W3C finally signed off on SOAP 1.2 by releasing it as a Recommendation.  SOAP 1.2 is a small constellation of four documents:

• SOAP Version 1.2 Primer
• SOAP Version 1.2 Messaging Framework
• SOAP Version 1.2 Adjuncts
• SOAP Version 1.2 Assertions and Test Collection.

Changes from SOAP 1.1 are summarized in From SOAP 1.l to 1.2 in 9 points [warning: it's reads like a sales brochure].  While I am not entirely happy with its content, I am happy to see it finally arrive.
