+* 4.0.4 (October 24, 2015)
+
+  This bugfix release fixes another xallocx() regression.  No other regressions
+  have come to light in over a month, so this is likely a good starting point
+  for people who prefer to wait for "dot one" releases with all the major issues
+  shaken out.
+
+  Bug fixes:
+  - Fix xallocx(..., MALLOCX_ZERO to zero the last full trailing page of large
+    allocations that have been randomly assigned an offset of 0 when
+    --enable-cache-oblivious configure option is enabled.
+
+* 4.0.3 (September 24, 2015)
+
+  This bugfix release continues the trend of xallocx() and heap profiling fixes.
+
+  Bug fixes:
+  - Fix xallocx(..., MALLOCX_ZERO) to zero all trailing bytes of large
+    allocations when --enable-cache-oblivious configure option is enabled.
+  - Fix xallocx(..., MALLOCX_ZERO) to zero trailing bytes of huge allocations
+    when resizing from/to a size class that is not a multiple of the chunk size.
+  - Fix prof_tctx_dump_iter() to filter out nodes that were created after heap
+    profile dumping started.
+  - Work around a potentially bad thread-specific data initialization
+    interaction with NPTL (glibc's pthreads implementation).
+
 * 4.0.2 (September 21, 2015)

  This bugfix release addresses a few bugs specific to heap profiling.

 all files that matches the specified pattern (normally the format of patterns is defined in `glob` manual page
 for your operating system). This option is meaningless for URL includes.
 * `url` (default: **true**) - allow URL includes.
+* `path` (default: empty) - A UCL_ARRAY of directories to search for the include file.
+Search ends after the first patch, unless `glob` is true, then all matches are included.
+* `prefix` (default false) - Put included contents inside an object, instead
+of loading them into the root. If no `key` is provided, one is automatically generated based on each files basename()
+* `key` (default: <empty string>) - Key to load contents of include into. If
+the key already exists, it must be the correct type
+* `target` (default: object) - Specify if the `prefix` `key` should be an
+object or an array.
 * `priority` (default: 0) - specify priority for the include (see below).
+* `duplicate` (default: 'append') - specify policy of duplicates resolving:
+	- `append` - default strategy, if we have new object of higher priority then it replaces old one, if we have new object with less priority it is ignored completely, and if we have two duplicate objects with the same priority then we have a multi-value key (implicit array)
+	- `merge` - if we have object or array, then new keys are merged inside, if we have a plain object then an implicit array is formed (regardeless of priorities)
+	- `error` - create error on duplicate keys and stop parsing
+	- `rewrite` - always rewrite an old value with new one (ignoring priorities)

 Priorities are used by UCL parser to manage the policy of objects rewriting during including other files

+#
+# SYNOPSIS
+#
+#   AX_PROG_LUA[([MINIMUM-VERSION], [TOO-BIG-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_HEADERS[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_LIBS[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_READLINE[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#
+# DESCRIPTION
+#
+#   Detect a Lua interpreter, optionally specifying a minimum and maximum
+#   version number. Set up important Lua paths, such as the directories in
+#   which to install scripts and modules (shared libraries).
+#
+#   Also detect Lua headers and libraries. The Lua version contained in the
+#   header is checked to match the Lua interpreter version exactly. When
+#   searching for Lua libraries, the version number is used as a suffix.
+#   This is done with the goal of supporting multiple Lua installs (5.1,
+#   5.2, and 5.3 side-by-side).
+#
+#   A note on compatibility with previous versions: This file has been
+#   mostly rewritten for serial 18. Most developers should be able to use
+#   these macros without needing to modify configure.ac. Care has been taken
+#   to preserve each macro's behavior, but there are some differences:
+#
+#   1) AX_WITH_LUA is deprecated; it now expands to the exact same thing as
+#   AX_PROG_LUA with no arguments.
+#
+#   2) AX_LUA_HEADERS now checks that the version number defined in lua.h
+#   matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore
+#   unnecessary, so it is deprecated and does not expand to anything.
+#
+#   3) The configure flag --with-lua-suffix no longer exists; the user
+#   should instead specify the LUA precious variable on the command line.
+#   See the AX_PROG_LUA description for details.
+#
+#   Please read the macro descriptions below for more information.
+#
+#   This file was inspired by Andrew Dalke's and James Henstridge's
+#   python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4
+#   (serial 17). Basically, this file is a mash-up of those two files. I
+#   like to think it combines the best of the two!
+#
+#   AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua
+#   paths. Adds precious variable LUA, which may contain the path of the Lua
+#   interpreter. If LUA is blank, the user's path is searched for an
+#   suitable interpreter.
+#
+#   If MINIMUM-VERSION is supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION will be accepted. If
+#   TOO-BIG-VERSION is also supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION and less than
+#   TOO-BIG-VERSION will be accepted.
+#
+#   The Lua version number, LUA_VERSION, is found from the interpreter, and
+#   substituted. LUA_PLATFORM is also found, but not currently supported (no
+#   standard representation).
+#
+#   Finally, the macro finds four paths:
+#
+#     luadir             Directory to install Lua scripts.
+#     pkgluadir          $luadir/$PACKAGE
+#     luaexecdir         Directory to install Lua modules.
+#     pkgluaexecdir      $luaexecdir/$PACKAGE
+#
+#   These paths are found based on $prefix, $exec_prefix, Lua's
+#   package.path, and package.cpath. The first path of package.path
+#   beginning with $prefix is selected as luadir. The first path of
+#   package.cpath beginning with $exec_prefix is used as luaexecdir. This
+#   should work on all reasonable Lua installations. If a path cannot be
+#   determined, a default path is used. Of course, the user can override
+#   these later when invoking make.
+#
+#     luadir             Default: $prefix/share/lua/$LUA_VERSION
+#     luaexecdir         Default: $exec_prefix/lib/lua/$LUA_VERSION
+#
+#   These directories can be used by Automake as install destinations. The
+#   variable name minus 'dir' needs to be used as a prefix to the
+#   appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES.
+#
+#   If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is preformed. If ACTION-IF-NOT-
+#   FOUND is blank, then it will default to printing an error. To prevent
+#   the default behavior, give ':' as an action.
+#
+#   AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_INCLUDE, which
+#   may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If
+#   LUA_INCLUDE is blank, then this macro will attempt to find suitable
+#   flags.
+#
+#   LUA_INCLUDE can be used by Automake to compile Lua modules or
+#   executables with embedded interpreters. The *_CPPFLAGS variables should
+#   be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE).
+#
+#   This macro searches for the header lua.h (and others). The search is
+#   performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE.
+#   If the search is unsuccessful, then some common directories are tried.
+#   If the headers are then found, then LUA_INCLUDE is set accordingly.
+#
+#   The paths automatically searched are:
+#
+#     * /usr/include/luaX.Y
+#     * /usr/include/lua/X.Y
+#     * /usr/include/luaXY
+#     * /usr/local/include/luaX.Y
+#     * /usr/local/include/lua-X.Y
+#     * /usr/local/include/lua/X.Y
+#     * /usr/local/include/luaXY
+#
+#   (Where X.Y is the Lua version number, e.g. 5.1.)
+#
+#   The Lua version number found in the headers is always checked to match
+#   the Lua interpreter's version number. Lua headers with mismatched
+#   version numbers are not accepted.
+#
+#   If headers are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_LIB, which may
+#   contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank,
+#   then this macro will attempt to find suitable flags.
+#
+#   LUA_LIB can be used by Automake to link Lua modules or executables with
+#   embedded interpreters. The *_LIBADD and *_LDADD variables should be used
+#   for this purpose, e.g. mymod_LIBADD = $(LUA_LIB).
+#
+#   This macro searches for the Lua library. More technically, it searches
+#   for a library containing the function lua_load. The search is performed
+#   with a combination of LIBS, LIBRARY_PATH, and LUA_LIB.
+#
+#   If the search determines that some linker flags are missing, then those
+#   flags will be added to LUA_LIB.
+#
+#   If libraries are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_READLINE: Search for readline headers and libraries. Requires the
+#   AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from the
+#   Autoconf Archive.
+#
+#   If a readline compatible library is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is performed.

-The function returns a pointer which holds the state of calculation.
+XXH state space must first be allocated, using either static or dynamic method provided above.

-This pointer must be provided as "void* state" parameter for XXH32_update().
-XXH32_update() can be called as many times as necessary.
-The user must provide a valid (allocated) input.
+Start a new hash by initializing state with a seed, using XXHnn_reset().
+
+Then, feed the hash state by calling XXHnn_update() as many times as necessary.
+Obviously, input must be valid, meaning allocated and read accessible.
 The function returns an error code, with 0 meaning OK, and any other value meaning there is an error.
-Note that "len" is type "int", which means it is limited to 2^31-1. 
-If your data is larger, it is recommended to chunk your data into blocks 
-of size for example 2^30 (1GB) to avoid any "int" overflow issue.

-Finally, you can end the calculation anytime, by using XXH32_digest().
-This function returns the final 32-bits hash.
-You must provide the same "void* state" parameter created by XXH32_init().
-Memory will be freed by XXH32_digest().
+Finally, you can produce a hash anytime, by using XXHnn_digest().
+This function returns the final nn-bits hash.
+You can nonetheless continue feeding the hash state with more input,
+and therefore get some new hashes, by calling again XXHnn_digest().
+
+When you are done, don't forget to free XXH state space, using typically XXHnn_freeState().
