scatrin commented on issue #329: Improved conversions handling + pluggable
conversions support [AVRO-1891, AVRO-2065]
URL: https://github.com/apache/avro/pull/329#issuecomment-426912754
Glad you like it @kgalieva and @ivangreene. I'll hopefully have time to
rebase it during today. Is there something else I need to do for it to proceed
to code review?
