+- LFUN_NEXT_INSET_TOGGLE ("next-inset-toggle"): use "inset-toggle" instead.
+- LFUN_NEXT_INSET_MODIFY ("next-inset-modify"): use "inset-modify" instead.
+- LFUN_PARAGRAPH_SPACING ("paragraph-spacing"): use "paragraph-params" instead.
+
+- LFUN_NOTES_MUTATE ("notes-mutate"): replace
+ notes-mutate <SOURCE> <TARGET>
+ with the more general function inset-forall
+ inset-forall Note:<SOURCE> inset-modify note Note <TARGET>
+
+- LFUN_ALL_INSETS_TOGGLE ("all-insets-toggle"): replace
+ all-insets-toggle <ACTION> <TARGET>
+ all-insets-toggle <ACTION>
+ with the more generic function inset-forall
+ inset-forall <TARGET> inset-toggle <ACTION>
+ inset-forall * inset-toggle <ACTION>
+ There is a difference in the <TARGET> parameter, which is would be
+ like "note" in the first case and "Note" in the second.
+
+- LFUN_TABULAR_FEATURE ("tabular-feature"): use "inset-modify" instead.
+ I.e., "tabular-feature FEATURE <ARGS>" becomes:
+ inset-modify tabular FEATURE <ARGS>
+
+- LFUN_LINE_INSERT ("line-insert"): use "inset-insert line" instead. For
+ something close to the previous default, use:
+ inset-insert line rule height 0.25ex width 100col% \\end_inset
+ This is necessary because the line inset now takes various arguments.
+
+- LFUN_TOC_INSERT ("toc-insert"): use "inset-insert toc" instead.
+
+
+The following LyX functions have been changed:
+
+- 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_WORD_REPLACE ("word-replace"): The replacement and searched strings
+ arguments have been inverted in order to allow the replacement of the word
+ at current cursor position, even if it is not selected.
+
+- LFUN_OPTIONAL_INSERT ("optional-insert") has been renamed LFUN_ARGUMENT_INSERT
+ ("argument-insert").
+
+
+The following LyX key bindings have been changed:
+
+- LFUN_MATH_MACRO_FOLD ("math-macro-fold")
+ The binding to "C-minus" has changed to "C-S-underscore".
+
+- LFUN_MATH_MACRO_UNFOLD ("math-macro-unfold")
+ The binding to "C-plus" has changed to "C-S-asterisk".
+
+- On Mac OSX the modifier keys <Control> and <Option> are now treated separately.
+ The distributed key binding for Mac OSX no longer uses the <Option> key for
+ shortcuts with letters or numbers.
+
+ The custom key bindings for <Option>/<Control> are mapped to the <Control>
+ modifier only.
+
+New external programs and libraries:
+------------------------------------
+
+LyX 2.0 introduces support for some new external helper programs/libraries,
+while the support for some existing programs has been dropped. This
+particularly applies to spell checking and the thesaurus.
+
+1.) SPELLCHECKING:
+
+* Direct support for ispell and hspell has been dropped. However, ispell
+ and hspell are still accessible via the enchant wrapper (see below).
+
+* Support for the aspell command line program has been dropped. Note that
+ the aspell library (aspell 0.60.x) is still supported.
+
+* As well as the aspell library, LyX now also supports hunspell (the spell
+ checker used by OpenOffice and Firefox) and enchant, a wrapper that
+ provides automatic access to many spell checking libraries (ispell,
+ aspell, hspell, hunspell, etc.).
+
+* On Mac OSX, Apple's Spell Server is preconfigured as the "native" spell
+ checker.
+
+LyX 2.0 is configured for any and all of these three possibilities,
+given that the various libraries are installed on the machine where LyX is
+configured. The actual spell checker can be selected in Tools > Preferences.
+Packagers are advised to pre-select whatever is most common on their
+platform/distribution.
+
+2.) THESAURUS:
+
+* Support for the aiksaurus library has been dropped in favour of the
+ MyThes thesaurus library (the thesaurus library used by OpenOffice).
+
+* LyX ships the MyThes library itself, so unlike in LyX 1.6.x, no extra
+ thesaurus library needs to be installed. However, LyX does not ship any
+ thesaurus dictionaries, and those do have to be installed separately.
+
+* The OpenOffice thesaurus dictionaries can be used, but the path to those
+ dictionaries needs to be set in Tools > Preferences. Please refer to the
+ UserGuide, sec. 6.14, for further instructions.
+
+Packagers are advised to preset the thesaurus for their distribution/
+platform. Packagers of installation bundles (on Windows and the Mac)
+are advised to provide automatic installation of thesaurus dictionaries
+in the installation process (analoguous to the spellchecker installation).
+
+3.) LILYPOND:
+
+There is now direct support for Lilypond-book. Note that LyX requires at
+least version 2.14 for proper work.
+
+4.) INSTANT PREVIEW:
+
+Make sure that dv2dt (often part of LaTeX distributions) is installed
+on your system. Instant preview wil be disabled if dv2dt is not found.
+
+5.) LuaTeX support
+
+For proper LuaTeX support you need to have at least TeXLive 2010.
