  • profile pages on the account domain, and links verified by rel="me"
  • Japanese cut into words and looked up on the device
  • questions on published studysets, answered by learners
  • a show's tags follow it whatever it is called
  • a round in the order cards come, shared daily limits, and a start screen
  • an empty library says it is on its way during the first sync
  • your own studyset is yours, not one to add
  • the first start offers instances as tiles
  • an instance says where it keeps people's data
  • data locations as precise as a country or a state
  • the server on halkyon_base
  • the app on halkyon_app, with its own icon
  • one account across an instance's services (ADR 0016)
  • SRP-6a, the register's half and the device's
  • TOTP and recovery codes
  • halkyon_keys, an account's keys on the device
  • recovery codes kept under the instance's key
  • passwords taken as RFC 8265's OpaqueString
  • a password with TOTP on the register, and resets
  • say when an account signs in with its password
  • Learn's and Todo's servers take password sign-in

  Fixes

  • read a large release without waiting on git for ever
  • copies keep their ties to PDF pages, and ids swap whole
  • words held in topics, a chosen destination, faster adds
  • releases in parts, and say what kept a copy from being made
  • counts worked out once and kept until something changes
  • what everyone follows is read once, and two server hot spots
  • a path's steps, untagging and the card browser in bulk; fix untagging
  • a search finds keys by their first characters, indexed
  • the fork's signed commit with inbound merges and fast deletes
  • the fork's signed commit with fast merges, and #150 fixed
  • the checks run as a hook from a worktree too
  • the checks fetch the packages first
  • the fork's signed commit with fast merged deletes and batched inserts
  • the check limited to changes sees uncommitted ones too
  • count per-network limits by the visitor behind Caddy
  • adding an authenticator takes a code from one confirmed before
  • a password set up for good stays, through resets too
