  Minimum OS X version: 10.8

  WARNING WARNING WARNING

  This release of Hammerspoon may break your existing config.

  In particular, please pay attention to the following items:

  • Lua has been updated to 5.3.1, so some core Lua library functions may behave slightly differently, or no longer exist. See the Lua website for the specific changes
  • Many hs.window API methods have changed their return type. They no longer report success/failure, but instead return the window object (allowing the calls to be chained)
  • hs.utf8_53 has been renamed to hs.utf8 and its API changed now that we no longer need to provide backports of Lua 5.3.x UTF8 functions

  If you run into any problems, please reach out to us on GitHub or IRC!

  • We now detect the use of older Mjolnir modules, and display a message suggesting the user update their config, iff they have had a crash
  • The text input field in the Console window will now grow/shrink vertically (use Option-Enter to add a line without submitting the Lua code, and Option-Arrows to navigate)

  GitHub release page

  Minimum OS X version: 10.8

  Note

  Core

  • Changed: Lua callbacks from C/ObjC extensions should now be unable to corrupt the Lua function registry if they are overfreed (which is a known bug in hs.notify)

• 0.9.26 - 14 Mar 2015

  GitHub release page

  Minimum OS X version: 10.8

  Note

  • There are two API changes in this release, both in hs.eventtap. See the Extensions section below for more information

  Core

  • Added: Preferences window now includes an option to disable sending crash reports, and a link to our privacy policy for crash reports. We would humbly request that you not disable the crash reports, as they are super helpful to us in improving Hammerspoon.

  Core

  Extensions

  Important note

  GitHub release page

  Minimum OS X version: 10.8

  WARNING WARNING WARNING

  This release of Hammerspoon will break your existing ~/.hammerspoon/init.lua file. All of the extensions are now using camelCase for their APIs, instead of the previous underscore separated names.

  Please review the API documentation at http://www.hammerspoon.org/docs/ and update your init.lua. You will find that no APIs have changed their behaviour, and porting your configuration file is usually just a case of changing some_function_name() to someFunctionName().

  This will be the first and only dramatic overhaul of the API before 1.0 is released. We are using the Semantic Versioning guidelines, so post-1.0 there will be no API-breaking changes without the major version number changing.

  We thought long and hard about this change and felt that a few minutes of disruption to the small number of users at this stage, would be worth it to have cleaner APIs for all users in the future. We’re sorry that this causes some extra work for you, but we hope you too will prefer the new style!

  Core

  • Changed: Extensions can now be loaded from ~/.hammerspoon/ as well as the previous locations. All require() paths are now printed to the console at startup.

  Extensions

  • Changed: All extensions are now using camelCase for their APIs, which will break all existing user configs (sorry!)
  • Changed: hs.ipc no longer explodes if another instance of Hammerspoon is running. It will still fail to initialise, but it won’t bring down the whole app.
  • Changed: hs.milight now has two constants that specify the minimum and maximum brightness levels
