This corrects a small bug in zic that caused it to output an incorrect year-2440 transition in the Africa/Casablanca zone. More interestingly, zic has grown a "-r" option that limits the range of zone transitions that it will put into the output files. That might be useful to people who don't like the weird GMT offsets that tzdb likes to use for very old dates. It appears that for dates before the cutoff time specified with -r, zic will use the zone's standard-time offset as of the cutoff time. So for example one might do make install ZIC_OPTIONS='-r @-1893456000' to cause all dates before 1910-01-01 to be treated as though 1910 standard time prevailed indefinitely far back. (Don't blame me for the unfriendly way of specifying the cutoff time --- it's seconds since or before the Unix epoch. You can use extract(epoch ...) to calculate it.) As usual, back-patch to all supported branches.
