 Change History
 --------------
-2020-08-31 luaotfload v3.15
+2020-12-31 luaotfload v3.16
+
+    *  The fontloader has been synced with the context code from 2020-12-30
+    *  The entry point is called luaotfload.lua instead of
+       luaotfload-main.lua (but the old name is still provided for 
+       compatibility).
+    *  pre/post_shaping_filter callbacks has been added.
+    *  The number of lua-files and submodules shown in the log-file 
+       has been reduced. But it is extended again by setting the environment 
+       variable LUAOTFLOAD_TRACE_SUBMODULES=1.
+    *  The HarfBuzz based shaper will in some situations drop hyphenation
+       points. This happens less frequently now since the new version uses
+       first/second discretionaries (the mechanism described in the LuaTeX manual,
+       section 5.6 for the of-f-ice example) to support a limited amount of
+       nesting.
+    *  When the node shaper is used, experimental support for 
+       OpenType variable fonts has been added. To use them, set the font 
+       feature axis to a comma separated list of axis names and values. 
+       (E.g.  axis={weight=600}) The supported axis names and value 
+       range depend on the font.
+    *  The font features upper and lower can be used to map
+       the text of a font to upper or lowercase before displaying it. Currently
+       this implements the untailored Unicode case mapping algorithm, but it is
+       planned to add tailoring later.
+    *  A number of small bugfixes.
+
+2020-09-02 luaotfload v3.15
     * The font database is updated more reliably if fonts get deleted.
     * In multiple error cases, error messages are shown instead of silently
       generating bad output.

-    This file initializes the system and loads the font loader. To
-    minimize potential conflicts between other packages and the code
-    imported from \CONTEXT, several precautions are in order. Some of
-    the functionality that the font loader expects to be present, like
-    raw access to callbacks, are assumed to have been disabled by
-    \identifier{luatexbase} when this file is processed. In some cases
-    it is possible to trick it by putting dummies into place and
-    restoring the behavior from \identifier{luatexbase} after
-    initilization. Other cases such as attribute allocation require
-    that we hook the functionality from \identifier{luatexbase} into
-    locations where they normally wouldn’t be.
-
-    Anyways we can import the code base without modifications, which is
-    due mostly to the extra effort by Hans Hagen to make \LUATEX-Fonts
-    self-contained and encapsulate it, and especially due to his
-    willingness to incorporate our suggestions.

+\beginsubsection {New in version 3.16 (by Ulrike Fischer/Marcel Krüger)}
+\begin{itemize}
+  \item The entry point is called \identifier{luaotfload.lua} instead of
+     \identifier{luaotfload-main.lua} (but the old name is still provided for compatibility).
+  \item  \inlinecode{pre/post_shaping_filter} callbacks has been added.
+  \item  The number of \abbrev{lua}-files and submodules shown in the \abbrev{log}-file has been reduced. But it
+   is extended again by setting the environment variable \inlinecode{LUAOTFLOAD_TRACE_SUBMODULES=1}.
+  \item The HarfBuzz based shaper will in some situations drop hyphenation
+   points. This happens less frequently now since the new version uses
+   first/second discretionaries (the mechanism described in the LuaTeX manual,
+   section 5.6 for the of-f-ice example) to support a limited amount of
+   nesting.
+  \item When the \texttt{node} shaper is used, experimental support for OpenType variable
+   fonts has been added. To use them, set the font feature \texttt{axis} to
+   a comma separated list of axis names and values. (E.g.  \texttt{axis={weight=600}})
+   The supported axis names and value range depend on the font (see~page~\pageref{variablefonts}).
+ \item The font features \texttt{upper} and \texttt{lower} can be used to map
+   the text of a font to upper or lowercase before displaying it. Currently
+   this implements the untailored Unicode case mapping algorithm, but it is
+   planned to add tailoring later (see~page~\pageref{upperlower}).
+  \item A number of small bugfixes.

+
+    This file initializes the system and loads the font loader. To
+    minimize potential conflicts between other packages and the code
+    imported from \CONTEXT, several precautions are in order. Some of
+    the functionality that the font loader expects to be present, like
+    raw access to callbacks, are assumed to have been disabled by
+    \identifier{luatexbase} when this file is processed. In some cases
+    it is possible to trick it by putting dummies into place and
+    restoring the behavior from \identifier{luatexbase} after
+    initilization. Other cases such as attribute allocation require
+    that we hook the functionality from \identifier{luatexbase} into
+    locations where they normally wouldn’t be.
+
+    Anyways we can import the code base without modifications, which is
+    due mostly to the extra effort by Hans Hagen to make \LUATEX-Fonts
+    self-contained and encapsulate it, and especially due to his
+    willingness to incorporate our suggestions.
