+== Version 4.1.0
+
+Many small bug fixes in this release. But there are some new features also.
+There's now an `lto` feature to specify the use of LTO, and what kind. The
+existing `stdlib` feature now has real values and corresponding options
+for some toolsets. But most importantly there's new documentation for all
+the features.
+
+Thank to all the users that contributed to this release with these changes:
+
+* Support for VS2019 for intel-vin 19.0. -- _Edward Diener_
+* Fix compiler warnings about `-std=gnu11` when building `b2` on Cygwin. --
+  _Andrey Semashev_
+* Add example of creating multiple PCHs for individual headers.
+  -- _Rene Rivera_
+* Add QNX threading flags for GCC toolset. -- _Aurelien Chartier_
+* Fix version option for IBM and Sun compilers when building b2 engine
+  -- _Juan Alday_
+* Rename `strings.h` to `jam_strings.h` in `b2` engine to avoid clash with
+  POSIX `strings.h` header. -- _Andrey Semashev_
+* Add options for `cxxstd` feature for IBM compiler. -- _Edward Diener_
+* Many fixes to intel-win toolset. -- _Edwad Diener_
+* Add z15 instruction set for gcc based toolsets. -- _Neale Ferguson_
+* Improve using MSVC from a Cygwin shell. -- _Michael Haubenwallner_
+* Add LTO feature and corresponding support for gcc and clang toolsets.
+  -- _Dmitry Arkhipov_
+* Fix errors when a source doesn't have a type. -- _Peter Dimov_
+* Add documentation for features. -- _Dmitry Arkhipov_
+* Enhance `stdlib` feature, and corresponding documentation, for clang, gcc,
+  and sun toolsets. -- _Dmitry Arkhipov_
+* Install rule now makes explicit only the immediate targets it creates.
+  --  _Dmitry Arkhipov_
+* Add armasm (32 and 64) support for msvc toolset. -- _Michał Janiszewski_
+* Fix errors with custom un-versioned gcc toolset specifications.
+  -- _Peter Dimov_
+* Allow arflags override in gcc toolset specifications. -- _hyc_
+* Fix founds libs not making it to the clang-win link command line.
+  -- _Peter Dimov_
+* Updated intel-win toolset to support for Intel C++ 19.1.
+  -- _Edward Diener_
+* Detect difference between MIPS32 and MIPS64 for OS in b2 engine.
