D.7.1. Alterações na distribuição 3.20.18

  • Added -p# (remove # directories from path) to isamlog. All files are written with a relative path from the database directory Now mysqld shouldn't crash on shutdown when using the --log-isam option.

  • New mysqlperl version. It is now compatible with msqlperl-0.63.

  • New DBD module available.

  • Added group function STD() (standard deviation).

  • The mysqld server is now compiled by default without debugging information. This will make the daemon smaller and faster.

  • Now one usually only has to specify the --basedir option to mysqld. All other paths are relative in a normal installation.

  • BLOB columns sometimes contained garbage when used with a SELECT on more than one table and ORDER BY.

  • Fixed that calculations that are not in GROUP BY work as expected (SQL-99 extension). Example: 

    mysql> SELECT id,id+1 FROM table GROUP BY id;

  • The test of using MYSQL_PWD was reversed. Now MYSQL_PWD is enabled as default in the default release.

  • Fixed conversion bug which caused mysqld to core dump with Arithmetic error on SPARC-386.

  • Added --unbuffered option to mysql, for new mysqlaccess.

  • When using overlapping (unnecessary) keys and join over many tables, the optimiser could get confused and return 0 records.
