-This file lists interface changes that might affect users in 1.5.0 and
-also some known problems in LyX 1.5.0 that did not occur in
-1.4.5. Note that fixes are available for many of these, but they have
-not yet been applied because of incomplete testing.
+This file lists interface changes that might affect users in 2.1.0, some
+known problems in LyX 2.1.0 and some things you have to take into account
+when upgrading from earlier versions to a version of the 2.1.x series.
Interface changes
-----------------
-Some of the LyX functions have changed names :
+Whenever the user closes a (tabbed) view on a document, either by
+clicking on the tab close button, or by using the File->Close menu,
+LyX now closes exclusively that specific view. If there are other
+views showing the same document, they are not closed. When the user
+closes the last view, LyX can be configured for either closing the
+document, or keeping it into memory as a hidden document (that can be
+shown again through the View->Hidden-> submenu).
+A new configurable preference option has been added, allowing for either
+(close_buffer_with_last_view)
-Known issues with version 1.5.0
+There have been some changes to the LyX command line. The following new
+options have been added:
+
+-export-to <format> <dest> (-E <format> <dest>)
+
+ Allows one to perform a batch export of the LyX file that is opened
+ to the specified destination file <dest> and format <format>.
+ For example, to create a PDF of a LyX document, you can run:
+ lyx -export-to pdf /path/to/dest.pdf /path/to/source.lyx
+ See the manual page for details.
+ This functionality is also available via a new menu voice
+ Export->Export As..., that pops up a dialog allowing one to
+ choose the export format, as well as the destination pathname.
+ Also, it is available via the mini-buffer (or the -x switch)
+ through a proper new LFUN (see below).
+
+The Advanced Find and Replace feature now supports cancel of a long
+search operation by hitting the ESC key.
+
+The following pref variables were changed in 2.1:
+
+- \\close_buffer_with_last_view [yes|no|ask]
+ When user closes the last view on a document, close the document
+ as well ("yes"), or hide the document ("no"), or ask the user
+ ("ask").
+
+The following pref variables are obsoleted in 2.1:
+
+- \\default_language
+- \\default_papersize
+
+To set the default language and paper size for new documents, use the
+"Save As Document Defaults" button in Document > Settings.
+
+The support for ArmTeX (a special typesetting engine for Armenian) was removed.
+Writing text in Armenian is now possible in a native way using XeTeX.
+
+The following new LyX functions have been introduced:
+
+- LFUN_BRANCH_MASTER_ACTIVATE <branch>:
+ LFUN_BRANCH_MASTER_DEACTIVATE <branch>:
+ Activates or deactivates a branch in a master document from within
+ a child (as opposed to the existing LFUN_BRANCH_[DE]ACTIVATE, which
+ toggle the branch in the document itself).
+
+- LFUN_BUFFER_EXPORT_AS <format> <filename>
+ Equivalent to the new -export-to command-line switch (see above).
+
+- LFUN_CLIPBOARD_PASTE_SIMPLE ("clipboard-paste-simple")
+ Paste the clipboard contents as simple unformatted text.
+ This is also available through a new menu voice within the
+ [Edit]->[Paste Special...] sub-menu.
+
+- LFUN_VIEW_CLOSE
+ Close the current document view only, if there are no more views
+ on the document, either close or hide it (see the new preference
+ option \\close_buffer_with_last_view)
+
+The following LyX functions have been removed:
+
+//template, remove this entry later on
+- LFUN_NEXT_INSET_TOGGLE ("next-inset-toggle"): use "inset-toggle" instead.
+
+
+The following LyX functions have been changed:
+
+//template, remove this entry later on
+- LFUN_INSET_TOGGLE ("inset-toggle"): For some insets, this function was used
+ to show the settings dialog. This is no longer possible and one should use
+ inset-settings for this purpose.
+
+- LFUN_CLOSE_TAB_GROUP_CLOSE ("close-tab-group") was renamed to
+ LFUN_TAB_GROUP_CLOSE ("tab-group-close").
+
+- LFUN_SPIT_VIEW ("split-view") was renamed to
+ LFUN_VIEW_SPLIT ("view-split").
+
+- LFUN_BREAK_PARAGRAPH ("break-paragraph") was renamed to
+ LFUN_PARAGRAPH_BREAK ("paragraph-break").
+
+The following LyX key bindings have been changed:
+
+//template, remove this entry later on
+- LFUN_MATH_MACRO_FOLD ("math-macro-fold")
+ The binding to "C-minus" has changed to "C-S-underscore".
+
+- The binding "C-w" was moved from "buffer-close" to "view-close"
+ (only in cua.bind).
+
+
+Linux desktop file specification and scalable icon has been included
+into the tarball.
+
+
+New external programs and libraries:
------------------------------------
-- User layout files must be converted to UTF-8
-
-In previous version, layout styles were allowed to use non-ASCII names
-using the local encodings. LyX-1.5 now assumes that all layout files are
-UTF-8 encoded. This means that non-ASCII style names are still allowed
-but they nust be valid UTF-8 strings. One way of doing the conversion
-is to use iconv. Using bash, the script below should work:\r
-\r
-cd /path/to/layouts\r
-for l in *\r
-do\r
- cp $l tmp.txt\r
- iconv -f latin1 -t utf8 tmp.txt -o $l\r
-done
-rm tmp.txt
-
-- Cursor restoration problems with Multiple-View
-
-When using multiple Windows to edit different parts of the
-same document, the cursor position is sometimes not correctly restored
-when you switch from one view to the other.
-
-- Languages/encodings and insets
-
-One of the bugs fixed in LyX 1.5.0 is that previously, there were certain
-specific cases in which the LaTeX generated did not correctly reflect
-language/encoding transitions in and around insets (footnotes, LyX notes).
-After much deliberation, it was decided not to change older files such that
-they will still reflect the old LaTeX output; rather, they will now correctly
-reflect the situation as it appears in the GUI. This means, however, that if
-you mangled the text in the GUI in the older versions, in order that it
-generate the correct LaTeX output, the LaTeX will now generate the mangled
-text. If this is problematic for you, please get in touch with us on the
-developers mailing list, we do have some possible solutions for this.
-
-The effects of this will be more pronounced for RTL (Hebrew, Arabic, Farsi)
-users --- though they affect users of other languages as well.
-
-
-Note: There may later be an updated list of known issues online at
- http://wiki.lyx.org/LyX/ReleaseNotes
+- LyX links now against libmagic (http://www.darwinsys.com/file/) if it is
+ available at compile time. This improves the file format detection of
+ included graphics and other files. The old builtin format detection code
+ is used if libmagic is not available.
+
+
+Known issues in version 2.1.0
+-----------------------------
+
+- LyX needs to be run under Python 2 and will not work properly on systems
+ where Python 3 is the default binary. See bug #7030 to know how to fix
+ this properly, since simple sheebang conversion in *.py files will not
+ be enough.
+
+Caveats when upgrading from earlier versions to 2.1.x
+-------------------------------------------------------
+
+In order to improve reported scrolling slowness, we changed the way screen
+painting is done. This, however, can slow down the performance on remote
+X connections and we provide RC_USE_QIMAGE variable, which brings back
+the old way of painting (when set to false).
