+# OK Code v0.13.0
+
+**Date:** 2026-04-04
+**Tag:** [`v0.13.0`](https://github.com/OpenKnots/okcode/releases/tag/v0.13.0)
+
+## Summary
+
+Blur `.env` file contents in the code viewer to reduce accidental secret exposure.
+
+## Highlights
+
+- **Blur `.env` file contents in code viewer.** The viewer now masks `.env` values so secrets are less likely to be exposed during review.
+- **Ship aligned `0.13.0` builds across desktop and mobile packaging.** The release workflow publishes versioned artifacts for all supported platforms.
+
+## Breaking changes
+
+- None.
+
+## Upgrade and install
+
+- **CLI:** `npm install -g okcodes@0.13.0` (after the package is published to npm manually).
+- **Desktop:** Download from [GitHub Releases](https://github.com/OpenKnots/okcode/releases/tag/v0.13.0). This release includes macOS arm64/x64, Linux x64, and Windows x64 assets; filenames are listed in [assets.md](v0.13.0/assets.md).
+- **iOS:** Available via TestFlight (uploaded automatically by the Release iOS workflow).
+
+## Known limitations
+
+OK Code remains early work in progress. Expect rough edges around session recovery, streaming edge cases, and platform-specific desktop behavior. Report issues on GitHub.

+# v0.13.0 — Release assets (manifest)
+
+Binaries are **not** stored in this git repository; they are attached to the [GitHub Release for `v0.13.0`](https://github.com/OpenKnots/okcode/releases/tag/v0.13.0) by the [Release Desktop workflow](../../.github/workflows/release.yml).
+
+The GitHub Release also includes **documentation attachments** (same content as in-repo, stable filenames for download):
+
+| File                        | Source in repo                        |
+| --------------------------- | ------------------------------------- |
+| `okcode-CHANGELOG.md`       | [CHANGELOG.md](../../../CHANGELOG.md) |
+| `okcode-RELEASE-NOTES.md`   | [v0.13.0.md](../v0.13.0.md)           |
+| `okcode-ASSETS-MANIFEST.md` | This file                             |
+
+After the workflow completes, expect **installer and updater** artifacts similar to the following (exact names may include the product name `OK Code` and version `0.13.0`).
+
+## Desktop installers and payloads
+
+| Platform            | Kind           | Typical pattern |
+| ------------------- | -------------- | --------------- |
+| macOS Apple Silicon | DMG            | `*.dmg` (arm64) |
+| macOS Intel         | DMG            | `*.dmg` (x64)   |
+| macOS               | ZIP (updater)  | `*.zip`         |
+| Linux x64           | AppImage       | `*.AppImage`    |
+| Windows x64         | NSIS installer | `*.exe`         |
+
+## Electron updater metadata
+
+| File               | Purpose                                                   |
+| ------------------ | --------------------------------------------------------- |
+| `latest-mac.yml`   | macOS update manifest (merged from per-arch builds in CI) |
+| `latest-linux.yml` | Linux update manifest                                     |
+| `latest.yml`       | Windows update manifest                                   |
+| `*.blockmap`       | Differential download block maps                          |
+
+## iOS (TestFlight)
+
+The iOS build is uploaded directly to App Store Connect / TestFlight by the [Release iOS workflow](../../.github/workflows/release-ios.yml). No IPA artifact is attached to the GitHub Release.
+
+| Detail            | Value                                      |
+| ----------------- | ------------------------------------------ |
+| Bundle ID         | `com.openknots.okcode.mobile`              |
+| Marketing version | `0.13.0`                                   |
+| Build number      | Set from `GITHUB_RUN_NUMBER` at build time |
+
+## Checksums
+
+SHA-256 checksums are not committed here; verify downloads via GitHub's release UI or `gh release download` if you use the GitHub CLI.
