+2017.118: 2.19.4
+	- Add global LM_SIZEOF_OFF_T variable that is set to the size of
+	the off_t data type as determined at compile time.
+
+2017.075: 2.19.3
+	- Add missing public, global symbols to libmseed.map, thanks
+	to Elliott Sales de Andrade.
+
+2017.061: 2.19.2
+	- Provide install target in Makefile thanks to by Pierre Duperray.
+	- Deprecate dynamic build target, the shared target will now build
+	shared or dynamic (Darwin) libraries depending on the system.
+	- Limit symbols exported in shared libraries to public interfaces
+	as defined in libmseed.map, thanks again to Pierre Duperray.
+	- Allow tests to work on Darwin with dynamic libraries.
+
+2017.060: 2.19.1
+	- Derive versioning of shared/dynamic library from canonical version
+	defined as LIBMSEED_VERSION in libmseed.h.
+	- Apply updates to more standardized use of NAME and typos in man pages,
+	submitted by Pierre Duperray.
+
+2017.053: 2.19
+	- Incorporate lmplatform.h details into libmseed.h for improved usage.
+	All that is needed is the static/shared/dynamic library and libmseed.h.
+	- Avoid undefined left shifts of signed values that would go out of
+	range and specify the types of some constants.
+
+2016.290:
+	- Remove dependency on ntwin32.mak for Windows nmake makefiles, now
+	building works in plain MSVC development environments.
+
+2016.286: 2.18
+	- Remove limitation on sample rate before calling ms_genfactmult()
+	in the normal path of packing records.  Previously generating the
+	factor and multiplier was not attempted for rates higher than
+	32,767.
+
+2016.281: 2.18rc4
+	- ms_genfactmult() now support a much larger range of integer
+	sample rates and periods.
+	- ms_genfactmult() now sets the factor and multiplier using the
+	SECONDS/SAMPLE notation for sample rates less than 1.0 to retain
+	precision for low rates.
+	- ms_genfactmult() now assumes the specified rate is a sample
+	period in seconds if the samprate value is negative.
+	- Add ms_rsqrt64() as a general use reciprocal sqrt for doubles.
+	- Use memcpy() instead of assignment when unpacking float32 and
+	float64 samples to avoid problems with NaN's.  Thanks Lion Krischer.
+	- Add test for reading records without Blockette 1000.
+	- Reformat all source code using included clang-format profile.
+
+2016.277:
+	- A more elegant sanity check for output length in packing by mbyt.
+
+2016:276: 2.18rc3
+	- Improvements for test suite, more consistency.
+	- Remove msr_decode_steim? from libmseed.def, they are internal.
+	- Add sanity to length check before memset calls in packing functions.
+
+2016:274: 2.18rc2
+	- Check for environment variables ENCODE_DEBUG and DECODE_DEBUG
+	and set debugging output, at this point it is Steim frame details
+	and differences being encoded/decoded.
+	- Fix padding in steim[12] encoding routines.
+	- Remove unneeded output buffer checks in steim[12] decoding routines.
+
+2016.272: 2.18rc1
+	- Replace data sample packing and unpacking routines from qlib2 with
+	new routines developed from scratch.  All code is now LGPL licensed.
+	- Add test suite with tests for encoding, decoding, parsing, etc.
+	- Update licensing to GNU-LGPL version 3 and include (L)GPL licenses
+	in LICENSE.txt.
+
+2015.053:
+	- Define needed C99 int types for MSVC 2012 or earlier.  Previously
+	this was only done for versions earlier than MSVC 2010.
+
+2015.213: 2.17
+	- Round Fixed Section Data Header start time values to the nearest
+	tenth of millisecond and restrict the microsecond offset value
+	to a range between -50 and +49 as recommended in SEED.  Previously
+	start times were truncated at tenths of millisecond resolution
+	and the microsecond offset value was between 0 and +99.  This also
+	addresses a bug where microsecond offsets were off by 100ms for times
+	before Jan 1 1970.  Thanks to Lion Krischer for reporting.
+
+	Note to future hackers: the definition of HPTMODULUS governing the
+	time tick interval for high precision time values implies that this
+	tick interval may be changed.  In reality, this should not be changed
+	from the default, microsecond tick value without thorough testing.
+	Some logic is know to be dependent on the microsecond tick.
+
+2015.134: 2.16m
+	- Add defines for needed integer types and macros from inttypes.h
+	missing in older MSVC versions.  MSVC 2010 and later appear to have
+	enough C99 support.
+	- Add define tests for _WIN32 and _WIN64 to cover all WINs.
+	- ms_fread(): Add cast to quiet warning for conversion from size_t
+	to int.  In this case the read will always be <= MAXRECLEN, much
+	smaller than int, making the conversion safe.
+
+2015.113: 2.16
+	- Update minor release version in Makefile.
+
+2015.108:
+	- Cleanup of lmplatform.h removing unneeded headers and using C99
+	standard headers except for a few platform specific cases.
+	- Convert all printf() and scanf() usage of %lld for 64-bit integers
+	to use the C99 PRId64 and SCNd64 macros for portability (MinGW).
+	- Change detection of Linux/Cygwin to set global define LMP_LINUX
+	instead of LMP_GLIB2 (now marked as deprecated).
+	- Change detection of Windows to set global define LMP_WIN instead
+	of LMP_WIN32 (now marked as deprecated).
+	- Add detection of __MINGW64__ define.
+	- Tested building on Win7 with: Open Watcom 1.9, MinGW gcc 4.8.1 and
+	Cygwin 1.7.35 (gcc 2.9.2).
+
+2015.074:
+	- Define NTP-Posix time epoch conversion constant specifically as
+	a long long integer to avoid warnings on some compilers.
+
+2015.070: 2.15
+	- Fix infinite loop if blockette chain is corrupt.  Patch submitted
+	by Elliott Sales de Andrade.
+
 2015.062: 2.14
 	- Fix memory leak when msr_pack() returns after an error. Patch
 	contributed by Larry Baker and Eric Thomas.

+
+The library requires that C99 integer types are available on the
+target computer.  Specifically the int8_t, int16_t, int32_t, int64_t
+and their unsigned counterpart types.
+
+## Unix, Linux, macOS
+
+A simple 'make' on most Unix-like systems should build the library.
+
+The included Makefile should work for most Unix-like environments and
+most make variants. It is know to work with GNU make, which, if not the
+default, is sometimes installed as gmake.
+
+The CC, CFLAGS, LDFLAGS and CPPFLAGS environment variables can be set
+to control the build.
+
+By default a statically linked version of the library is built: 'libmseed.a'.
+
+With GCC, clang or compatible build tools it is possible to build a shared
+library with 'make shared'.
+
+A simple install method for the shared library can be invoked with
+'make install'.  By default the installation destination is /usr/local.
+The install destination may be specified using the PREFIX variable, for
+example:
+
+make install PREFIX=/path/to/install/
+
+## Windows (Win32)
+
+On a WIN32 platform the library can be compiled by using the
+Nmake compatible Makefile.win (e.g. 'nmake -f Makefile.win') or Open
+Watcom's Wmake with Makefile.wat (e.g. 'wmake -f Makefile.wat'). The
+default target is a static library 'libmseed.lib'.  The library has
+been tested with Open Watcom 1.8.  A libmseed.def file is included
+for use building and linking a DLL.
