-Changes in version 1.7:
+Changes in version 1.8:
 
-When compressing on a 32 bit system, plzip now tries to limit the memory
-use to under 2.22 GiB (4 worker threads at level -9) by reducing the
-number of threads below the system's default.
+The new options '--in-slots' and '--out-slots', setting the number of input
+and output packets buffered during streamed decompression, have been added.
+Increasing the number of packets may increase decompression speed, but
+requires more memory.
 
-The option '--loose-trailing', has been added.
+The default number of input packets buffered per worker thread when
+decompressing from non-seekable input has been increased from 2 to 4.
 
-The test used by plzip to discriminate trailing data from a corrupt
-header in multimember regular (seekable) files has been improved to a
-Hamming distance (HD) of 3, and the 3 bit flips must happen in different
-magic bytes for the test to fail. As a consequence some kinds of files
-no longer can be appended to a lzip file as trailing data unless the
-'--loose-trailing' option is used when decompressing.
-Lzlib 1.10 or newer is required for this test to work on non-seekable
-files.
-Lziprecover can be used to remove conflicting trailing data from a file.
+The default number of output packets buffered per worker thread when
+decompressing to non-seekable output has been increased from 32 to 64.
 
-The 'bits/byte' ratio has been replaced with the inverse compression
-ratio in the output.
+Detection of forbidden combinations of characters in trailing data has been
+improved.
 
-The progress of decompression is now shown at verbosity level 2 (-vv) or
-higher.
+Errors are now also checked when closing the input file.
 
-Progress of (de)compression is only shown if stderr is a terminal.
+The descriptions of '-0..-9', '-m' and '-s' in the manual have been
+improved.
 
-A second '.lz' extension is no longer added to the argument of '-o' if
-it already ends in '.lz' or '.tlz'.
+The configure script now accepts the option '--with-mingw' to enable the
+compilation of plzip under MS Windows (with the MinGW compiler). Use with
+care. The Windows I/O functions used are not guaranteed to be thread safe.
+(Code based on a patch by Hannes Domani).
 
-The dictionary size is now shown at verbosity level 4 (-vvvv) when
-decompressing or testing.
+The configure script now accepts appending options to CXXFLAGS using the
+syntax 'CXXFLAGS+=OPTIONS'.
 
-The new chapter "Meaning of plzip's output", and a block diagram of
-plzip have been added to the manual.
+It has been documented in INSTALL the use of
+CXXFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW.
