## [0.3.4] - 2026-03-27

### Added
8
+
9
+
- **Nanoclaw sandbox provider**: New Cloudflare-based `nanoclaw` sandbox deployment with its own Dockerfile, Wrangler config, and banner.
10
+
- **Volume support for Sprites, Daytona, Deno, and Vercel providers**: All major providers now support volume mounting alongside the existing Cloudflare provider.
11
+
- **`@anthropic-ai/claude-code` in Dockerfiles**: Claude Code is now pre-installed in sandbox images.
12
+
- **`keepAlive` option**: Sandbox APIs now accept a `keepAlive` option to control sandbox lifecycle.
13
+
- **Sandbox reuse by repo and DID**: When a matching sandbox (same repo + DID) already exists, it is returned instead of creating a new one.
14
+
- **GitLab repo expansion**: CLI and web now support GitLab repository URLs in addition to GitHub and Tangled.
15
+
- **`/new` page in web**: New page for creating sandboxes directly from a repository URL.
16
+
- **"Open in Pocketenv" badge**: Added SVG badge and README integration so projects can link directly to Pocketenv.
17
+
- **GitHub downloads badge**: README now shows a download count badge.
18
+
- **VS Code expose button in web UI**: Sandbox detail page now has a button to expose VS Code and open the preview URL.
19
+
- **`folder` param for Cloudflare preview URL**: Preview URL generation now accepts an optional folder parameter.
20
+
21
+
### Changed
22
+
23
+
- **Sandbox creation flow**: Sandbox is now started on create; `sandboxId`, `status`, and `startedAt` are set on start. The `sandboxId` is no longer cleared on stop.
24
+
- **Async repo cloning**: Repository cloning on sandbox creation is now done asynchronously, unblocking the terminal session sooner.
25
+
- **Sandbox configs run in background on start**: Provider config steps are now non-blocking.
26
+
- **Sandbox POST moved outside DB transaction**: Improves reliability of sandbox creation under load.
27
+
- **s3fs options**: `compat_dir` option enabled; `s3fs` is now exec'd directly for volume mounting.
28
+
- **Sandbox instance type**: Upgraded to `standard-3` for improved performance.
29
+
- **Zerobrew setup**: Zerobrew binaries moved to root `~/.local/bin` and installed consistently across sandbox, Daytona, and Cloudflare Dockerfiles. Zerobrew installer script removed in favor of direct binary install.
30
+
- **`node:lts-trixie-slim` base image**: Codex and related sandbox images now use `node:lts-trixie-slim`.
31
+
- **`coder` user added to Codex and CF sandbox Dockerfiles**.
32
+
- **oh-my-posh install combined** with Node version bump to reduce image layers.
33
+
- **Stale sandbox port cleanup**: `sandboxPorts` records are now deleted for stale sandboxes.
34
+
- **`exposeVscode` allows unauthenticated queries** for public (userId-less) sandboxes; AT Protocol agent creation is deferred until the sandbox has an `at://` URI.
35
+
- **Sandbox filtered by base segment** when looking up existing sandboxes.
36
+
- **Sandbox start retries removed**: Retry wrappers and readiness waits have been simplified; sandbox is started once before opening the terminal session.
37
+
38
+
### Fixed
39
+
40
+
- **Terminal rendering issue**: Fixed a CLI rendering bug affecting terminal output (theme.ts).
41
+
- **Volume not correctly mounted on start**: Fixed volume mount logic when starting an existing sandbox.
42
+
- **Sandbox port upsert**: Port record is now inserted if an update hits no rows.
43
+
- **Sandbox port deduplication**: Stale sandbox ports are cleaned up to avoid duplicate entries.
