# Release notes

> What changed in each Hopper release. Most recent first.

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.
