+* Changes in 0.8.1 (since 0.8)
+
+** Package management
+
+*** New ‘--share’ and ‘--expose’ options for ‘guix system vm’
+
+See “Invoking guix system” in the manual.
+
+*** Emacs mode now automatically loads newly installed Emacs packages
+
+See “Emacs Initial Setup” in the manual.
+
+*** ‘guix-daemon’ now defaults to ‘--cores=0 --jobs=1’
+
+In other words, at any given time, only one derivation is being built or
+substituted, and it can use as many cores as available.  Before, there could
+be N derivations using N cores, which was obviously not desirable.
+
+*** Command-line tools support the ‘GUIX_BUILD_OPTIONS’ environment variable
+
+See “Invoking guix build” in the manual.
+
+*** ‘guix environment’ is faster
+
+*** New ‘--recursive’ option for ‘guix archive’
+
+See “Invoking guix archive” in the manual.
+
+*** Missing patches required by a package definition are gracefully reported
+
+*** ‘guix lint’ supports additional checkers
+
+The new checkers are ‘gnu-description’, ‘home-page’, and ‘source’.
+See “Invoking guix lint” in the manual.
+
+*** New CPAN importer for ‘guix import’
+
+See “Invoking guix import” in the manual.
+
+
+** Distribution
+
+*** USB installation image has more tools
+
+Tools added since 0.8: wpa_supplicant, cryptsetup, and iw.
+
+*** Linux kernel module dependencies are automatically handled
+
+Before that, all the modules needed in the initrd would need to be explicitly
+listed, including their dependencies, and in topological order.
+
+*** Font packages now all have a name starting with ‘font-’
+
+See “Fonts” in the manual.
+
+*** Shell startup files have been cleaned up
+
+/etc/profile contains only environment variable definitions, which may also be
+used when running a different shell.  The skeletons for user’s ‘.bash_profile’
+and ‘.bashrc’ files behave as documented in the Bash manual.  Zsh is supported.
+
+*** The ‘root’ account gets a copy of the account skeleton files
+
+Before that, the skeleton files would only be copied to non-root accounts.
+
+*** The name service cache daemon (nscd) is configurable
+
+By default it aggressively caches host and service lookups.  See “Base
+Services” in the manual.
+
+*** Available locale definitions are now declared in ‘operating-system’
+
+Before, the ‘glibc’ package would contain all the existing locales, as well as
+the ‘locale-archive’ file, amounting to 110 MiB.  See “Locales” in the manual.
+
+*** SLiM sessions are configurable
+
+Pressing F1 in the SLiM graphical log-in screen allows users to choose among
+the pre-configured session types.  See “X Window” in the manual.
+
+*** Man pages and Info files are systematically gzip-compressed
+
+*** ‘gnu-build-system’ ensures that documentation is in share/{man,info}
+
+If a package installs to $prefix/{man,info}, this is automatically fixed to be
+$prefix/share/{man,info}.
+
+*** ‘strip’ is invoked only on ELF files and ‘ar’ archives
+
+*** ‘libtool’ and ‘libltdl’ are now separate packages
+
+*** Emacs mode is readily usable on the Guix System Distribution
+
+*** Substitutes are now enabled by default on freshly installed systems
+
+** Programming interfaces
+
+*** New (guix elf) and (gnu build linux-modules) modules
+
+These provide resolution of Linux kernel module dependencies.  See
+<https://lists.gnu.org/archive/html/guix-devel/2014-11/msg00670.html>.
+
+*** ‘glib-or-gtk-build-system’ has been extended
+
+It now handles GIO and XDG themes, takes care of generating the icon cache,
+and has a new #:glib-or-gtk-wrap-excluded-outputs parameter.
+
+*** ‘search-path-specification’ can now specify non-directory items
+
+For example, the ‘search-path-specification’ attached to libxml2 specifies a
+file pattern, which allows all the ‘catalog.xml’ files to be added to the
+‘XML_CATALOG_FILES’ environment variable.
+
+*** (guix build syscalls) has more network-related procedures
+
+‘set-network-interface-flags’, ‘set-network-interface-address’,
+‘network-interface-address’, and ‘configure-network-interface’ are ioctl
+bindings used by network-handling dmd services.
+
+*** (guix monads) refactoring
+
+‘%store-monad’ is now in (guix store) and is an alias for the new
+‘%state-monad’ provided by (guix monads).  Monadic procedures dealing with the
+store, with derivations, and with packages have been moved from (guix monads)
+to (guix store), (guix derivations), and (guix packages).  See “The Store
+Monad” in the manual.
+
+*** (guix build utils) provides ‘parallel-job-count’
+
+*** ‘wrap-program’ preserves the original argv[0]
+
+*** New (guix sets) module
+
+*** ‘define-record-type*’ now support “delayed” fields
+
