- The library is fully thread safe and re-entrant provided the function and
- class templates in the library are instantiated with built-in floating point
- types: i.e. the types <code class="computeroutput"><span class="keyword">float</span></code>,
- <code class="computeroutput"><span class="keyword">double</span></code> and <code class="computeroutput"><span class="keyword">long</span>
- <span class="keyword">double</span></code>.
- </p>
-<p>
- However, the library <span class="bold"><strong>is not thread safe</strong></span>
- when used with user-defined (i.e. class type) numeric types.
- </p>
-<p>
- The reason for the latter limitation is the need to initialise symbolic constants
- using constructs such as:
- </p>
-<pre class="programlisting"><span class="keyword">static</span> <span class="keyword">const</span> <span class="identifier">T</span> <span class="identifier">coefficient_array</span> <span class="special">=</span> <span class="special">{</span> <span class="special">...</span> <span class="identifier">list</span> <span class="identifier">of</span> <span class="identifier">values</span> <span class="special">...</span> <span class="special">};</span>
-</pre>
-<p>
- Which is always thread safe when T is a built-in floating point type, but
- not when T is a user defined type: as in this case there is a need for T's
- constructors to be run, leading to potential race conditions.
- </p>
-<p>
- This limitation may be addressed in a future release.
+ The library is fully thread safe and re-entrant for all functions regards
+ of the data type they are instantiated on. Thread safety limitations relating
+ to user defined types present in previous releases (prior to 1.50.0) have
+ been removed.

[section:threads Thread Safety]
-The library is fully thread safe and re-entrant provided the function
-and class templates in the library are instantiated with
-built-in floating point types: i.e. the types `float`, `double`
-and `long double`.
-
-However, the library [*is not thread safe] when
-used with user-defined (i.e. class type) numeric types.
-
-The reason for the latter limitation is the need to
-initialise symbolic constants using constructs such as:
-
- static const T coefficient_array = { ... list of values ... };
-
-Which is always thread safe when T is a built-in floating point type,
-but not when T is a user defined type: as in this case there
-is a need for T's constructors to be run, leading to potential
-race conditions.
-
-This limitation may be addressed in a future release.
+The library is fully thread safe and re-entrant for all functions
+regards of the data type they are instantiated on. Thread safety
+limitations relating to user defined types present in previous
+releases (prior to 1.50.0) have been removed.
