No. While you are free to migrate to the NEW NamasteLight version if you wish, the CLASSIC version will continue to be supported and work as it always has.
However, as of December 16, 2019 - the NamasteLight CLASSIC version will no longer have MINDBODY integration capabilities.
If you are a MINDBODY client, you will want to switch to the NEW NamasteLight version prior to the date listed above.
Please contact firstname.lastname@example.org if you have any questions.
