Some similarities between medieval and Renaissance music would be the type of notation used (the type developed by the end of the medieval period was used in the Renaissance, too.) also the cantus firmus(using a given melody to compose a polyphonic work)was still used but maybe more freely. The forms, fixes such as the rondeaux, viralaie and ballades were still used up to a certain point in the Renaissance. its mostly the change from focussing on the technical side of music in the medieval period to making music for expression and meaning in the renaissance.
Renaissance is a more latin/italian style music, but if you are talking of the era Renaissance, then Renaissance was the era before Baroque, and medevil is from the Medevil ages, which according to Google was from the 5th to 15th century, whereas the Renaissance era was the 13th to 17th era, leading upto the Baroque period of music. I hope this has helped.
The importance of the establishment of major and minor tonality in the Baroque was that each tonality came to be associated with certain types of music. Major tonality was associated with happy occasions and minor tonality with sadness or sensuality.

Renaissance music is defined as that written between 1400 and 1600, although these dates can vary slightly. During this time there was a general awakening across the arts and sciences, and a prolific amount of music was written. The Companion Guide to Medieval and Renaissance Music, written by Tess Knighton and David Fallows, gives useful and comprehensive coverage of the subject, and is an ideal introduction.
There were more established musical instruments by then. There were beginning to be a lot of good performers on those instruments. Composers were broadening their experimentation with music to include two and three part harmonies, instead of just individual polyphonic lines. Those are the three main reasons - there are lots of others. But your question is well put. Renaissance music did indeed sound "fuller" than medieval music.
