How to Install / Upgrade: Elastic Stack 9.5.1 released

What happened

Version 9.5.1 of the Elastic Stack was released today. This is the latest version of the stack, and Elastic recommends 9.5.1 over the previous versions 9.5.0. The issues that have been fixed and the full list of changes for each product in this version are in the release notes on the Elastic Blog.

The technical detail

Plan the upgrade around 9.5.1 rather than staying on 9.5.0. Read the release notes for every product you run in the stack before you change anything, then install or upgrade those products to 9.5.1 using your existing Elastic install path. Treat the move as a stack-wide step so you do not leave some products on 9.5.0 while others are already on 9.5.1.

Market and competitive context

Do not treat 9.5.0 as current once 9.5.1 is available. Confirm after the upgrade that every product reports 9.5.1, and use the release notes to check that the fixes you need are present for each product. If a product is still on 9.5.0, finish that upgrade before you call the stack done.
