the 5.7.0 release.

+=head2 Unimplemented (But Recognised) POSIX Regex Features Now Fatal
The unimplemented POSIX regex features [[.cc.]] and [[=c=]] are still
-recognized but now cause fatal errors. The previous behaviour of
+recognised but now cause fatal errors. The previous behaviour of
ignoring them by default and warning if requested was unacceptable
since it, in a way, falsely promised that the features could be used.

variable interpolation.

In some platforms Perl can be configured to use 64-bit integers,

+=item In string, @%s now must be written as \@%s

+(F) It used to be that Perl would try to guess whether you wanted an
+array interpolated or a literal @. It did this when the string was
+first used at runtime. Now strings are parsed at compile time, and
+ambiguous instances of @ must be disambiguated, either by prepending a
+backslash to indicate a literal, or by declaring (or using) the array
+within the program before the string (lexically). (I<Someday it will
+simply assume that an unbackslashed @ interpolates an array.>)
