libfawk 1.2.0 (r895)
~~~~~~~~~~~~~~~~~~~~
	[doc]
		-Fix: typo: example for <= and >= had the wrong operator
		-Fix: missing </i>
		-Add: text block does not accept empty expression
		-Add: document the no-array-in-array limitation of []

	[fawk]
		-Fix: expect stack to be empty only if there was no runtime error; indicate runtime error

	[libfawk]
		-Change: API CHANGE: fawk_error() gets location information in separate arguments so the error print function does not have to figure it from the context
		-Optimize: remove code duplications to reduce code size
		-Fix: compiling instruction .line field from the wrong context field
		-Fix: libfawk_error() needs to get line number of column number location info as long (because int may be as small as 16 bits)
		-Fix: ABORT uses libfawk_error for announcing the message instead of fprintf to stderr
		-Fix: uninitialized var on array index conversion
		-Fix: low level numeric conversion in the parser doesn't depend on double but uses fawk_num_t since strtod is also virtualized
		-Fix: textblock expression may contain spaces before the escape-back-to-text character
		-Fix: ungetch returning to previous line restores previous max col value too instead of reporting 1000
		-Fix: for(in) shouldn't crash for non-existing arrays (e.g. A.X where A[] is empty)
		-Fix: create local var array on first symref
		-Fix: textblk accepts [] in expression
		-Fix: don't abort after failed to-string cast
		-Fix: do not assert but return runtime error for FOO[1][]
		-Fix: accept STRNUM for STR for succesful cast in concat
		-Fix: typo in cast-to-str: fallback result should be NIL or STR
		-Cleanup: namespace pollution: CURR_IP and PUSH_IP are now FAWK_ prefixed
		-Add: centralzie fawk_assert(), stop using assert() directly
		-Add: virtualize strtod() to fawk_strtod() so caller has a chance to replace the numeric type without having to convert doubles
		-Add: virtualize fmod() into fawk_fmod() so execute.c doesn't depend on math.h
		-Add: do not hardwire %f and %g in numeric printf, because the numeric type is user defined; use a printf format string define in the config

	[sc]
		-Add: make fawk_assert() redefinable
		-Add: make math.h optional
