Campaign Manager up to version 1.4.0 is incompatible with CiviCRM Core 5.67.0 and up.
Starting with CiviCRM Core version 5.67.0, Campaign Manager had an incompatibility due to using code removed in CiviCRM Core 5.67.0. See #114 for more information. This release fixes this incompatibility and is thus compatible with all CiviCRM Core versions.
Note also that the Campaign Dashboard has been converted to a SearchKit display with CiviCRM Core 5.67. This makes Campaign Manager still incompatible. You might want to try https://lab.civicrm.org/extensions/campaignmanager instead.
Changes since Campaign Manager 1.4.0
