ This is now always false, as it doesn't appear to be very useful
+ and is excessively cumbersome. Anything that was accessing
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;const_min&lt;/span&gt;&lt;/code&gt; and
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;const_max&lt;/span&gt;&lt;/code&gt; without
+ first checking &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;has_fixed_range&lt;/span&gt;&lt;/code&gt;
+ was incorrect to begin with.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;/ul&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;/ul&gt;
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
           &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/range/index.html&quot;&gt;Range&lt;/a&gt;:&lt;/span&gt;

+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ The seeding algorithms have changed. This was unavoidable for
+ compatibility with the standard. Not to mention that some of
+ the existing algorithms were weird and inconsistent.
+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Seeding with an integer: The behaviour should be unchanged
+ for most generators except &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lagged_fibonacci&lt;/span&gt;&lt;/code&gt;
+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;subtract_with_carry&lt;/span&gt;&lt;/code&gt;
+ (and thus &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ranlux&lt;/span&gt;&lt;/code&gt;).
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Seeding a generator with another generator: This has
+ been enabled by making all all generators models of
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SeedSeq&lt;/span&gt;&lt;/code&gt;.
+ Therefore, if you seed a Boost.Random generator with
+ a non Boost.Random generator, your code will no longer
+ compile. The algorithm has changed, so code using this
+ seeding method will yield different values.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ Seeding a generator from a pair of iterators: This implicitly
+ assumed that the elements were 32-bit integers in some
+ places, but not everywhere. I've added this requirement
+ everywhere and updated the algorithms accordingly. The
+ behaviour of generators with a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value_type&lt;/span&gt;&lt;/code&gt;
+ no more than 32 bits should be unchanged.
+ &lt;/div&gt;

+ boost for everything that was moved.
+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;
+ The names of a few accessors in the distributions changed.
+ Both the old and the new names are allowed.
+ &lt;/div&gt;
+ &lt;/li&gt;

+ The behaviour is different at runtime. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;

+ Streaming: gamma_distribution has a new parameter, thus text
+ saved with the old version will not readable by the new version.
+ &lt;/div&gt;

+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;variate_generator&lt;/span&gt;&lt;/code&gt;
+ is now a simple pass through wrapper. Code that assumes that
+ it will adjust the generator's result type to match the distribution

+ of some generators have changed slightly. Some signed types

+ &lt;li&gt;
+ &lt;div&gt;
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;has_fixed_range&lt;/span&gt;&lt;/code&gt;:
+ This is now always false, as it doesn't appear to be very useful
+ and is excessively cumbersome. Anything that was accessing
+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;const_min&lt;/span&gt;&lt;/code&gt; and

+ Synchronized with the new standard.
+ &lt;ul&gt;
+ &lt;li&gt;
+ &lt;div&gt;

+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;

+ and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;uniform_real&lt;/span&gt;&lt;/code&gt;

+ &lt;/div&gt;
+ &lt;/li&gt;
+ &lt;li&gt;
+ &lt;div&gt;

+ &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;param&lt;/span&gt;&lt;/code&gt;, stream

+ &lt;/div&gt;
+ &lt;/li&gt;

+ <li>
+ <div>
+ Allow distributions to be used directly with generators without
+ use of <code><span class="identifier">variate_generator</span></code>.
+ </div>
+ </li>
+ <li>
+ <div>
+ Changed the meaning of the parameters of <code><span class="identifier">geometric_distribution</span></code>
+ and <code><span class="identifier">lognormal_distribution</span></code>.
+ </div>
+ </li>
+ <li>
+ <div>
+ Added a second parameter to <code><span class="identifier">gamma_distribution</span></code>.
+ </div>

+ <li>

+ </li>
+ <li>
+ <div>
+ Added <code><span class="identifier">generate_canonical</span></code>.
+ </div>
+ </li>
+ <li>

+ Bug fixes:
+ <ul>
+ <li>
+ <div>
+ <code><span class="identifier">linear_congruential_engine</span></code>
+ could assert because the modular arithmetic was not implemented
+ in all cases. <code><span class="identifier">shuffle_output</span></code>,
+ now called <code><span class="identifier">shuffle_order_engine</span></code>,
+ could cause integer overflow. These cases were not triggered
+ by any predefined engines.
+ </div>
+ </li>
+ <li>
+ <div>
+ <code><span class="identifier">uniform_small_int</span></code>
+ now actually behaves as documented.
+ </div>
+ </li>
+ </ul>
+ </div>
+ </li>
+ <li>
+ <div>
+ New efficient algorithms for <code><span class="identifier">binomial_distribution</span></code>
+ and <code><span class="identifier">poisson_distribution</span></code>.
+ </div>
+ </li>
+ <li>
+ <div>
+ Moved all features into <code><span class="keyword">namespace</span>
+ <span class="identifier">boost</span><span class="special">::</span><span class="identifier">random</span></code>
+ </div>
+ </li>
+ <li>
+ <div>
+ Backwards compatibility issues:
+ <ul>
+ <li>
+ <div>
+ The seeding algorithms have changed. This was unavoidable for
+ compatibility with the standard. Not to mention that some of
+ the existing algorithms were weird and inconsistent.
+ <ul>
+ <li>
+ <div>
+ Seeding with an integer: The behaviour should be unchanged
+ for most generators except <code><span class="identifier">lagged_fibonacci</span></code>
+ and <code><span class="identifier">subtract_with_carry</span></code>
+ (and thus <code><span class="identifier">ranlux</span></code>).
+ </div>
+ </li>
+ <li>
+ <div>
+ Seeding a generator with another generator: This has
+ been enabled by making all all generators models of
+ <code><span class="identifier">SeedSeq</span></code>.
+ Therefore, if you seed a Boost.Random generator with
+ a non Boost.Random generator, your code will no longer
+ compile. The algorithm has changed, so code using this
+ seeding method will yield different values.
+ </div>
+ </li>
+ <li>
+ <div>
+ Seeding a generator from a pair of iterators: This implicitly
+ assumed that the elements were 32-bit integers in some
+ places, but not everywhere. I've added this requirement
+ everywhere and updated the algorithms accordingly. The
+ behaviour of generators with a <code><span class="identifier">value_type</span></code>
+ no more than 32 bits should be unchanged.
+ </div>
+ </li>
+ </ul>
+ </div>
+ </li>
+ <li>
+ <div>
+ Renaming:
+ <ul>
+ <li>
+ <div>
+ Whenever a class was renamed, there is a wrapper with
+ the old name. There are also using declarations in namespace
+ boost for everything that was moved.
+ </div>
+ </li>
+ <li>
+ <div>
+ The names of a few accessors in the distributions changed.
+ Both the old and the new names are allowed.
+ </div>
+ </li>
+ </ul>
+ </div>
+ </li>
+ <li>
+ <div>
+ <code><span class="identifier">geometric_distribution</span></code>
+ and <code><span class="identifier">lognormal_distribution</span></code>:
+ The behaviour is different at runtime. <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">geometric_distribution</span></code>
+ and <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">lognormal_distribution</span></code> provide
+ the old behaviour, <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">random</span><span class="special">::</span><span class="identifier">geometric_distribution</span></code>
+ and <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">random</span><span class="special">::</span><span class="identifier">lognormal_distribution</span></code> provide
+ the new behaviour.
+ </div>
+ </li>
+ <li>
+ <div>
+ Streaming: gamma_distribution has a new parameter, thus text
+ saved with the old version will not readable by the new version.
+ </div>
+ </li>
+ <li>
+ <div>
+ <code><span class="identifier">variate_generator</span></code>
+ is now a simple pass through wrapper. Code that assumes that
+ it will adjust the generator's result type to match the distribution
+ will no longer work. This is not an issue with any of the distributions
+ provided by Boost.Random.
+ </div>
+ </li>
+ <li>
+ <div>
+ Return types: The <code><span class="identifier">result_types</span></code>
+ of some generators have changed slightly. Some signed types
+ have changed to unsigned to match the standard.
+ </div>
+ </li>
+ <li>
+ <div>
+ <code><span class="identifier">has_fixed_range</span></code>:
+ This is now always false, as it doesn't appear to be very useful
+ and is excessively cumbersome. Anything that was accessing
+ <code><span class="identifier">const_min</span></code> and
+ <code><span class="identifier">const_max</span></code> without
+ first checking <code><span class="identifier">has_fixed_range</span></code>
+ was incorrect to begin with.
+ </div>
+ </li>
+ </ul>
+ </div>
+ </li>
+ </ul>
+ </div>
