Non-thermal properties of galaxy clusters have been studied with detailed anddeep radio images in comparison with X-ray data. While much progress has beenmade, most of the studied clusters are at a relatively low redshift (z < 0.3).We here investigate the evolutionary properties of the non-thermal clusteremission using two statistically complete samples at z > 0.3. We obtained shortJVLA observations at L-band of the statistically complete sample of very X-rayluminous clusters from the Massive Cluster Survey (MACS) presented by Ebelinget al. (2010), and redshift range 0.3 - 0.5. We add to this list the completesample of the 12 most distant MACS clusters (z > 0.5) presented in Ebeling etal. (2007). Most clusters show evidence of emission in the radio regime. Wepresent the radio properties of all clusters in our sample and show images ofnewly detected diffuse sources. A radio halo is detected in 19 clusters, andfive clusters contain a relic source. Most of the brightest cluster galaxies(BCG) in relaxed clusters show radio emission with powers typical of FRII radiogalaxies, and some are surrounded by a radio mini-halo. The high frequency ofradio emission from the BCG in relaxed clusters suggests that BCG feedbackmechanisms are in place already at z about 0.6. The properties of radio halosand the small number of detected relics suggest redshift evolution in theproperties of diffuse sources. The radio power (and size) of radio halos couldbe related to the number of past merger events in the history of the system. Inthis scenario, the presence of a giant and high-power radio halo is indicativeof an evolved system with a large number of past major mergers.
