All the 3rd-party modules should be compatible with 7.3, which are already compatible with 7.2. There is no compatibility breaking changes, even templates.

As per announcement we've made earlier - https://www.boonex.com/n/must-read-big-changes-coming-in-september, it will be update every half year, so we'll make more often updates and include less features - all we can make for the available time. Since it looks like we can make 7.3 a bit earlier, then we can spent a but more time for 7.4 and see more include more features into it.
