Today new version of JSON UDF functions: 0.3.1 was released. This is development release which contains new functionality. You can download
functions from the MySQL Labs website.
Default value for compile option `WITH_PCRE` now is `bundled` independently from the
platform (Bug #71265/18081332 Library name mismatch for PCRE on Ubuntu)
New values, passed to functions `JSON_APPEND`, `JSON_REPLACE`, `JSON_SET` as numbers, empty strings or `NULL`s are converted to JSON objects. Objects, passed as strings are not converted: you are still responsible to put quotes around string values. Also these functions check if element which needs to be inserted is valid JSON value. (Bug #70394/17491708 MySQL JSON UDFs: json_replace can generate invalid target JSON)
README and ChangeLog files use Markdown format (Bug #71261/18023002 REFERENCES IN README MISSING)
`JSON_SEARCH` now accepts third argument: occurrence number, allowing to specify number of occurrence needed. (Bug #70607/17597479 ADD POSSIBILITY TO SEARCH ALL OCCURRENCES WITH JSON_SEARCH)
Added function `JSON_DEPTH` which returns depth of the JSON document.
71510/18154696 `JSON_EXTRACT` returns wrong value if extracts from object which holds two arrays
71530/18160842 `JSON_EXTRACT` RETURNS WRONG RESULT IN VERSION 0.3
71949/18355404 `JSON_VALID` DOES NOT REJECT INVALID DOCUMENTS
70606/17596818 Implement SAFE versions for all JSON functions
And, of course, this release contains all changes made in version 0.2.2
