As of mid-2015 Hoxy has released version 2.0. This release keeps a the API nearly identical to 1.x, but much of the internals are re-written. Most notably, 2.0 contains:

• HTTPS direct proxying.
• In lieu of calling done(), asynchronous interceptors can return promises or iterators.
• Refactor and simplification of internals, including streams, async logic, and unit tests.
• Various bugfixes and performance improvements.

• 2.2.4 Added babel optional runtime transformer.
• 2.2.3 Fixed broken reference to lodash-node in CLI.
• 2.2.2 Updated hoxy version in CLI.
• 2.2.1 Fixed error in npmignore.
• 2.2.0 Added proxy-level throttling.
• 2.1.1 Ditched babel require hook and instead use compile/prepublish.

• 1.2.4 Improved cheerio markup serialization. Thanks Seth Holladay.
• 1.2.3 Test command now npm test instead of mocha. Proxy close() method now passes args through to server close. Thanks Seth Holladay.
