PUBLIC COMMENT PERIOD - Simple Binary Encoding (SBE) v2.0 RC1



Version 1.0 of Simple Binary Encoding was the first FIX standard to complete the full cycle of the FIX technical standard process. Due its benefits, SBE v1.0 has gained users both within and beyond the financial industry for low latency applications. Nevertheless, the user community has requested some important enhancements and pointed out some ambiguities or deficiencies in the original standard. Therefore, we are proposing version 2.0. This effort is Release Candidate 1 of that new version.

In Version 2.0, the template extension mechanism was enhanced to allow adding of repeating groups and variable-length data elements to both the root of a message as well as nested within a repeating group without breaking decoders informed by older versions of a message schema. Additionally, control of byte alignment was enhanced to control the alignment of variable-length data elements and repeating groups.
