@ -1,3 +1,14 @@
2020-03-16:
- reworked error handling in std and os libraries: suppressed I/O
exceptions in std FILE functions and return a positive errno value
when it is explicit
- output exception messages to stderr
- added std.loadFile(), std.strerror(), std.FILE.prototype.tello()
- added JS_GetRuntimeOpaque(), JS_SetRuntimeOpaque(), JS_NewUint32()
- updated to Unicode 13.0.0
- misc bug fixes
2020-01-19:
- keep CONFIG_BIGNUM in the makefile
