+	* Version 1.12 released.
+	* lzlib.h: Define LZ_API_VERSION as 1000 * major + minor. 1.12 = 1012.
+	  This change does not affect the soversion.
+	* lzlib.h, lzlib.c: New function LZ_api_version.
+	* LZd_try_verify_trailer: Return 2 if EOF at trailer or EOS marker.
+	* Decompression speed has been slightly increased.
+	* decoder.h: Increase 'rd_min_available_bytes' from 8 to 10.
+	* encoder_base.c (LZeb_try_sync_flush):
+	  Compensate for the increase in 'rd_min_available_bytes'.
+	* main.c (do_decompress): Fix false report about library stall.
+	* main.c: New option '--check-lib'.
+	* main.c (main): Report an error if a file name is empty.
+	  Make '-o' behave like '-c', but writing to file instead of stdout.
+	  Make '-c' and '-o' check whether the output is a terminal only once.
+	  Do not open output if input is a terminal.
+	  Replace 'decompressed', 'compressed' with 'out', 'in' in output.
+	  Set a valid invocation_name even if argc == 0.
+	* lzlib.texi: Document the new way of verifying the library version.
+          Document that 'LZ_(de)compress_close' and 'LZ_(de)compress_errno'
+          can be called with a null argument.
+	  Document that sync flush marker is not allowed in lzip files.
+	  Document the consequences of not calling 'LZ_decompress_finish'.
+	  Document that 'LZ_decompress_read' returns at least once per member.
+	  Document that 'LZ_(de)compress_read' can be called with a null
+	  buffer pointer argument.
+	  Real code examples for common uses have been added to the tutorial.
+	* bbexample.c: Don't use 'LZ_(de)compress_write_size'.
+	* lzcheck.c: New options '-s' (sync) and '-m' (member by member).
+	  Test member by member without 'LZ_decompress_finish'.
+	* ffexample.c: New file containing example functions for file-to-file
+	  compression/decompression.
+	* Document extraction from tar.lz in '--help' output and man page.
+	* Makefile.in: 'install-bin' no longer installs the man page.
+	  New targets 'install-bin-compress' and 'install-bin-strip-compress'.
+	* testsuite: Add 9 new test files.
