CHANGELOG: 1.17.10 mentions new 'aws ecr get-login-password'

[pda]

The v2.0.0 changelog entry includes:

Removed support for the ecr get-login command in favor of ecr get-login-password

... however the new get-login-password isn't mentioned anywhere in CHANGELOG.rst.

The get-login-password command was introduced in #4874 in commit 00cfc2c which merged in d1f7339 and was first tagged in 1.17.10:

$ git tag --contains 00cfc2cb | sort --version-sort | head -n1
1.17.10

This pull request updates the 1.17.10 changelog entry to mention this added get-login-password command.

This is important because awscli v2 completely drops the previous get-login command, and many downstream consumers/maintainers will be trying to understand the window of cross-compatibility where awscli supported both commands.

(Unfortunately, get-login-password only landed in 1.17.0 on 2020-02-05, and get-login was dropped as of v2.0.0 on 2020-02-11, so there's only six version-days of cross-compatibility. I understand the v2 release represents breaking changes and v1 is still being maintained for now, but it still puts dependent tooling like https://github.com/buildkite-plugins/ecr-buildkite-plugin in an awkward position of trying to detect and support both.)

Related context:

• get-login-password proposed in Proposal: aws ecr get-login-password #4867
• get-login-password implemented in adds aws ecr get-login-password customization #4874
• get-login removed in [v2] Remove ecr get-login command #4886
• Example of a dependent project version-pinning to v1 due to this change: windows: pin awscli to v1; v2 breaks 'aws ecr get-login' buildkite/elastic-ci-stack-for-aws#670

Thanks for the pull request. I added an additional commit on top so that we include it in our JSON file for that version. This is important because we regenerate the CHANGELOG from these files so it would have been wiped away on the next regeneration. Thanks again!
