The MySQL Community Server 8.2.0 builds are prepared for all major distributions of Linux, FreeBSD, macOS, and Windows.    <\/p>\n<p>MySQL 8.2.0 is the second release that has been developed under the new release model, featuring two types of MySQL branches \u2014 'Innovation' and 'LTS'. The Innovation branches, which include MySQL 8.1 and 8.2, are recommended for those who want early access to new features. These branches are published every 3 months and are supported only until the release of the next significant version (for example, support for branch 8.1 ends after the release of branch 8.2). The LTS branches are recommended for deployments that require predictability and a long-lasting unchanged behavior. LTS branches will be released every two years and will be supported in the regular mode for 5 years, with an option for an additional 3 years of extended support. The LTS release of MySQL 8.4 is expected in the spring of 2024, after which a new Innovation branch 9.0 will be formed.      <\/p>\n<p>Key changes in MySQL 8.2:  <\/p>\n<ul>\n<li class=\"l\"> Support for the Webauthn (FIDO2) authentication mechanism has been added, enabling multi-factor authentication and passwordless connections to <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-shicago\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2927\">server<\/a> MySQL using FIDO2-compliant hardware tokens or biometric authentication. The Webauthn support plugin is currently available only for MySQL Enterprise.\n<li class=\"l\"> The mysql_native_password server plugin, which provides authentication using passwords, has been moved to an optional category and can be disabled. Instead of mysql_native_password, it is recommended to switch to using the caching_sha2_password plugin, which uses the SHA2 algorithm for hashing instead of SHA1. To switch users to the caching_sha2_password plugin while replacing the password with a random one, the following command can be used:       ALTER USER 'username'@'localhost'     IDENTIFIED WITH caching_sha2_password BY RANDOM PASSWORD     PASSWORD EXPIRE     FAILED_LOGIN_ATTEMPTS 3 PASSWORD_LOCK_TIME 2;\n<li class=\"l\"> Optimization of hash tables has been carried out, allowing faster execution of EXCEPT and INTERSECT operations.\n<li class=\"l\"> Debugging capabilities have been expanded. The SELECT, INSERT, REPLACE, UPDATE, and DELETE operations now support the expression 'EXPLAIN FORMAT=JSON' to generate diagnostic output in JSON format (for example, 'EXPLAIN FORMAT=JSON INTO @var select_stmt;').\n<li class=\"l\"> An 'EXPLAIN FOR SCHEMA' statement has been added for diagnostics related specifically to a certain data schema.\n<li class=\"l\"> The mysqldump utility has been updated with the '--output-as-version' option to create dumps compatible with a specific older version of MySQL (for example, you can specify BEFORE_8_2_0 or BEFORE_8_0_23 to revert to the non-politically correct terminology master\/slave, which has been deprecated in versions 8.2.0 and 8.0.23).\n<li class=\"l\"> The client C library has been updated to include the use of named attributes in parameterized queries (prepared statements) implemented through the new function mysql_stmt_bind_named_param(), replacing the function mysql_stmt_bind_param().\n<li class=\"l\"> SQL traffic distribution in the MySQL server cluster has been simplified. Capabilities have been provided to organize transparent connections for applications to secondary or primary servers.\n<li class=\"l\"> A new privilege SET_ANY_DEFINER has been added, granting the right to create objects with the DEFINER expression, as well as the privilege ALLOW_NONEXISTENT_DEFINER to protect objects without an owner.\n<li class=\"l\"> The following have been deprecated: the old and new variables, the masks '%' and '_' in database access granting operations, the '--character-set-client-handshake' option, the binlog_transaction_dependency_tracking variable, and the SET_USER_ID privilege.\n<li class=\"l\"> In the context of updating politically incorrect terminology related to replication, the phrases \"RESET MASTER\", \"SHOW MASTER STATUS\", \"SHOW MASTER LOGS\" and \"PURGE MASTER LOGS\" have been deprecated, and should now be replaced with the phrases \"RESET BINARY LOGS AND GTIDS\", \"SHOW BINARY LOG STATUS\", \"SHOW BINARY LOGS\" and \"PURGE BINARY LOGS\".\n<li class=\"l\"> Deprecated features have been removed: the function WAIT_UNTIL_SQL_THREAD_AFTER_GTIDS(), the variable expire_logs_days, and the options \"--abort-slave-event-count\" and \"--disconnect-slave-event-count\".\n<li class=\"l\"> 26 vulnerabilities have been resolved. Two vulnerabilities related to the use of the Curl package and the OpenSSL library may be exploited remotely.      <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=59995\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Oracle \u0441\u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043b\u0430 \u043d\u043e\u0432\u0443\u044e \u0432\u0435\u0442\u043a\u0443 \u0421\u0423\u0411\u0414 MySQL 8.2 \u0438 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b\u0430 \u043a\u043e\u0440\u0440\u0435\u043a\u0442\u0438\u0440\u0443\u044e\u0449\u0438\u0435 \u043e\u0431\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u044f MySQL 8.0.35 \u0438 5.7.44. \u0421\u0431\u043e\u0440\u043a\u0438 MySQL Community Server 8.2.0 \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d\u044b \u0434\u043b\u044f \u0432\u0441\u0435\u0445 \u043e\u0441\u043d\u043e\u0432\u043d\u044b\u0445 \u0434\u0438\u0441\u0442\u0440\u0438\u0431\u0443\u0442\u0438\u0432\u043e\u0432 Linux, FreeBSD, macOS \u0438 Windows.
