By default, if 'configure' does not find a suitable libgmp, it arranges for the included mini-gmp library to be built and used.  Michael Albinus committed Nov 13, 2018 30 The new 'configure' option '--without-libgmp' uses mini-gmp even if a  Paul Eggert committed Aug 12, 2018 31 suitable libgmp is available.  Tom Tromey committed Jul 12, 2018 32   Eli Zaretskii committed Jun 07, 2019 33 34 ** Emacs can now use HarfBuzz as its shaping engine. The new configure option '--with-harfbuzz' adds support for the  Paul Eggert committed Dec 13, 2018 35 HarfBuzz text shaping engine. It is on by default; use './configure  YAMAMOTO Mitsuharu committed May 05, 2019 36 37 --without-harfbuzz' to build without it. The HarfBuzz text shaping is available via new font backend drivers 'xfthb' and 'ftcrhb' for Xft  Eli Zaretskii committed May 31, 2019 38 and Cairo drawings, respectively, and via the 'harfbuzz' backend on  Eli Zaretskii committed Jun 01, 2019 39 40 41 42 43 MS-Windows. The Harfbuzz text shaping is preferred to the previously supported ones, so the font backends that use older shaping engines (FLT on GNU and Unix systems and Uniscribe on MS-Windows) are not enabled by default; they can be enabled via the 'font-backend' frame parameter or via X resources.  Paul Eggert committed Dec 13, 2018 44   Philipp Stephani committed Dec 10, 2017 45 ** The new configure option '--with-json' adds support for JSON using  Michael Albinus committed Nov 13, 2018 46 the Jansson library. It is on by default; use './configure  Philipp Stephani committed Dec 10, 2017 47 48 49 50 51 --with-json=no' to build without Jansson support. The new JSON functions 'json-serialize', 'json-insert', 'json-parse-string', and 'json-parse-buffer' are typically much faster than their Lisp counterparts from json.el.  Michael Albinus committed Jul 28, 2019 52 ** The configure option '--with-cairo' is no longer experimental.  Paul Eggert committed Jun 19, 2019 53 54 55 This builds Emacs with Cairo drawing, and supports built-in printing when Emacs is built with GTK+.  Paul Eggert committed May 13, 2019 56 57 58 59 ** Emacs no longer defaults to using ImageMagick to display images, due to security and stability concerns. To override the default, use 'configure --with-imagemagick'.  Paul Eggert committed Mar 25, 2019 60 61 ** Several configure options now accept an option-argument 'ifavailable'. For example, './configure --with-xpm=ifavailable' now configures Emacs  Michael Albinus committed May 06, 2019 62 63 64 to attempt to use libxpm but to continue building even if libxpm is absent. The other affected options are '--with-gif', '--with-gnutls', '--with-jpeg', '--with-png', and '--with-tiff'.  Paul Eggert committed Mar 25, 2019 65   Paul Eggert committed Aug 05, 2018 66 67 68 69 70 71 72 ** The etags program now uses the C library's regular expression matcher when possible, and a compatible regex substitute otherwise. This will let developers maintain Emacs's own regex code without having to also support other programs. The new configure option '--without-included-regex' forces etags to use the C library's regex matcher even if the regex substitute ordinarily would be used to work around compatibility problems.  Michael Albinus committed Nov 13, 2018 73 ** Emacs has been ported to the '-fcheck-pointer-bounds' option of GCC.  Paul Eggert committed Dec 12, 2017 74 75 76 77 78 79 This causes Emacs to check bounds of some arrays addressed by its internal pointers, which can be helpful when debugging the Emacs interpreter or modules that it uses. If your platform supports it you can enable it when configuring, e.g., './configure CFLAGS="-g3 -O2 -mmpx -fcheck-pointer-bounds"' on Intel MPX platforms.  Paul Eggert committed Jan 01, 2018 80 81 82 ** Emacs now normally uses a C pointer type instead of a C integer type to implement Lisp_Object, which is the fundamental machine word type internal to the Emacs Lisp interpreter. This change aims to  Michael Albinus committed Nov 13, 2018 83 84 catch typos and supports '-fcheck-pointer-bounds'. The 'configure' option '--enable-check-lisp-object-type' is therefore no longer as  Paul Eggert committed Dec 17, 2017 85 86 87 useful and so is no longer enabled by default in developer builds, to reduce differences between developer and production builds.  Eli Zaretskii committed Jan 16, 2019 88 89 90 91 92 93 94 95 96 97 98 99 100 +++ ** Emacs now uses a "portable dumper" instead of unexec. This improves compatibility with memory allocation on modern systems, and in particular better supports the Address Space Layout Randomization (ASLR) feature, a security technique used by most modern operating systems. When built with the portable dumping support (which is the default), Emacs looks for the 'emacs.pdmp' file, generated during the build, in its data directory at startup, and loads the dumped state from there. The new command-line argument '--dump-file=FILE' allows to specify a non-default '.pdmp' file to load the state from; see the node "Initial Options" in the Emacs manual for more information.  Daniel Colascione committed Jan 15, 2019 101   Paul Eggert committed Jul 23, 2019 102 An Emacs started via a dump file can create a new dump file only if it  Michael Albinus committed Jul 28, 2019 103 was invoked with the '-batch' option.  Paul Eggert committed Jul 23, 2019 104 105 106 107 108 109 110  Although the portable dumper has been tested, it may have a bug on unusual platforms. If you require traditional unexec dumping you can use the configure-time option '--with-dumping=unexec'; however, please file a bug report describing the situation, as unexec dumping is deprecated.  Paul Eggert committed Apr 10, 2019 111 112 113 114 115 +++ ** The new configure option '--enable-checking=structs' attempts to check that the portable dumper code has been updated to match the last change to one of the data structures that it relies on.  Paul Eggert committed Apr 21, 2019 116 +++  Paul Eggert committed Apr 21, 2019 117 118 119 ** The configure options '--enable-checking=conslist' and '--enable-checking=xmallocoverrun' have been withdrawn. The former made Emacs irredeemably slow, and the latter made it crash. Neither  Eli Zaretskii committed Apr 22, 2019 120 121 122 option was useful with modern debugging tools such as AddressSanitizer. (See etc/DEBUG for the details of using the modern replacements of the removed configure options.)  Paul Eggert committed Apr 21, 2019 123   Paul Eggert committed May 16, 2019 124 125 126 127 +++ ** The distribution tarball now has test cases; 'make check' runs them. This is intended mostly to help developers.  Alexander Gramiak committed Apr 14, 2019 128 129 130 131 --- ** Emacs now requires GTK 2.24 and GTK 3.10 for the GTK 2 and GTK 3 builds respectively.  Stefan Kangas committed Aug 29, 2019 132 133 ** New make target 'help' shows a summary of common make targets.  Glenn Morris committed Jan 06, 2016 134   Eli Zaretskii committed Sep 16, 2017 135 * Startup Changes in Emacs 27.1  Eli Zaretskii committed Jul 22, 2017 136   Paul Eggert committed Aug 27, 2019 137 138 +++ ** Emacs now uses the XDG convention for init files.  Eli Zaretskii committed Aug 28, 2019 139 140 141 142 143 144 145 146 147 148 149 150 151 For example, it looks for init.el in ~/.config/emacs/init.el, and similarly for other init files. The XDG_CONFIG_HOME environment variable (which defaults to ~/.config) specifies the parent directory of these and other configuration files, and will override their traditional locations (the home directory, ~/.emacs.d, etc.). Emacs will still look for init files in their traditional locations if XDG_CONFIG_HOME does not exist, so invoking Emacs with XDG_CONFIG_HOME='/nowhere' might be useful if your new-location init files are scrambled, or if you want to force Emacs to ignore files under XDG_CONFIG_HOME for some other reason.  Paul Eggert committed Aug 27, 2019 152   Radon Rosborough committed Feb 17, 2018 153 154 155 156 157 158 159 160 161 +++ ** Emacs can now be configured using an early init file. The file is called 'early-init.el', in 'user-emacs-directory'. It is loaded very early in the startup process: before graphical elements such as the tool bar are initialized, and before the package manager is initialized. The primary purpose is to allow customizing how the package system is initialized given that initialization now happens before loading the regular init file (see below).  Eli Zaretskii committed Jun 12, 2018 162 163 164 165 We recommend against putting any customizations in this file that don't need to be set up before initializing installed add-on packages, because the early init file is read too early into the startup process, and some important parts of the Emacs session, such as  Michael Albinus committed Nov 16, 2018 166 'window-system' and other GUI features, are not yet set up, which could  Eli Zaretskii committed Jun 12, 2018 167 168 make some customization fail to work.  Radon Rosborough committed Feb 17, 2018 169 +++  Stefan Monnier committed Mar 26, 2018 170 ** Installed packages are now activated *before* loading the init file.  Radon Rosborough committed Feb 17, 2018 171 172 173 174 This is part of a change intended to eliminate the behavior of package.el inserting a call to 'package-initialize' into the init file, which was previously done when Emacs was started. As a result of this change, it is no longer necessary to call 'package-initialize'  Stefan Monnier committed Mar 26, 2018 175 176 in your init file.  Michael Albinus committed May 06, 2019 177 178 179 180 181 182 183 184 However, if your init file changes the values of 'package-load-list' or 'package-user-dir', or sets 'package-enable-at-startup' to nil then it won't work right without some adjustment: - You can move that code to the early init file (see above), so those settings apply before Emacs tries to activate the packages. - You can use the new 'package-quickstart' so activation of packages does not need to pay attention to 'package-load-list' or 'package-user-dir' any more.  Radon Rosborough committed Feb 17, 2018 185   Lucas Werkmeister committed Jul 25, 2018 186 187 188 189 190 --- ** Emacs now notifies systemd when startup finishes or shutdown begins. Units that are ordered after 'emacs.service' will only be started after Emacs has finished initialization and is ready for use. (If your Emacs is installed in a non-standard location and you copied the  Michael Albinus committed Nov 13, 2018 191 emacs.service file to eg "~/.config/systemd/user/", you will need to copy  Lucas Werkmeister committed Jul 25, 2018 192 193 the new version of the file again.)  Eli Zaretskii committed Jan 05, 2016 194   Eli Zaretskii committed Sep 16, 2017 195 * Changes in Emacs 27.1  Reuben Thomas committed Aug 30, 2017 196   Glenn Morris committed Nov 13, 2018 197 198 ** emacsclient  Michael Albinus committed Jul 28, 2019 199 200 201 *** emacsclient no longer passes '--eval' arguments to an alternate editor. Previously, '--eval' arguments were passed as file names to any alternate editor started by '--alternate-editor'.  Lars Ingebrigtsen committed Jun 27, 2019 202   Daniel Pittman committed Oct 27, 2018 203 +++  Glenn Morris committed Jul 14, 2019 204 205 206 *** emacsclient now supports an 'EMACS_SOCKET_NAME' environment variable. The command-line argument '--socket-name' overrides it. (The same behavior as for the pre-existing 'EMACS_SERVER_FILE' variable.)  Daniel Pittman committed Oct 27, 2018 207   Paul Eggert committed Dec 01, 2018 208 +++  Michael Albinus committed May 06, 2019 209 *** Emacs and emacsclient now default to "\$XDG_RUNTIME_DIR/emacs"  Paul Eggert committed Dec 01, 2018 210 as the directory for client/server sockets, if Emacs is running  Michael Albinus committed May 06, 2019 211 under an X Window System desktop that sets the 'XDG_RUNTIME_DIR'  Paul Eggert committed Dec 01, 2018 212 environment variable to indicate where session sockets should go.  Paul Eggert committed Dec 06, 2018 213 To get the old, less-secure behavior, you can set the  Michael Albinus committed May 06, 2019 214 'EMACS_SOCKET_NAME' environment variable to an appropriate value.  Paul Eggert committed Dec 01, 2018 215   Glenn Morris committed Nov 13, 2018 216 217 218 219 --- *** When run by root, emacsclient no longer connects to non-root sockets. (Instead you can use Tramp methods to run root commands in a non-root Emacs.)  Robert Pluim committed Jul 16, 2018 220 221 222 ** New function 'network-lookup-address-info'. This does IPv4 and/or IPv6 address lookups on hostnames.  Federico Tedin committed Mar 01, 2019 223 224 225 226 227 228 229 --- ** Control of the threshold for using the 'distant-foreground' color. The threshold for color distance below which the 'distant-foreground' color of the face will be used instead of the foreground color can now be controlled via the new variable 'face-near-same-color-threshold'. The default value is 30000, as the previously hard-coded threshold.  Tino Calancha committed Jul 29, 2018 230 +++  Michael Albinus committed May 06, 2019 231 ** The function 'read-passwd' uses "*" as default character to hide passwords.  Tino Calancha committed Jul 29, 2018 232   Michael Albinus committed May 06, 2019 233 234 235 ** Lexical binding is now used when evaluating interactive Elisp forms. More specifically, lexical-binding is now used for 'M-:', '--eval', as well as in the "*scratch*" and "*ielm*" buffers.  Stefan Monnier committed Apr 25, 2019 236   Eli Zaretskii committed Oct 07, 2017 237 238 239 240 241 242 --- ** The new option 'tooltip-resize-echo-area' avoids truncating tooltip text on GUI frames when tooltips are displayed in the echo area. Instead, it resizes the echo area as needed to accommodate the full tool-tip text.  Martin Rudalics committed Jan 18, 2018 243 ---  Michael Albinus committed Nov 13, 2018 244 ** Show mode line tooltips only if the corresponding action applies.  Martin Rudalics committed Jan 18, 2018 245 246 247 248 Customize the option 'mode-line-default-help-echo' to restore the old behavior where the tooltip text is also shown when the corresponding action does not apply.  Eli Zaretskii committed Mar 10, 2018 249 250 251 252 253 254 255 256 257 +++ ** New hook 'server-after-make-frame-hook'. This hook is a convenient place to perform initializations in daemon mode which require GUI features to be available. One example is restoration of the previous session using the desktop.el package: put the call to 'desktop-read' in this hook, if you want the GUI settings to be restored, or if desktop.el needs to interact with you during restoration of the session.  Lars Ingebrigtsen committed Aug 18, 2019 258 259 260 261 262 +++ ** The functions 'set-frame-height' and 'set-frame-width' are now commands, and will set the currently selected frame to the height/ width specified by the numeric prefix.  Mark Oteiza committed Sep 30, 2017 263 264 265 +++ ** New function 'logcount' calculates an integer's Hamming weight.  Robert Pluim committed Nov 03, 2017 266 267 268 269 270 271 272 273 +++ ** New function 'libxml-available-p'. This function returns non-nil if libxml support is both compiled in and available at run time. Lisp programs should use this function to detect built-in libxml support, instead of testing for that indirectly, e.g., by checking that functions like 'libxml-parse-html-region' return nil.  Lars Ingebrigtsen committed Apr 14, 2018 274 +++  Michael Albinus committed May 06, 2019 275 ** 'libxml-parse-xml-region' and 'libxml-parse-html-region' take  Lars Ingebrigtsen committed Apr 14, 2018 276 277 a parameter that's called DISCARD-COMMENTS, but it really only discards the top-level comment. Therefore this parameter is now  Paul Eggert committed Apr 26, 2018 278 obsolete, and the new utility function 'xml-remove-comments' can be  Lars Ingebrigtsen committed Apr 14, 2018 279 280 281 used to remove comments before calling the libxml functions to parse the data.  Lars Ingebrigtsen committed Jun 24, 2018 282 283 +++ ** The Network Security Manager now allows more fine-grained control  Michael Albinus committed Oct 20, 2018 284 of what checks to run via the 'network-security-protocol-checks'  Lars Ingebrigtsen committed Jun 24, 2018 285 286 variable.  Lars Ingebrigtsen committed Jun 24, 2018 287 +++  Eli Zaretskii committed Jul 08, 2018 288 289 ** TLS connections have their security tightened by default. Most of the checks for outdated, believed-to-be-weak TLS algorithms  Lars Ingebrigtsen committed Aug 23, 2019 290 291 and ciphers are now switched on by default. (In addition, several new TLS weaknesses are now warned about.) By default, the NSM will  Eli Zaretskii committed Jul 08, 2018 292 293 294 295 296 297 flag connections using these weak algorithms and ask users whether to allow them. To get the old behavior back (where certificates are checked for validity, but no warnings about weak cryptography are issued), you can either set 'network-security-protocol-checks' to nil, or adjust the elements in that variable to only happen on the 'high' security level (assuming you use the 'medium' level).  Lars Ingebrigtsen committed Jun 24, 2018 298   Robert Pluim committed Sep 02, 2019 299 300 301 302 303 304 305 306 --- ** New user option 'nsm-trust-local-network'. Allows skipping Network Security Manager checks for hosts on your local subnet(s). It defaults to nil. Usually, there should be no need to set this non-nil, and doing that risks opening your local network connections to attacks. So be sure you know what you are doing before changing the value.  Robert Pluim committed Jan 24, 2019 307 308 309 +++ ** Native GnuTLS connections can now use client certificates.

Marcin Borkowski committed Jan 15, 2018 314 315 316 317 318 +++ ** New function 'fill-polish-nobreak-p', to be used in 'fill-nobreak-predicate'. It blocks line breaking after a one-letter word, also in the case when this word is preceded by a non-space, but non-alphanumeric character.  Noam Postavsky committed Jan 26, 2018 319 320 321 322 323 324 325 +++ ** The limit on repetitions in regexps has been raised to 2^16-1. It was previously limited to 2^15-1.

This command does not notify the VC backend, and is mostly useful for unregistered files.  Juri Linkov committed Jul 25, 2019 784 785 *** New command 'vc-log-search' asks for a pattern, searches it in the revision log, and displays matched log entries in the  Juri Linkov committed Jul 16, 2019 786 787 788 789 790 791 log buffer. For example, 'M-x vc-log-search RET bug#36644 RET' displays all entries whose log messages match the bug number. With a prefix argument asks for a command, so for example, 'C-u M-x vc-log-search RET git log -1 f302475 RET' will display just one log entry found by its revision number.

But if the new option 'comint-insert-previous-argument-from-end' is non-nil, it will copy the Nth argument counting from the last one.

Note, however, that SQL is not like other programming languages like C, Java, or Python where code is sparse and rules for formatting are fairly well established. Instead SQL is more like COBOL (from which it came) and code tends to be very dense and line ending decisions driven by syntax and line length considerations to make readable code. Experienced SQL developers may prefer to rely upon existing Emacs facilities for formatting code but the 'sql-indent' package provides facilities to aid more casual SQL developers layout queries and complex expressions. **** 'sql-use-indent-support' (default t) enables SQL indention support.

When establishing an interactive session with the database via 'sql-connect' or a product specific function, like 'sql-mysql' or 'my-postgres', the password wallet will be searched for the password. The 'sql-product', 'sql-server', 'sql-database', and the 'sql-username' will be used to identify the appropriate authorization.
