Java writes `-1` for "no current snapshot" with V1 and V2 tables and considers
this equivalent to omitted or `null`. This has never been formalized in the
spec, but for compatibility, other implementations can accept `-1` as `null`.
Java will no longer write `-1` and will use `null` for "no current snapshot"
for all tables with a version greater than or equal to V3.
+### Naming for GZIP compressed Metadata JSON files
+
+Some implementations require that GZIP compressed files have the suffix
`.gz.metadata.json` to be read correctly. The Java reference implementation can
additionally read GZIP compressed files with the suffix `metadata.json.gz`.
Review Comment:
@RussellSpitzer what do you think we should do moving forward? Should we
check magic bytes? We could use
`Pattern.compile("\\.gz\\b").matcher(filename).find()`?
