In late 2020, Apple announced their intent to  add a new feature to their Intelligent Tracking Prevention implementation  in Safari  called  CNAME Cloaking Defense , to be rolled out with the release of Safari and IOS 14 .   Like  many of the other efforts in Apple’s Intelligent Tracking Prevention schemes, t his feature is designed to  limit  the lifespan of cookies set by hosts which have a CNAME  pointing to a domain name which does not match the visited page’s domain name  to seven days .    Since Munchkin JS  uses  cookies  set by  a CNAME, and the underlying host to which the CNAME  ({your instance }.mktoweb.com )  points   will never match the  domain name of a visited  page ,  cookies set by Munchkin in Safari 14  browsers  will be capped to a  seven-day  lifespan.    While the reduction in cookie lifespan will have some effect on tracking known leads , traffic from Safari generally  represents  less than 10% of requests handled by Munchkin.        T he re are no apparent easy solutions to this  issue,  and each would require  significant intervention  both  on the part of  Adobe engineering and  subscribers .    Adobe will continue to explore long-term options for improving consistency and accuracy of web tracking behaviors, but at this time we have decided not to t ake any extraordinary measures to try to circumvent this change and restore  long lifespans for Munchkin cookies.  Instead,  we have decided to  focus  on  our efforts  to  integrate  Marketo  web tracking with the  Adobe Web SDK   so that all Adobe  Marketo  En gage  customers  can benefit from our best-in-class web tracking solution.   We will have more information to share when we are closer to release of this solution.   ...

Deprecation of Email V1 began  almost  two years ago  and beginning with the  March  maintenance   release to London & Netherlands subscriptions on  March 17 th , 2021  and all other subscriptions on March 19 th , 2021 , all API support for V1  e mails will b e ended.  A fter this release,  any attempts to interact with V1 emails via the Asset APIs will result in errors and no actions taken .  All known remaining users since  February 24 th , 2021  have been notified ,  but  it is possible  that there are still integrations which may attempt to interact with these assets.  The most common types of affected integrations are services  which  offer digital  asset management, translation, and localization .     If you do observe integration failures as a result of this change,  you will still be able to upgrade problematic assets  by editing and approving them .  Once an email asset is upgraded to V2, you should be able to resume using it with integrated services.   ...

  Beginning on  2020-05-07 ,  Marketo  will start to roll out version 159 of the Munchkin  JavaScript  Client.   Subscriptions which have the  Munchkin Beta f lag enabled  will see changes from this release first, after which deployment will begin on a rolling basis to subscriptions which  do not have this flag enabled.    The  most significant change in this re lease is the  deprecation of Munchkin Associate Lead.       Changes     Deprecation of Associate Lead       Beginning with this release, when the  Associate Lead method  is invoked, a warning will be issued to the browser console, indicating that the method will be removed in a future release.  For more details on what to expect from this deprecation  process   read this announcement .     Reversion of Domain Selector V2       Despite best efforts to offer an improved the selection of the domain for the munchkin cookie, the change proved disruptive in certain cases.  We will be reverting the mainlining of this change, and the f unctionality will be  hidden behind a configuration flag  as it was prior to version 158 .     Fixing Undefined Referrer when Calling Visits Web Page       Previously when calling the  Munchkin API to submit a Visits Web Page event , the referrer would be submitted with a value of ‘undefined’.  With version 159, the referrer will now be cor rectly recorded.  This bug did not  affect  normal web visit tracking.       Rollout     As with all Munchkin releases, this version will be a phased rollout,  initiallity  to customers who have enabled  Munchkin Beta  for their subscriptions, and later for all  Marketo  subscriptions.  Th is schedule is subject to change.   Customers who need early access to these features in their subscriptions should consider enabling Munchkin Beta.   Date   Release Type   Percentage   2020-05-07   Beta   10%   2020-05- 21   Beta   50%   2020-0 6-05   Beta   100%   2020-06-19   General Availability   10%   2020-07-10   General Availability   50%   2020-08-04   General Availability   100%     ...
