Feature #4895
Updated by Junxiao Shi about 5 years ago
Current packet format allows full 64-bit range for TLV-TYPE, but this is causing [implementation difficulty](http://2ality.com/2013/10/safe-integers.html) and bugs such as #4726. The protocol should limit TLV-TYPE to `[1, 2^32-1]` `[0, 2^31-1]` range. This is a trade-off between giving enough numbers for applications and simplifying implementations.
