[manila] RC1 is available, No IRC meeting on 1st April 2021

Hello Zorillas, RC1 builds have now shipped for both manila and manila-ui, thank you all for your hard work on getting these out on time. It's now time to test these builds and learn of any release blocking bugs and fix them. Some down time is also in order between now and the PTG! In order to let folks to plan for that, I'd like to skip the IRC meeting on 1st April. In the meantime, please feel free to post your issues to #openstack-manila and to this email list. Thanks, Goutham
