_includes/guide_transactions.md:
* DOS expanded to "denial of service" to improve readability and avoid
conflation with Disk Operating System. Change based on feedback from
@luke-jr. Thanks!
_includes/guide_mining.md:
* Dropped assertion that `getblocktemplate` can't reuse an established
socket. Change based on feedback from @luke-jr. Thanks!
_includes/guide_contracts.md:
* Dropped opening sentences to Contracts section, which were a holdover
from when contracts was a subsection of Transactions. New opening
sentence is now similar to the summary sentences which open all other
sections. Change based on feedback from @mikehearn. Thanks!
* Deleted USA-centric example from second paragraph and merged remaining
parts of the first two paragraphs into a single opening paragraph with
no example. Change based on feedback from @mikehearn. Thanks!
* Removed mention of placeholder byte from multisig example. Change
based on feedback from @mikehearn. Thanks!
Thanks also (in alphabetical order) to @cbeams, @mikehearn, and
@tgeller, among others.
