• Issue #23 fixed by @rsnickell

Issue with results folder names

• Fixes #21 (reported by @lucalanca)

Update grunt-phantomas

Update grunt-phantomas from v0.8.0 to v0.10.0.

Fix bug with onDOMReadyTime & windowOnLoadTime

Renamed onDOMReady --> domInteractive and windowOnLoadTime --> domComplete, just like phantomas.
This was causing a bug "Cannot read property 'average' of undefined".

Updating grunt-phantomas

• Updated to grunt-phantomas 0.8.0
  • phantomas is updated to v1.4
  • new metrics availabled in the full grunt-phantomas report:
    • assetsWithCookies
    • DOMmutationsInserts
    • DOMmutationsRemoves
    • DOMmutationsAttributes
    • videoCount
    • videoSize
• The limits are sent to grunt-phantomas, that displays failed assertions in red in the full grunt-phantomas report.
• The warnings are now triggered on the median value, instead of the average value, similarly to grunt-phantomas.

Passing advanced options to Phantomas

• #16 Added phantomasOptions (read this chapter in README file).

Small improvements

• Fixed #11 : Link to the full grunt-phantomas report not working. Warning: i made some changes to the names of each url's result folder when the url was containing "&", "%" or "=". This can break your history, unless you copy the JSONs from your old folder into the new one.
• Increased the default limit for whiteSpacesSize in HTML from 5000 to 8000, because obviously nobody minifies HTML
• Added a new multipleRequests warning: Some static assets are requested multiple times
