About grpc java version support ?

[shalk]

I found gRPC java minor release really monthly. But We can not upgrade the version too often.

Is any release policy or version support We can follow ? like https://protobuf.dev/support/version-support/#java

What in particular do you like about that protobuf link? It just shows how they support older major versions for longer when they make a new major version. When a new minor version is released, it marks the end of support for the previous release. gRPC Java has no planned new major version.

Releases are every six weeks. The two most recent releases are supported. Historically, for severe security issues we have fixed even older releases when easily able, but in general we optimize to make upgrading easy (e.g., by not making new major versions) instead of supporting very old versions.

Thank you for your reply ! The FAQ is very useful !

In our case, the link show Public Support Until, So we will upgrade the version before that time. And We will align to the lts version.

I think i will upgrade gRPC version every 3 month with two most recent releases.

For protobuf, the old major version isn't an LTS of sorts. Yes, it has extended support, but that's to give the ecosystem time to get off of the version. If that extended support is encouraging you to stay on the version, that is the opposite of the intention. And it will cause some problems, as the ecosystem as a whole has to regenerate code with the newer version of protoc, as 5.x won't support 3.x generated code so the ecosystem can't start using a 5.x until it is off 3.x.
