 # Changelog
 
+## 1.4.0-beta - 2026-08-13
+
+Beta prerelease of the Pane Search release. Manual validation of
+v1.4.0-alpha passed — live search under sustained log output (Kafka /
+Spring Boot workloads), match navigation, the counter, and the scrollbar
+overview all behaved — so the alpha is promoted to beta with beta version
+metadata (package version `1.4.0.1`, prerelease suffix `beta`) and no code
+changes. Published as a GitHub prerelease; the new stable v1.3.0 holds
+GitHub Latest, and this beta replaces v1.4.0-alpha as the newest published
+prerelease. Beta feedback decides the stable 1.4.0 promotion.
+
+## 1.3.0 - 2026-08-13
+
+Stable release of the **Command Timeline** and **Visual Progress**
+generation, promoting the field-tested v1.3.0-beta3 build to the stable
+channel from the `release/v1.3.0` maintenance branch. GitHub Latest moves
+from v1.2.0 to v1.3.0; content is identical to v1.3.0-beta3 apart from the
+stable version metadata (package version `1.3.0.7`, no prerelease suffix).
+Highlights since v1.2.0: the per-pane Command Timeline (`Ctrl+Tab` or the
+left-edge handle) built exclusively from OSC 133 shell integration with
+load-without-executing, filtering, copy command/output, jump to output,
+and trustworthy ✓/✕/Running status; automatic PowerShell shell
+integration for bare `powershell.exe`/`pwsh.exe` profiles; and the Visual
+Progress hardening from six prerelease field-testing rounds, including
+the bounded one-shot launch fallback for long-running commands.

+# winTerm 1.4.0-beta
+
+**This is a beta prerelease.** The current stable release is
+[v1.3.0](https://github.com/HelloThisWorld/winTerm/releases/tag/v1.3.0),
+and `/releases/latest` points there. The beta is published as a GitHub
+prerelease with the standard asset layout; it is not submitted to WinGet.
+
+winTerm 1.4.0-beta is the beta of the **Pane Search** release. Manual
+validation of v1.4.0-alpha passed — live search under sustained log
+output (Kafka / Spring Boot workloads), match navigation, the counter,
+and the scrollbar overview — so the alpha build is promoted unchanged
+with beta version metadata.
+
+## Pane Search
+
+`Ctrl+F` opens Find in the **active pane only** (`Ctrl+Shift+F` stays as
+a compatibility alias; both chords are remappable). The proven Microsoft
+Terminal search pipeline is reused end to end — no second engine, no
+index, no buffer duplication.
+
+- **Search that follows your typing.** Results update live while you
+  type, across the pane's entire scrollback, with every match
+  highlighted at once. `Enter` / `Shift+Enter` step through matches with
+  wrap-around; case-sensitive and regular-expression modes are one
+  toggle away; `Esc` closes and returns focus to the shell.
+- **The winTerm search box.** Compact overlay with a search glyph, the
+  input, a `current / total` match counter, case/regex toggles,
+  previous/next, and close — adapting to narrow panes while always
+  keeping the input and the close button usable.
+- **A scrollbar search overview.** One marker per matching buffer row
+  across the full scrollback, the current match's row emphasized at
+  double width, independent of the `showMarksOnScrollbar` setting, and
+  fully pane-local in splits.
+- **Built for real workloads.** Coalesced live typing, convergence while
+  output streams continuously (`tail -f`, dev servers, Kafka logs),
+  bounded scrollbar repainting with huge match counts, and deterministic
+  safety across pane resize/reflow, scrollback eviction,
+  alternate-screen applications, wide characters (CJK, emoji), and
+  invalid regular expressions.
+
+## Everything in v1.3.0 is included
+
+The Command Timeline, automatic PowerShell shell integration, Visual
+Progress, Workspaces, pane management, themes, and portable mode ship
+unchanged from the new stable release.
+
+## Downloads
+
+- `winTerm-1.4.0-beta-setup-x64.exe` — current-user or all-users
+  installation.
+- `winTerm-1.4.0-beta-portable-x64.zip` — extract and run without
+  installation (creates `portable.marker` alongside the executable).
+- `SHA256SUMS.txt` — checksums for both application assets; verify
+  before running.
+
+Upgrading from any earlier version installs over the existing
+installation and keeps settings, themes, workspaces, and snapshots.
+
+Requires Windows 11 x64. winTerm is an independent open-source project
+based on Microsoft Terminal source code; it is not a Microsoft product
