This is an intentional change that removes an ambiguity.
Each measurement name can be used in other .meas expressions. Suppose you have two measurement names "A" and "A+A". What would be the meaning of the expression "A+A"?
In short, math operators are not allowed in parameter names.

A new error seems to have crept into .MEAS directives on the 24.1 branch.
Measurement names are apparently not now allowed to have a sign character in them, e.g.:
.MEAS Tpd+ param T1-T0
.MEAS Tpd- param T11-T10.. results in:
I:\tony\Documents\Simulations\LTspice\Comparator\UniversalComp\Dev\UniversalComp_Test.net(37): syntax error
.MEAS Tpd+ param T1-T0
???????? ^^^^^^^^^^^^^
I:\tony\Documents\Simulations\LTspice\Comparator\UniversalComp\Dev\UniversalComp_Test.net(38): syntax error
.MEAS Tpd- param T11-T10
???????? ^^^^^^^^^^^^^^^
This has worked in all previous versions. In the logfile, normally it would show, e.g.:
tpd+: t1-t0=1.08114e-08
tpd-: t11-t10=1.09962e-08
