Bit version 1.0.0 marks a major release with significant updates, including a change in the default package registry from "https://node.bit.cloud" to "https://node-registry.bit.cloud", prompting users to update their workspace lock files and .npmrc configurations accordingly. The release also introduces Ripple CI as the default continuous integration tool for building components in the cloud, although local builds are still possible using specific commands. Users who prefer to maintain their previous automation workflows with Bit's tagging commands can continue without alterations, and options are available for those wishing to opt out of cloud builds to ensure all processes remain local.
