* Installation Changes in Emacs 26.1
+---
** By default libgnutls is now required when building Emacs.
Use 'configure --with-gnutls=no' to build even when GnuTLS is missing.
+---
** GnuTLS version 2.12.2 or later is now required, instead of merely
version 2.6.6 or later.
++++
** The new option 'configure --with-mailutils' causes Emacs to rely on
GNU Mailutils to retrieve email. It is recommended, and is the
default if GNU Mailutils is installed. When --with-mailutils is not
--with-mailutils or --without-pop when configuring; --without-pop
is the default on platforms other than native MS-Windows.
+---
** The new option 'configure --enable-gcc-warnings=warn-only' causes
GCC to issue warnings without stopping the build. This behavior is
now the default in developer builds. As before, use
'--disable-gcc-warnings' to suppress GCC's warnings, and
'--enable-gcc-warnings' to stop the build if GCC issues warnings.
+---
** When GCC warnings are enabled, '--enable-check-lisp-object-type' is
now enabled by default when configuring.
(If your Emacs is installed in a non-standard location, you may
need to copy the emacs.service file to eg ~/.config/systemd/user/)

** New configure option '--disable-build-details' attempts to build an
Emacs that is more likely to be reproducible; that is, if you build
and install Emacs twice, the second Emacs is a copy of the first.
color metrics 'lcms-cie-de2000' and 'lcms-cam02-ucs', as well as
functions for conversion to and from CIE CAM02 and CAM02-UCS.
+---
** The configure option '--with-gameuser' now defaults to 'no',
as this appears to be the most common configuration in practice.
When it is 'no', the shared game directory and the auxiliary program
update-game-score are no longer needed and are not installed.
+---
** Emacs no longer works on IRIX. We expect that Emacs users are not
affected by this, as SGI stopped supporting IRIX in December 2013.

+*** Emacsclient has a new option '-T' / '--tramp'.
This helps with using a local Emacs session as the server for a remote
emacsclient. With appropriate setup, one can now set the EDITOR
environment variable on a remote machine to emacsclient, and
use the local Emacs to edit remote files via Tramp. See the node
"(emacs) emacsclient Options" in the user manual for the details.
++++
+*** Emacsclient now accepts command-line options in ALTERNATE_EDITOR
+and '--alternate-editor'. For example, ALTERNATE_EDITOR="emacs -Q -nw".
+Arguments may be quoted "like this", so that for example an absolute
+path containing a space may be specified; quote escaping is not
+supported.

** New user option 'dig-program-options' and extended functionality
for DNS-querying functions 'nslookup-host', 'dns-lookup-host',

instead.

*** In 'message-citation-line-format' the '%Z' format is now the time
zone name instead of the numeric form. The '%z' format continues to
be the numeric form. The new behavior is compatible with

with blank space to eshell history.

+(i.e., BBDB 2.x) is deprecated and will likely be removed in the next

*** 'message-beginning-of-line' (bound to 'C-a') understands folded headers.
In 'visual-line-mode' it will look for the true beginning of a header
while in non-'visual-line-mode' it will move the point to the indented
contents of the buffer to determine whether it's a C or C++ source
file.
