+** Announcement
+Dear Community,
+
+After more than three years of development, we are proud to announce a new
+ECL release having the version tag `20.4.24`. During that time many
+important improvements have been made including bug fixes, stability
+enhancements and new features. Changes include but are not limited to:
+
+- package local nicknames support
+- atomic operations support
+- specialized representations of complex float types
+- a port to the iOS platform
+- fixes for weak hash tables and weak pointers
+- fixes for race conditions in the ECL internals
+- hash table extensions (synchronization and custom test functions)
+- better MOP conformance and improved meta-stability
+- improvements to the manual
+
+For more information please read the file CHANGELOG which is located in the
+source code, and browse commits. We'd like to thank all people who made
+this release possible by contributions of code, documentation, issue
+reports, testing and others. Some of them are listed here (without any
+particular order): Paul Ruetz, Karsten Poeck, Vadim Penzin, Roger Sen, Stas
+Boukarev, Michael Fox, Erik Bray, Bo Yao, Jeremy Cooper, Florian Margaine,
+Fabrizio Fabbri, Tomek Kurcz, Kris Katterjohn, Marcin Kolenda, Zhang Yuguo,
+Sébastien Villemot, Moritz Petersen, Marius Gerbershagen and Daniel
+Kochmański. We'd also like to thank the company Rigetti Computing for
+sponsoring the work on specialized complex float representations.
+
+We have another important announcement we'd like to make. Embeddable
+Common-Lisp project has now two maintainers: Daniel Kochmański and Marius
+Gerbershagen. After numerous contributions from Marius I've proposed him
+this responsibility and to my rejoice he has accepted it. That reflects our
+community growth.
+
+This release is available for download in a form of a source code archive
+(we do not ship prebuilt binaries):
+
+- [ECL 20.4.24 tarball archive](https://common-lisp.net/project/ecl/static/files/release/ecl-20.4.24.tgz)
