JDK 21 will be a long-term-support (LTS) release from most vendors, including Oracle. If you’re upgrading from the previous LTS release, JDK 17, then you have many more JEPs to look forward to, summarized here:
We're transitioning to the new MySQL versioning model with our upcoming versions. MySQL database version 8.1.0 will be our first Innovation release, and 8.0.34+ will transition to only bug fixes until 8.0 End-Of-Life (EOL) scheduled for April-2026. Approximately one year from now, MySQL version 8.x will eventually become LTS which will provide ample time for users to migrate from 8.0.x to the 8.x LTS version.
In practice, in this transition period, if you want the latest features, improvements, and all bug fixes for your MySQL databases, use the Innovation release track (eg., 8.1.x, 8.2.x, 8.3.x, etc.). If you need only bug fixes for your MySQL database, use 8.0.x releases (eg., 8.0.35, 8.0.36, 8.0.37, etc.). In both cases, you should plan to update your MySQL databases quarterly accordingly to Oracle Critical Patch Updates (CPU) calendar. When 8.x becomes LTS, you can plan, test, and migrate from the 8.0.x bug fix track to the LTS release track (ex., from 8.0.37 to 8.4.1).
Note that this is an example, there is no commitment that the version numbering will be exactly as presented.
而 LTS 的頻率會是兩年一版，支援 5+3 年，而 8.0 會走四年半：
About every 2 years, a minor version will be designated as Long Term Supported release. This version will have a 5 year premier and 3 year extended support, the same as the previously supported releases. This is similar to MySQL 5.7 and previous releases.
The LTS will also be the last version of the major release. The next (Innovation) release will increase it's major version. For example if MySQL 8.4.0 is the 8.x LTS release, then MySQL 9.0 will be the next Innovation release.
In April 2021, the Supreme Court ruled in a 6–2 decision that Google's use of the Java APIs fell within the four factors of fair use, bypassing the question on the copyrightability of the APIs. The decision reversed the Federal Circuit ruling and remanded the case for further review.
判決全文 PDF 的前面三頁多算是簡介說明這次的重點，Page 44 到 Page 62 則是反對的兩位大法官 (Clarence Thomas 與 Samuel Alito) 所提出的異議，可以看到兩位大法官批評了 copyrightability 與 fair-use analysis 的問題。
The "orafce" project implements of some functions from the Oracle database. The functionality was verified on Oracle 10g, and the module is useful for production work.

We migrated 75 petabytes of internal data stored in nearly 7,500 Oracle databases to multiple AWS database services including Amazon DynamoDB, Amazon Aurora, Amazon Relational Database Service (RDS), and Amazon Redshift.
Cost Reduction – We reduced our database costs by over 60% on top of the heavily discounted rate we negotiated based on our scale. Customers regularly report cost savings of 90% by switching from Oracle to AWS.
More than 100 teams in Amazon’s Consumer business participated in the migration effort.

Features Being Deprecated in Percona Server for MySQL 8.0
TokuDB Storage Engine: TokuDB will be supported throughout the Percona Server for MySQL 8.0 release series, but will not be available in the next major release. Percona encourages TokuDB users to explore the MyRocks Storage Engine which provides similar benefits for the majority of workloads and has better optimized support for modern hardware.
