v1.2.7

• Fixed a bug where a gc race would cause us to erroneously hold onto a file handle longer than we need to.
• Improved error reporting and logging around sending GET requests.
• Fixed an issue where Transfer-Encoding: chunked didn't work quite correctly, if headers aren't sent in a single read.
• Changed how --ephemeral bottles work; now one running instance if completely independent from another, unlike normal bottles, where multiple executions share the environment.
• Changed how stubs are reported when listing plugins.
• Fixed a bug relating to plugin loading and ARGS clobbering.
• Abstracted out the common.handleize method.
