 Use C++11 range-based loops with RE/flex iterators:
 
 ```{.cpp}
-#include <reflex/stdmatcher.h> // reflex::StdMatcher, reflex::Input, std::regex
-// use a StdMatcher with std::regex to search for words in a sentence
-reflex::StdMatcher matcher("\\w+", "How now brown cow.");
+#include <reflex/pcre2matcher.h> // reflex::PCRE2TFMatcher, reflex::Input, std::regex
+// use a PCRE2UTFMatcher to search for words in a sentence
+reflex::PCRE2UTFMatcher matcher("\\w+", "How now brown cow.");
 for (auto& match : matcher.find)
   std::cout << "Found " << match.text() << std::endl;
 ```
 
+Note that we cannot generally simplify this loop to the following, because the
+temporary matcher object is destroyed (some compilers handle this in C++23):
+
+```{.cpp}
+for (auto& match : reflex::PCRE2UTFMatcher matcher("\\w+", "How now brown cow.").find);
+  std::cout << "Found " << match.text() << std::endl;
+```
+
 RE/flex also allows you to convert expressive regex syntax forms such as `\p`
 Unicode classes, character class set operations such as `[a-z--[aeiou]]`,
 escapes such as `\X`, and `(?x)` mode modifiers, to a regex string that the
 underlying regex library understands and will be able to use:
 
 - `std::string reflex::Matcher::convert(const std::string& regex, reflex::convert_flag_type flags)`
 - `std::string reflex::PCRE2Matcher::convert(const std::string& regex, reflex::convert_flag_type flags)`
+- `std::string reflex::PCRE2UTFMatcher::convert(const std::string& regex, reflex::convert_flag_type flags)`
 - `std::string reflex::BoostMatcher::convert(const std::string& regex, reflex::convert_flag_type flags)`
 - `std::string reflex::StdMatcher::convert(const std::string& regex, reflex::convert_flag_type flags)`

 - Apr 10, 2024: 4.2.1 minor update to adjust the current input pointer by one when not matching anything.
 - May 12, 2024: 4.3.0 faster `Matcher::find()` with refactored SIMD (SSE2/AVX2/AVX512BW/NEON/AArch64) code; larger default 256KB buffer (from 128KB).
 - Jun  6, 2024: 4.4.0 upgraded `reflex::Matcher` and `reflex::FuzzyMatcher` to respect Unicode word boundaries instead of only ASCII `\<`, `\>`, `\b`, `\B`; upgraded regex Unicode converters to Unicode `[::]` character classes instead of only ASCII `[[:alpha:]]` etc.; improved FSM code generation without local c0.
+- Aug  1, 2024: 4.5.0 minor speed improvements.
