Today, Canonical announced the general availability of Legacy Support, an Ubuntu Pro add-on that expands security and support coverage for Ubuntu LTS releases to 12 years. The add-on will be available for Ubuntu 14.04 LTS onwards.
Kubernetes follows an N-2 support policy (meaning that the 3 most recent minor versions receive security and bug fixes) along with a 15-week release cycle. This results in a release being supported for 14 months (12 months of support and 2 months of upgrade period).
Today, we’re announcing the preview of Amazon Elastic Kubernetes Service (EKS) extended support for Kubernetes versions. You can now run Amazon EKS clusters on a Kubernetes version for up to 26 months from the time the version is generally available on Amazon EKS. Extended Support is available as a free preview for all Amazon EKS customers, starting today with Kubernetes version 1.23.
Here's one major change coming down the road: Long-term support (LTS) for Linux kernels is being reduced from six to two years.
主要的原因是舊版用的人並不多:
Why? Simple, Corbet explained: "There's really no point to maintaining it for that long because people are not using them." I agree. While I'm sure someone out there is still running 4.14 in a production Linux system, there can't be many of them.
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.
