MySQL 5.7 Release Notes
With the introduction of the data dictionary in MySQL 8.0, the
--ignore-db-dir
option and
ignore_db_dirs
system variable
became superfluous and were removed in that version.
Consequently, they are now deprecated in MySQL 5.7.
Incompatible Change:
For STANDALONE
and WIN
builds, the default
secure_file_priv
value has
changed from the empty string to NULL
. This
is a secure-by-default setting because it disables import and
export operations. To permit those operations, set
secure_file_priv
to the path
name of the directory to use for those operations.
(Bug #24679907, Bug #24695274, Bug #24707666)
The linked OpenSSL library for the MySQL Commercial Server has been updated to version 1.0.1u. For a description of issues fixed in this version, see http://www.openssl.org/news/vulnerabilities.html.
This change does not affect the Oracle-produced MySQL Community build of MySQL Server, which uses the yaSSL library instead. (Bug #24753389)
yaSSL was upgraded to version 2.4.2. This upgrade corrects
issues with: Potential AES side channel leaks; DSA padding for
unusual sizes; the
SSL_CTX_load_verify_locations()
OpenSSL
compatibility function failing to handle long path directory
names.
