| 15 | - let again gzread copy uncompressed data unchanged (was working in 0.71) | 14 | To install in a different directory, use for example: make install prefix=$HOME |
| 16 | - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented | 15 | This will install in $HOME/lib instead of /usr/local/lib. |
