+# winTerm 1.3.0-alpha3
+
+**This is an alpha prerelease for local testing. It is not a stable release.**
+The current stable release remains
+[v1.2.0](https://github.com/HelloThisWorld/winTerm/releases/tag/v1.2.0), and
+`/releases/latest` continues to point there. This alpha is published only as a
+tagged GitHub prerelease; it is not listed on the winTerm website and is not
+submitted to WinGet.
+
+winTerm 1.3.0-alpha3 fixes the five issues reported from local testing of
+[1.3.0-alpha2](https://github.com/HelloThisWorld/winTerm/releases/tag/v1.3.0-alpha2).
+The Command Timeline feature set is otherwise unchanged.
+
+## Changes since alpha2
+
+- **No more stray `\` characters before the prompt.** The shell integration
+  module terminated every escape sequence with two characters instead of one,
+  so the terminal printed a leftover backslash per emitted mark — three before
+  the first prompt and four after each command.
+- **The Timeline records exactly the typed command.** The prompt marks were
+  written as console side effects, which the console host prints before a
+  prompt function's returned text, so the command-start mark landed before the
+  visible prompt: entries read like `\PS C:\Users\you> cd`, and Load inserted
+  that whole text. The marks are now embedded in the returned prompt string in
+  FinalTerm order, so entries contain only what you typed, Load inserts only
+  the command, and completed commands resolve to ✓/✕ status instead of
+  staying Unknown.
+- **No progress bar at an idle prompt.** A shell-integrated pane no longer
+  animates the Visual Progress bar while waiting for input; the bar appears
+  when a command actually executes and clears at the next prompt.
+- **No phantom Timeline row.** The active prompt no longer produces a
+  `Command text unavailable` / `Running` entry. An entry appears when a
+  command executes.
+- **No row jitter.** Moving the selection with the arrow keys or hovering
+  with the mouse no longer makes Timeline rows jump; selection changes reuse
+  the existing rows.
+- **Quieter startup under strict antivirus.** If an antivirus engine blocks a
+  module component at parse time (observed for `Compatibility.ps1`), the
+  session no longer shows a red parse error. The component is skipped, the
+  optional compatibility commands are simply absent, shell integration still
+  works, and `Get-WinTermShellDiagnostics` reports the redacted failure.
+
+## Command Timeline overview
+
+The Command Timeline is a per-pane, in-memory list of the commands that pane
+has run, built from OSC 133 shell integration only. Open it with `Ctrl+Tab`,
+or with the thin handle on the left edge of the terminal. Bare PowerShell
+profiles get shell integration automatically; see the
+[1.3.0-alpha2 release notes](https://github.com/HelloThisWorld/winTerm/releases/tag/v1.3.0-alpha2)
+for the auto-integration rules and the
+[1.3.0-alpha1 release notes](https://github.com/HelloThisWorld/winTerm/releases/tag/v1.3.0-alpha1)
+for the full keyboard map.
+
+## Settings
+
+```json
+{
+  "commandTimeline.enabled": true,
+  "commandTimeline.historyLimit": 500
+}
+```
+
+Per profile:
+
+```json
+{
+  "shellIntegration.autoInject": true
+}
+```
+
+An existing settings file needs no migration.
+
+## Privacy
+
+- Command text lives only in memory, only in the pane that ran it, and only
+  while that pane is open. Nothing is written to disk; there is no command
+  history file or database.
+- Command output is never cached, indexed, or searched.
+- Filter text is never saved and never leaves the pane.
+- No telemetry is written, and no command, output, path, or filter text is
+  logged.
+- The clipboard is written only by an explicit copy action, and is never read.
+
+See the [privacy policy](https://github.com/HelloThisWorld/winTerm/blob/main/PRIVACY.md).
+
+## Unchanged in this release
+
+Workspace schema (2), docking model (1), shell protocol (1), theme schema (1),
+update manifest schema (1), package identity, and signing policy are all
+unchanged from v1.2.0.
+
+## Known limitations
+
+- The Timeline requires OSC 133 shell integration; it stays unavailable under
+  `cmd.exe`.
+- A multi-line command is refused when the shell has not enabled bracketed
+  paste, because unbracketed line breaks would be read as pressing Enter.
+- Loading a command longer than 1024 characters asks for a confirming `Enter`.
+- Command history does not survive closing a pane, and is intentionally never
+  persisted.
+
+## Installation
+
+The Setup EXE supports current-user and all-users installation; the Portable
+ZIP can be extracted to a writable directory and run without installation.
+Installing alpha3 over an earlier alpha is supported; the file version
+advances to `1.3.0.2`.
+
+Publisher: `helloThisWorld`. Tag: `v1.3.0-alpha3`.
+
+## Signing
+
+The winTerm 1.3.0-alpha3 Setup EXE is not Authenticode-signed. Windows may
+display Unknown Publisher or a SmartScreen warning. Download only from the
+official GitHub Release and verify the file against `SHA256SUMS.txt` before
+running it.
