Python compatibility

• CPython 2.7, 3.3+

• PyPy 2.2+ (possibly 1.9-2.1 as well)

• PyPy3 2.4+

Versioning

This project’s versions follow the following pattern: MAJOR.MINOR.PATCH.

• MAJOR version has been 0 so far

• MINOR version is incremented on backward incompatible changes

• PATCH version is incremented on backward compatible changes

Status

There are some people using this package. I don’t actively use it and as such any help I can offer with regard to any issues is very limited.

0.19.16

• Fix issue preventing TXT record updates from ServiceBrowser

0.19.15

• Track all requested broadcast interfaces in addition to those successfully attached

0.19.14

• Exclude addresses starting with “169.254” from the list returned by get_all_addresses()

0.19.13

• Converts some usage of assert that should likely persist if python -O is used

• Breaks out interface attachment from Zeroconf.__init__ into its own method _add_interfaces

• Adds corresponding behavior for removing interfaces, along the lines of how _add_interfaces functions but in reverse

• Exposes new public method Zeroconf.update_interfaces which triggers add or removal of interfaces

• Prevents stack trace reporting of errors that occur because the network is unreachable, errno.ENETUNREACH

• Updates Zeroconf.send to accept an interface on which filter the interfaces it sends the messages on, such that adding and removing interfaces can attempt to send add/remove messages when the interface is removed

Reduce (and make configurable) the _GLOBAL_DONE threading wait time to improve discovery.

0.19.9

Turn _GLOBAL_DONE into a threading Event to allow for better interruptability at close.
