	## Supported Cosmos SDK versions
	| CosmJS version | Supported Cosmos SDK version(s) |
	| ------------------------------- | ------------------------------- |
	| ^0.29.0 | 0.44.x, 0.45.x, 0.46.x |

This is what shows up on the NPM website and in the official documentation when a release is tagged and published, and it's fairly useless - it implies CosmJS still lacks support for Cosmos SDK 0.47.

The 15 different packages' readmes need less outdated info, and maybe more package-specific badges like the ones displayed for these packages:

https://www.npmjs.com/package/nuxt
