Version 3.6.0 of the developer tools for the Slack platform is joining the summer fun!

    We added a new runtime_not_found error code that will appear when a hook script cannot be found because the runtime for a project wasn't found during execution.
    We updated the slack install command to create and install new Bolt Framework apps that are configured to use app settings as the source of truth (i.e., remote manifest).
    We added a download link to the latest version of the Slack CLI for Windows. Manual installations for the latest are now also supported at the following links:
    https://downloads.slack-edge.com/slack-cli/slack_cli_latest_linux_64-bit.tar.gz
    https://downloads.slack-edge.com/slack-cli/slack_cli_latest_macOS_arm64.tar.gz
    https://downloads.slack-edge.com/slack-cli/slack_cli_latest_macOS_amd64.tar.gz
    https://downloads.slack-edge.com/slack-cli/slack_cli_latest_macOS_64-bit.tar.gz
    https://downloads.slack-edge.com/slack-cli/slack_cli_latest_windows_64-bit.zip
    We fixed a bug: we now allow new projects to be created more quickly by using a HTTP HEAD request to check whether the template URL exists.
    We fixed a bug: we now order the outputs of authentication details from the slack doctor command according to an alphabetized list of team domains.

Version 3.5.2 of the developer tools for the Slack platform has landed!

    Beginning September 1, 2025, the Slack CLI installation script will no longer include deno as part of the installation. We recommend installing deno separately and configuring CI systems as needed for app development (such as for ROSI apps).
    The sdk_hook_not_found error now provides a link to the Deno starter template hooks.json file as a working example.

We're making some changes to the entry requirements for apps submitting to the Slack Marketplace. Currently, we require that apps submitting to the Slack Marketplace have at least 10 installations on active workspaces. The goal behind this requirement is to ensure that all apps are thoroughly tested on a workspace other than the one they were built on. However, starting August 11th we will be reducing this requirement from 10 to 5 active workspaces! As part of this change, after this date we will automatically block submissions that don't meet this requirement. Please note: this requirement will not apply to apps that are already approved for the Slack Marketplace or submissions from apps that are not yet approved but are in the review process.
