GitHubのプライベートリポジトリのReleaseにおいてHomebrewのtapをつかってインストールできるようにしていたところ、以下がエラーが出るようになった。
==> Installing XXXX from xxxx/xxxx
Error: An exception occurred within a child process:
MethodDeprecatedError: Calling GitHubPrivateRepositoryReleaseDownloadStrategy is disabled! Use a vendored GitHubPrivateRepositoryReleaseDownloadStrategy in your own formula or tap (using require_relative) instead.
GitHubPrivateRepositoryReleaseDownloadStrategy
は使えなくなったのでえ、自分のtapで読みこんで使って、と書かれている気がする。

# GitHubPrivateRepositoryDownloadStrategy downloads contents from GitHub
# Private Repository. To use it, add
# `:using => :github_private_repo` to the URL section of
# your formula. This download strategy uses GitHub access tokens (in the
# environment variables `HOMEBREW_GITHUB_API_TOKEN`) to sign the request. This
# strategy is suitable for corporate use just like S3DownloadStrategy, because
# it lets you use a private GitHub repository for internal distribution. It
# works with public one, but in that case simply use CurlDownloadStrategy.
