Discontinuation of the legacy scanning system on May 9th (http://community.eveonline.com/news/news-channels/eve-online-news/discontinuation-of-the-legacy-scanning-system/)
27 April 2017, 5:10 pm
With the release of the new scanning system (https://community.eveonline.com/news/dev-blogs/the-future-of-probe-and-directional-scanning-ui/) earlier in March, the time has come to disable the old scanning system. With the release 119.5 on May 9th (http://updates.eveonline.com/date/2017-05-09/), we will be moving all players to the new scanning system and removing the beta option from the Settings menu.
Additionally, we will be deploying a number of defect fixes in the release and will continue to monitor ways to improve the scanning experience of the new system.
