I have noticed that sometimes Flagrow.io takes a lot of time before updating the version shown. However this should have no impact to the ability of people to install the latest version.
All Bazaar does in is running composer require, so it will use whatever latest version is available from Packagist.
The only thing that might not work while it's outdated are the "new update" badges in Bazaar. But it'll show up once Flagrow.io eventually updates.
