The JSON output now uses the Proto3 "JSON Mapping", which is slightly incompatible with the existing JSON format. Mainly, 64-bit numbers are represented as strings, and addresses are decimal strings instead of hex. However, the older JSON format is still accepted by "report changes" to ease migration.	2024-08-16 00:52:24 -06:00
