3. Consider What Versions of the LDP Components to install
· See the Library Data Platform section of the FOLIO documentation, which includes a recommendation matrix for the 3 components by FOLIO release
· In general, install the latest production release for each component of the LDP software. The LDP and ldpmarc software components do not have a dependency on FOLIO (flower release) software versions, but the folio-analytics software component is intended to be used with specific FOLIO releases - https://github.com/folio-org/folio-analytics#releases
· It is safer to install only releases (tags) and to read the release notes and make adjustments to your environment if necessary
· Do not install beta versions in production environments, as they need to be tested before they are used in production
