Core 4.2 to 7.0 11 versions, 4061 sections, compared sentence by sentence. How changes are read

Each version is split into sections and each section into sentences (a table row, a code line and a figure title count as one). A section is followed through renumbering and retitling; a sentence that stayed is matched to its old self, and a changed one is compared word by word.

An edit is editorial when it changes nothing a reader acts on: case, punctuation or quotes; a name written another way (LE Set Scan Enable becoming HCI_LE_Set_Scan_Enable); a renumbered reference; or a sweeping edit, a replacement the version makes everywhere (master becoming central in 5.3), found by counting. Editorial edits are hidden unless you ask for them.

Everything else is a change. A small edit changes at most three sentences of a section that already existed: the kind that is easy to miss. Over several versions the sentences are counted once each, as they differ between the two versions you chose. Changes that add, remove or swap shall, should, may and the like, or a negation, come first, and edits to sentences that stay before sentences added whole; changed values are marked.

Sweeping edits are a judgment by frequency, so each one lists where it applied, and you can count any of them as a change instead.

Versions up to 5.3 are read from the PDF, later ones from the HTML. Where the format changes (5.3 to 5.4) tables and equations come out differently: scraps of tables and equations whose words are on both sides are set aside as extraction differences, but expect more noise in that step.
