1.2.0

We have switched to using the ISO 10383 market identifier codes to name calendars, and added several new trading calendars.

Calendars for the following exchanges were added:

• Frankfurt stock exchange (XFRA)
• Swiss stock exchange (XSWX)
• Belgian stock exchange (XBRU)
• French stock exchange (XPAR)
• Netherlands stock exchange (XAMS)
• Portuguese stock exchange (XLIS)
• Tokyo stock exchange (XTKS)

The following calendars were renamed from their traditional abbreviation to their ISO 10383 identifier:

• NYSE -> XNYS
• LSE -> XLON
• TSX -> XTSE
• CME -> CMES
• ICE -> IEPA
• BMF -> BVMF

We have added aliases for the traditional abbreviations for backwards compatibility, so they will continue to resolve.
