This pre-release includes the first iteration on CREST support, currently enabled on SISI and expected to be deployed on TQ on Nov 3rd.
Please note that to receive the authentication information back from CCP, pyfa runs a simple server on port 6461. You may have to allow access through firewalls. Environments which restrict which services can be run are not currently supported, but it's on the to-figure-out list.
There are two modes defined in the preferences: implicit (default) and user-defined. For implicit mode, you log into EVE's SSO as a character. The authentication token that is received by pyfa is good for 20 minutes (hopefully CCP will raise this), in which time you are able to browse your fittings, import them, and export new ones to SISI.
For user-defined mode, you must agree to CCP's third-party developer license and apply for your own application through the EVE Developer Portal. Using this mode allows you to store refresh tokens for characters that you authorize pyfa to use, so that you are not faced with having to manually re-authenticate once the access token expires.
These features have not yet been tested on Linux, so feedback from our Linux users would be appreciated (using both wx2.8 and wx3.0).
Please report any issues on our issues page on GitHub; known issues will be consolidated at #383.
