docs: recover the A/B/C/D image-fetch design rationale (blocking curl chosen over async/in-process/disk-cache), note the curl prerequisite, and document caching's per-render-pass scope check-in: da46e58bd7 user: wdc tags: html
19:56
docs: record per-sender image allow-list + beacon-blocking design, the messages.c/text822 cross-.do crash writeup, and HTML/MIME rendering + new options in mail-quickstart check-in: ed341a16a6 user: wdc tags: html
19:42
messages: per-sender image allow-list (ams.imageallowlist pref + This Message menu item), deliberately independent of tracking-pixel blocking; fix cross-.do crash via amsutil relay (avoid raw externs/suppressed text822 routines); terser options help text check-in: 91b95110bf user: wdc tags: html
15:38
messages: block obvious tracking-pixel images pre-fetch (ams.blockbeaconimages pref, on by default); render nothing rather than placeholder text to avoid blowing out lset table column widths check-in: 1ad1ae2e4f user: wdc tags: html

htmlatk.c: sniff real image format when declared Content-Type's decoder fails; suppress routine gif__Load stderr on the speculative first attempt; htmlatktest.c: fix binary-corrupting UTF-8 conversion in cid: test resolver check-in: 15c117b15d user: wdc tags: html
04:06
messages: fetch remote <img> content via curl (httpimg.c), gated by ams.loadremoteimages pref + per-message override, im.c SIGCHLD race fix, per-render-pass fetch cache check-in: 007ce9ec43 user: wdc tags: html
