We fixed a bug so that manually-added dedicated master nodes now persist through configuration changes.
Master nodes are required only for deployments above a certain size, but you could always add them manually. Before this bug fix, if you created a deployment with dedicated master nodes that didn’t require them, making configuration changes later on could result in those master nodes getting dropped.
