* February 9
G198	added "no points" option in proof mode
I199	when debugging METAFONT it will show the pen memory allocation status

* February 19
B200	incorrect rounding when plotting one point with lpen or rpen

* March 1
B201	Alphatype broken characters should be at multiples of 10 and y not so low

* March 31
I202	sqrt of negative should get MF error message not a SAIL one
T203	definition of pmin said -xrastmin not -xrastmax
T204→195	≥ instead of > in "too tall" error

* July 8
I205	crsmode tries to choose as small a number of offsets as possible

* July 24
G206	added temporary binput to allow input of Tung's Chinese characters in binary

* November 28
R207	need to check that pen size ≥1 in ddraw
G208	added provision to flag characters that should be set left-to-right on CRS

* December 2
G209	major extensions by Lyle Ramshaw for Xerox-oriented fonts, also tfx→tfm.

* December 13
I210→209 title parameters are changed to upper case
I211	Alphatype routines changed to load module instead of source file

* December 19
B212	used the variable k before it was defined in hrastplot!

* February 12, 1981
S213	constant .999 changed to .99999 in ccubics

* April 10
L214	problem in "useto" and "wordout" in the I/O routines causes clobberage

* May 17
G215	extensions to Alphatype output (break both x and y, new ANT format)

* May 23
S216	certain cases of Alphatype encoding did not quite close the cycle

* August 4
S217	after "x" to exit an error, another error could occur in tfmmode
I218	error conventions made compatible with TEX, without control characters
I219	nonstop mode added for batch processing

* August 7
I220	if pmem nearly full, it is automatically cleared out to avoid overflow
