概述

发布系列是 Cosmos Stack 中一组经过精心整理的组件版本集合，这些版本彼此之间已完成兼容性测试。Cosmos Labs 仅为处于活跃状态的系列提供维护和缺陷修复。 本页是有关发布系列生命周期、当前支持窗口和退役预期的权威信息来源。

​
发布系列包含什么

每个发布系列都包含以下组件的固定版本： 目标是确保某个系列中列出的每个版本都与该系列中的其他所有版本兼容。 随着 Cosmos Labs 逐步整合独立的 Go 模块，SDK 中的某些包可能不会单独列出。

​
当前发布系列

​
升级与支持

发布系列中的受支持版本会随时间更新；在适合采用通用升级方式的情况下，我们会提供升级路径。 新的发布系列会包含相对于前一个系列的破坏性变更。新功能只会考虑回移到最新的发布系列，且仅限非破坏性变更。 Cosmos Labs 同时最多支持两个发布系列。 发布节奏目标是每年推出两个新的发布系列。如果计划中的后继系列延期，最近一个受支持的系列将继续保持活跃，直到其后继系列正式发布。 生命周期策略适用于整个系列，而不是孤立的单个组件版本。某个组件版本只有在出现在活跃的发布系列中时才被视为受支持。 有关安全问题报告和漏洞处理的详细信息，请参阅 Security and Maintenance Policy。

示例

一个示例发布系列可能如下所示：
组件版本
Cosmos SDK0.54.0
CometBFT0.39.0
IBC Gov11.0.0
Solidity IBC Eureka0.1.0
Relayer0.1.0
Attestor0.1.0
以下升级会在不创建新发布系列的情况下更新该系列中的版本：
  • SDK 0.54.0 to 0.54.1
  • Relayer 0.1.0 to 0.1.1
以下升级则需要创建新的发布系列：
  • SDK 0.54.x to 0.55.0
  • CometBFT 0.39.x to 0.40.x
  • Relayer 0.1.x to 1.0.0

​
生命周期终止通知

以下发布线已终止生命周期，不再获得 Cosmos Labs 提供的维护、安全补丁或兼容性支持：
  • CometBFT v0.37.x 及更低版本
  • ibc-go v0.7.x 及更低版本
  • Cosmos SDK v0.50.x 及更低版本
CometBFT v1.x 不受支持。该发布线已被撤回，不属于任何受支持的发布系列。

​
Overview

A release family is a curated set of component versions across the Cosmos Stack that are tested for compatibility with one another. Cosmos Labs provides maintenance and bug fixes only for active families. This page is the canonical source of truth for release family lifecycle, active support windows, and retirement expectations.

​
What a Release Family Contains

Each release family includes pinned versions of the following components: The goal is to guarantee that every version listed in a family is compatible with every other version in that family. Certain packages within the SDK may not be listed as Cosmos Labs consolidates separate Go modules over time.

​
Current Release Families

​
Upgrades and Support

Supported versions within a release family are updated over time, and upgrade paths are provided where generalized upgrades make sense. New release families include breaking changes from the previous family. New features are only considered for backporting to the most recent release family, and only when they are non-breaking. Cosmos Labs supports up to two release families at a time. Release cadence targets two new release families per year. If a planned successor family is delayed, the most recent supported family remains active until its successor is formally released. Lifecycle policy applies to families, not individual component versions in isolation. A component version is supported only when it appears in an active release family. For security reporting and vulnerability handling details, see the Security and Maintenance Policy.

​
Examples

An example release family might look like:
ComponentVersion
Cosmos SDK0.54.0
CometBFT0.39.0
IBC Gov11.0.0
Solidity IBC Eureka0.1.0
Relayer0.1.0
Attestor0.1.0
Upgrades that would update versions within this family without creating a new one:
  • SDK 0.54.0 to 0.54.1
  • Relayer 0.1.0 to 0.1.1
Upgrades that would require a new release family:
  • SDK 0.54.x to 0.55.0
  • CometBFT 0.39.x to 0.40.x
  • Relayer 0.1.x to 1.0.0

​
End of Life Notices

The following releases are end of life and no longer receive maintenance, security patches, or compatibility support from Cosmos Labs:
  • CometBFT v0.37.x and lower
  • ibc-go v0.7.x and lower
  • Cosmos SDK v0.50.x and lower
CometBFT v1.x is not supported. That release line was retracted and is not part of any supported release family.
