## 3.15.3
### Fixes
* The JSON reporter's number handling is locale-independent. (#3176)
* Removed leftover debug message from `catch_discover_tests` (#3177)
* Fixed typo in the "Could not jump to the Nth element" exception message (#3181)
### Improvements
* `catch_discover_tests` registers tests in deterministic (alphabetical) order.
* `catch_discover_tests` has been rewritten to be massively faster.
* Preparing the actual CTest script is significantly faster.
* Parsing the JSON test array is significantly faster.
* Running without `ADD_TAGS_AS_LABELS` set is 10-15% faster (as opposed to being the same speed) (#3169)
* The new implementation is about 4x-5x faster, so registering 500 tests now takes ~350ms (down from 1.1s).
* JSON writing is faster
* Small improvement in writing non-string values
* ~6-40% improvement in writing string values that do not need escaping
* ~1-6% improvement in writing string values that do need escaping
* Better support for infs and NaNs in JSON output
