Breaking changes

This release should not break existing code.

Bugfixes

• <connection object>:reset() now raise an error at failure to change a user
  (PR #43).

  Also this method was missed in the documentation and added now.

• Fixed connections accounting in the connection pool (#33, PR #42).

  <connection object>:close() on a connection from the pool now returns it to the pool.

  <pool object>:close() now closes all connections originated from the pool.

  Attempt to call <pool object>:put(<connection object>) on a connection that is already put in the pool now returns an error.

  <connection object>:close() and <pool object>:close() were missed in the documentation and added now.

• Prevent possible deadlock in the case, when the pool is used from different fibers (#34, PR #55).

• <connection object>:close() now returns true instead of 1 (PR #42).

New features

• Added use_numeric_result = <boolean> option to mysql.connect() and mysql.pool_create() to choose a shape of the <connection object>:execute() result (PR #25).

  Default (false) is the old behaviour, where rows are <column name> = <value> mappings. When the option is set to true, the rows are just arrays of values and columns metatada is returned separately.

• Added timeout = <number> option to <pool object>:get() (PR #28).

• Added keep_null = <boolean> option to mysql.connect() and mysql.pool_create() to choose whether NULL values will be encoded as nil or box.NULL in a <connection object>:execute() result (PR #8).

  Default (false) is the old behaviour: nil. When the option is set to true, box.NULL is used.

Build

• Fixed RPM package build for CentOS 6 (#53, PR #).
• Fixed build with CMake 3.20+ (#59, PR #60).
• Use git+https// protocol in the rockspec (PR #62).
