2025-06-24	encoding/json/v2: reject unquoted dash as a JSON field name	Joe Tsai
	In this blog: https://blog.trailofbits.com/2025/06/17/unexpected-security-footguns-in-gos-parsers/ the concern was raised that whenever "-" is combined with other options, the "-" is intepreted as as a name, rather than an ignored field, which may go contrary to user expectation. Static analysis demonstrates that there are ~2k instances of `json:"-,omitempty" in the wild, where almost all of them intended for the field to be ignored. To prevent this footgun, reject any tags that has "-," as a prefix and warn the user to choose one of the reasonable alternatives. The documentation of json/v2 already suggests `json:"'-'"` as the recommended way to explicitly specify dash as the name. See Example_fieldNames for example usages of the single-quoted literal. Update the v1 json documentation to suggest the same thing.

2025-04-18	encoding/json: add json/v2 with GOEXPERIMENT=jsonv2 guard	Damien Neil
	This imports the proposed new v2 JSON API implemented in github.com/go-json-experiment/json as of commit d3c622f1b874954c355e60c8e6b6baa5f60d2fed. When GOEXPERIMENT=jsonv2 is set, the encoding/json/v2 and encoding/jsontext packages are visible, the encoding/json package is implemented in terms of encoding/json/v2, and the encoding/json package include various additional APIs. (See #71497 for details.) When GOEXPERIMENT=jsonv2 is not set, the new API is not present and the encoding/json package is unchanged. The experimental API is not bound by the Go compatibility promise and is expected to evolve as updates are made to the json/v2 proposal. The contents of encoding/json/internal/jsontest/testdata are compressed with zstd v1.5.7 with the -19 option.
