For twenty years a MySQL version number carried that promise, and you could plan by reading it. With the move to calendar-style releases the number tells you one thing: when it was built. The promise moved elsewhere, and you have to know where to look.</p> <p>The signals now are the channel and the dates. Is this an LTS or an innovation release. When does support end. What do the compatibility notes actually say, because &ldquo;no major version&rdquo; does not mean &ldquo;no behavior change&rdquo;. Optimizer changes ship in any release. Your query plans do not read version numbers.</p> https://useinov.com/posts/2024/mysql-lts/ Tue, 30 Apr 2024 21:05:00 +0300 https://useinov.com/posts/2024/mysql-lts/ <p>Half the industry is sitting on MySQL 5.7 right now, unsupported since last autumn, and calling it stability.</p> <p>MySQL 8.4 came out today, and the important word in the announcement is not a feature. It is LTS. First long-term release of the new model: innovation releases every quarter for the brave, an LTS every couple of years for production, bugfixes only after that.</p> <p>People underestimate how much pain the old model caused. 8.0 was a rolling target. A &ldquo;minor&rdquo; 8.0.x could change optimizer behavior or deprecate something you used. Staying current meant re-testing, staying behind meant missing security fixes.</p>
