As the title implies, my .plan file has broken the one megabyte barrier at long last:
{12:10:40 @ Thu Jan 06}[drwho @ windbringer ~]() $ ls -alF .plan
.rw-r--r-- drwho drwho 1.0 MB Thu Jan 612:03:39 2022 .plan
{12:10:43 @ Thu Jan 06}[drwho @ windbringer ~]() $ du -sh .plan
1.1M .plan
I've also updated it, the first for this year. All the usual warnings apply.
