Functions depricted in package

[samanway1996]

We were using shinydashboardPlus package for developing shiny dashboards, which we would deploy in Rstudio connect. But as some functions have been depricated in new version, hence Rstudio connect, which has the latest version of package installed, started throwing error, while deploying dashboards developed with these functions.
Error:
could not find function "dashboardHeaderPlus"

Please add backward compatibility to these functions. Thanks.
