Upstream MySQL published an out-of-schedule release this week with two high-severity CVE fixes. We’ve pulled those fixes into our next builds and are skipping the two versions we had already queued: Percona Server for MySQL 8.4.9 and 9.7.0.

These fixes arrived through Oracle’s new monthly Critical Security Patch Updates (CSPUs), which Oracle announced begin May 28, 2026. CSPUs ship targeted high-severity fixes between Oracle’s quarterly Critical Patch Updates. For MySQL, these updates are issued as needed rather than on a fixed monthly schedule, so out-of-schedule security fixes like these may become more common.

We’ve handled a skip like this before. When MySQL Community Server 8.4.2 followed 8.4.1 by only a few weeks, we skipped 8.4.1 and shipped its contents in 8.4.2-2. This is the same …

One of the key themes of the MySQL Community over the past year has been increasing transparency, participation, and collaboration.  Through Public Discussions, Design Proposals, the MySQL Developer Guide, GitHub collaboration, and the MySQL Contributor Summit, we have been working to create more opportunities for the community to engage with the future direction of MySQL.  […]

As part of our ongoing MySQL Community engagement series, we are pleased to invite you to Public Discussion #5, taking place on July 15, 2026, at 7:00 AM PT. Over the past several months, these public discussions have helped us continue the conversation around MySQL Community Edition, roadmap transparency, contribution paths, GitHub collaboration, and ways […]

MySQL Enterprise Edition includes powerful audit filtering capabilities, but writing audit filter JSON by hand can be tedious and error-prone. The JSON model is flexible, which is exactly what makes it useful, but it also means that a small typo, a missing event class, or an incorrectly assigned user can change what does or does […]

For over 30 years, MySQL has grown through the contributions, feedback, and collaboration of a global community of developers, database administrators, customers, partners, educators, and open source advocates. That community has helped make MySQL one of the world’s most widely used open source databases. As the ecosystem continues to grow and evolve, so do the opportunities for collaboration.  Over the past year, we have […]

MySQL HeatWave Service (MHS) on Oracle Cloud Infrastructure (OCI) already provides multiple ways to create a new DB system, such as restoring from a backup, using Point-in-Time Recovery (PITR), or importing data from Object Storage. However, when creating a new DB system from an existing DB system, especially in another region, the process required several sequential […]

MySQL offers three different approaches to extending the SQL capabilities with the default product you download and install. These are: User Defined Function (UDF) MySQL Manual MySQL Plugin MySQL Manual MySQL Component MySQL Manual For the purposes of this post I will be using the current LTS version MySQL 8.

This lesson should have been learned with the CREATE TABLE of death, but it is worth a refresh.

Do not uselessly grant CREATE and ALTER TABLE

The reason I am posting this reminder is that another crashing bug related to DDL came to my attention.  This bug is only fixed in a recent version of MySQL (probably not affecting 5.6 and 5.7), so if you are running the latest 8.0 or 8.4, you should

You no longer need to manually parse the MySQL Error log via scripting and RegEx pattern matching. Using the component_log_sink_json component you can obtain JSON error logging for easier parsing.

Historically installing MySQL on a RedHat Compatible Linux server was as simple as yum install mysql-server. Today’s MySQL Oracle Linux, Red Hat Enterprise Linux, CentOS, and Fedora 9.7 instructions are not accurate mixing in 8.
