Hopper’s auto-updater surfaces these notes in-app under Settings → Updates and in the title-bar pill when a new version is available. The full archive lives here.

​
1.2.0 — May 20, 2026

Multi-hop agent navigation. Asking the agent to log on, browse a dataset, switch to CICS, or log off now runs as a single navigate_to call that plans the route, validates each step, and recovers from unfamiliar screens on its own.

​
Agent navigation

  • Single navigate_to call replaces 3–6 manual tool calls per layer change.
  • Plan-mode UI on every navigation card — see the planned hops and which one is running.
  • Recovers to login, ISPF, SDSF, or CICS from any starting state, including unrecognised screens.
  • CICS sign-in, CICS sign-off, and TSO/E re-login each compose end-to-end in one call.

​
Tool-card icons

  • Read-only tools, key-press primitives, field writes, and navigation each get their own glyph in the chat panel. You can see at a glance whether a tool call had side effects.

​
1.1.6 — May 15, 2026

​
Bug fixes and improvements

  • Fixed a misleading “Not Found” error under Host when the installed app’s chat-history database had been touched by a newer dev build.

​
1.1.5 — May 12, 2026

​
Bug fixes and improvements

  • Added a Request credentials link in the Connect to Mainframe form, Edit Connection modal, and Settings → FTP so trial users can request mainframe access without leaving the app.

​
1.1.4 — May 11, 2026

​
Bug fixes and improvements

  • Fixed the ”···” actions menu in Settings → API keys hiding behind the table.
  • Removed the duplicate Check for updates row from Settings → Updates.

​
1.1.3 — May 11, 2026

​
Bug fixes and improvements

  • Fixed a data-loss bug where ISPF Edit + SAVE wiped untouched characters on the edited row.
  • Restored live token-streaming and auto-scroll in the chat panel.
  • Investigating a failed job now uses one direct FTP fetch instead of driving SDSF — faster and immune to screen-settle timeouts.
  • First-login ISPF “Licensed Materials” banner clears automatically.
  • More reliable ISPF / SDSF navigation on TLS-wrapped TN3270 sessions.
  • The Planning next moves… loader hides as soon as the assistant starts writing.

​
Diagnostics

  • TN3270 wire-trace can be enabled with HOPPER_TN3270_TRACE=HOST (or ALL); output lands in dev-logs/tnz.log.

​
1.1.2 — May 7, 2026

​
Bug fixes and improvements

  • Quitting Hopper is ~5 seconds faster.
  • Fixed title-bar icon alignment on macOS.

​
1.1.1 — May 7, 2026

​
Bug fixes and improvements

  • Removed the stale v1.0.0 pill from the nav header. The current version stays visible in Help → About.

​
1.1.0 — May 7, 2026

In-app auto-update. A pill in the title bar surfaces new releases, walks you through the download, and offers a Restart to apply. No more native dialog boxes.

​
Auto-update

  • Update pill in the title bar (macOS) or top-right corner (Windows / Linux), with a popover for version diff and release notes.
  • Settings → Updates section with current version, last-checked time, and an Update mode preference (Automatic / On startup only / Manual / Off).
  • Session toast when an update is detected, suppressed for the first 5 days after a fresh install.

​
Settings

  • Cmd+, (macOS) / File → Preferences… now opens the unified Settings surface instead of a raw-YAML editor. API keys, mainframe / FTP connection, privacy, and updates all live in one place.
  • Update errors surface in Settings instead of as native dialogs.

​
Stability

  • Single-instance lock — opening Hopper from the Dock or Spotlight focuses the existing window instead of spawning a duplicate.
  • The Python sidecar is drained explicitly on quit and on Restart-to-update.
