I am pleased to announce the release of ASDF 2.21. Since previous release 2.20, the changes are as follow:

* New features:    * Most importantly, encodings.      ASDF now lets you specify an :encoding for a system, module or component,      that is used when loading or compiling Lisp files. See the documentation.      By default, the only useful value is :utf-8, and      we recommend you use UTF-8 everywhere.      We intend to make UTF-8 the default in the future      (current default is the legacy behavior of using whichever implicit      default your underlying implementation is currently configured to use).      An extension asdf-encodings is available that supports more encodings,      including autodetection of encoding from either emacs-style declaration      -*- Mode: Lisp ; coding: utf-8 -*- or content.    * require-system works like load-system, but won't try to load or update      systems that have already been loaded, as listed by loaded-systems.      More generally, you can specify a list of systems as :force-not argument      to load-system and the specified systems won't be loaded or updated.    * You can specify :force-not and a list of systems when loading a system,    * You can now specify :hostname in your asdf-output-translations,      so you can easily share a home directory via the network      yet split its fasl cache between several subtly different machines.  * Bug Fixes:    * lp#982285. since 2.014.4, the default source-registry      was skipping anything from /usr or XDG_DATA_DIRS,      because of a missing test in getenv-absolute-pathnames. Fixed in .15.    * In 2.019.9 aka 2.20, ECL support was broken by using      a function in the wrong package (defined in cl-user). Fixed in .1.    * logical-pathname support was somewhat broken since 2.017.6,      due to the way most implementations fail to read physical namestrings      when *default-pathname-defaults* is a logical-pathname.      Fixed, together with other logical-pathname issues,      and a test case was added to the test suite to ensure no further regression.      Works great modulo quirks around implementation bugs on CLISP and Allegro.    * Make upgrading ASDF more robust on CMUCL, LispWorks, SBCL.  * Minor tweaks:    * Use :unspecific in pathname components on more implementations.    * export and/or document more utilities.    * add a few missing compatfmt for Genera.
