What version is recommended for a newly launched TiDB cluster in a production environment?
Are there comparison documents and new feature documents for each version?
It should be convenient for horizontal comparison.

TiDB v7.5.0 LTS or other LTS versions

I am using V7.5.1 and it feels pretty good. For a comparison of new features, you can refer to the following article:

TiDB 8.1.0 is a Long-Term Support Release (LTS).
Some vendors support direct upgrade :smiley:

TiDB 8.1.0

Version 7.5.2 was released yesterday, I recommend using v7.5.2 directly.
The community has been active recently, so there is also support.

I suggest directly using TiDB 8.1.0 LTS. Since it’s a long-term support version, there’s no need to worry.

It is now 8.1.0

I recommend using the new LTS.

There are no issues with the LTS versions, but you can pay attention to the release notes for some feature changes. For example, after one upgrade, the memory control parameters of TiDB were adjusted from session level to SQL level, which affected the business. However, since you are making a new choice and not upgrading, it doesn’t matter.

Indeed, upgrading the old version requires testing the business again; when adding a new database, the database is also tested during business testing and stress testing.

We have already standardized to V7.5.1 LTS.

Version 7.5.2 has fixed so many bugs. It’s much better to use this one directly.

| username: 扬仔_tidb | Original post link

We are still on v5, and the business has been stable without upgrading. I see that everyone else is on much higher versions. Should we also upgrade, otherwise we will be too far behind?

: yum: Stability overrides everything, upgrade only when necessary.

| username: zhanggame1 | Original post link

We have used 7.5.2 in production and will deploy it next week.

| username: Kongdom | Original post link

:muscle: Enterprise edition users can upgrade freely, with original factory experts providing support.

Database vendors provide assurance, but the business needs to ensure it themselves.

LTS吧

7.5 is quite stable.
