@thymikee thanks for sending this over 👍

Just cross checking, we want this included inside 0.69? I'm a bit concerned about shipping a stable version of RN with the CLI on -alpha. Are we planning to land CLI 8 stable before RN 0.69 stable hits NPM?

@cortinico yep, we'd like it to land in v0.69. There are no functional changes planned for v8, maybe some warning messages or such for deprecations. We plan to promote it to stable before 0.69 hits its final RC
