Rolling release PR for Thursday 2026-10-15 (candidate, not yet published)

Version 0.8.1.dev0 -> 0.9.0 in pyproject.toml, envs/grid_world_env/uv.lock and tests/validation_runtime/uv.lock (openenv stanza only).

Merge with gh pr merge <N> --squash --subject "Release OpenEnv 0.9.0 (#<N>)" and an exact-head guard.

Why minor (needs Ben's confirmation by Wednesday)

New public API since v0.8.0: Environment.render_web() and Environment.web_actions() (#1363). Precedent: public API additions -> minor (0.8.0 / #1181). #1292 also scheduled the opencode_env/pi_env removal for 0.9.0 (envs are not in the wheel). If Ben prefers a patch, change to 0.8.1.

Changes since v0.8.0 (src/ delta, 18 files)

• Web UI: simpler visual default playground, real client class/URL/action fields in Quick Start, functools.partial env factories (Web UI: a simpler, more visual default playground #1363, Web UI Quick Start: the env's real client class, URL and action fields #1359, Instantiate functools.partial env factories in the web interface #1364, Fix web playground follow-ups (#1363, #1359) #1378, Follow-ups to #1368, #1369, #1347 and #1363 #1379)
• CLI: openenv push deletes remote Space files only with --delete <pattern>, like hf upload / no models.py requirement (openenv push: remove stale Space files and skip build artifacts #1365, openenv push: don't require models.py (MCP envs like echo_env) #1356, Keep user-added and excluded files when pushing to a Space #1377, openenv push: delete remote files only with --delete, as hf upload does #1413); openenv init template fixes (Fix openenv init template: server --port, next steps and image tags #1374)
• openenv collect: fix "Event loop is closed" with a model teacher (Fix "Event loop is closed" in openenv collect with a model teacher #1367)
• GitServerClient git config kept out of the user's home (Keep GitServerClient git config out of the user's home #1375); HF sandbox provider tweak
• Web UI: long numeric arrays shown as their shape, render_web/web_actions also get reward and done, playground polish, README without the Space front matter (Show big arrays as their shape in the web playground #1398, Polish the web playground: quick-action hover, long args, required choices, README order #1401, Hide the Space front matter in the playground README #1428)
• Client: headers= on EnvClient, e.g. a token for a private Space (Let clients send headers, e.g. a token for a private Space #1403), and CAPACITY_REACHED is reported when the server closes before the first send (Surface CAPACITY_REACHED when the server closes before the client's first send #1402)
• Env servers and the openenv init template parse --host/--port inside main() (Parse --host/--port inside server main() for envs and import templates #1388)
• Envs (not in the wheel): playground drawings for 14 envs, concurrent sessions on 9 envs, chess memory leak and pelican event loop fixes (Fix a chess memory leak, pelican_svg blocking the event loop, and the one-session cap on 9 envs #1404), one BrowserGym thread (Run every BrowserGym call on one dedicated thread #1399), a free Unity port per instance (unity: give each env instance its own communication port #1411), CARLA advances simulation time on the server per tool ([carla_env] Advance simulation time per tool on the server #1412, breaking for clients that sent extra observe steps)
• Many docs, env fixes (not in wheel), workflow hardening (fix(ci): harden GitHub Actions workflows (#1376) #1380, Default HF deploy workflow to the latest stable release tag #1376)

State (Tuesday 2026-10-13 catch-up; Monday run left no trace)

• Base main 8d3455ab; head 38147d03.
• Local: uv build OK, twine check PASSED, clean-venv install of the 0.9.0 wheel imports and openenv --help OK.
• NOT yet done: CI on this head, TestPyPI validation, echo reset/step smoke, merge-main refresh (branch must be up to date with main before merge).
• Known blocker-free defect carried over: uv lock --check fails in the two root-pinning locks (jsonschema, Run Level 2 validation probes #1181); uv sync --frozen passes.
• Dependabot PRs (chore(deps): bump datasets from 4.8.5 to 5.0.1 in /envs/openapp_env #1316, chore(deps): bump gradio from 6.12.0 to 6.16.0 in /envs/reasoning_gym_env #1317, chore(deps): update fastmcp requirement from <4.0.0,>=3.0.0 to >=3.0.0,<5.0.0 #1331 fastmcp<5, chore(deps): bump pyjwt from 2.14.0 to 2.15.0 in /tests/validation_runtime #1335, chore(deps): bump fsspec from 2026.3.0 to 2026.6.0 in /envs/websearch_env #1336, chore(deps): bump fsspec from 2026.3.0 to 2026.6.0 in /envs/textarena_env #1344) not triaged yet; left for the Wednesday/Thursday runs.
• No release lock yet; no PyPI/tag action taken.

Note

Low Risk
No runtime or API code changes in the diff—only version metadata and lockfile pins for packaging.

Overview
Bumps the published openenv version from 0.8.1.dev0 to 0.9.0 for the Thursday rolling release.

The canonical version in pyproject.toml is updated, and the editable openenv package entries in envs/grid_world_env/uv.lock and tests/validation_runtime/uv.lock are aligned so those environments resolve the new release when locked.

Release state, Wednesday 2026-10-14 (supersedes the 'State' section of the PR body, which I cannot edit).

• Candidate head: d00057de = main fc489422 + 3 version lines (0.9.0 in pyproject.toml, envs/grid_world_env/uv.lock, tests/validation_runtime/uv.lock). Diff vs main is only those lines.
• CI on this exact head: 13/13 green (+ docs build skipped as usual).
• Package: uv build + twine check PASSED; clean-venv install of the wheel imports, Environment.render_web/web_actions present, openenv --help OK.
• Echo smoke from the clean install: /health healthy, reset, list_tools (2 tools), step(echo_message) OK.
• TestPyPI 0.9.0.dev201 (run 38520256302 on scratch branch testpypi/0.9.0): wheel is byte-identical to a local build of the candidate (205 members, zero differences).
• Version: 0.9.0 (minor) because of new public API (Environment.render_web/web_actions, #1363). Waiting on Ben only if he wants 0.8.1 instead.
• #1346 (opencode_env/pi_env removal) is NOT in this candidate (conflicts, breaking, needs a human decision); it is outside the wheel.
• Merge on Thursday with gh pr merge 1418 --squash --match-head-commit <head> --subject "Release OpenEnv 0.9.0 (#1418)" after re-checking main has not moved.
• Known, not blocking: uv lock --check fails in the two root-pinning locks (jsonschema from #1181); uv sync --frozen passes.

Alignment Review Report

Automated Checks

• Lint: PASS — the PR's actual diff (pyproject.toml, envs/grid_world_env/uv.lock, tests/validation_runtime/uv.lock) touches no .py/src//tests/ content, so neither usort/ruff format/ruff check apply to any changed line. Ran them anyway in a pristine worktree at the head commit (1ebdb7f7): the only hits are pre-existing noise unrelated to this diff — usort flags the two long-standing files (tests/envs/test_grid_world.py, tests/envs/test_julia_env.py) and ruff format flags a stale Markdown code-fence in src/openenv/core/harness/README.md — none of these three files are touched by this PR.
• Debug code: CLEAN — check-debug.sh only scans src/, which this PR doesn't touch at all; the hook's hits are all pre-existing CLI/example output unrelated to this change.

Diff summary

Pure version-bump release PR, 3 files / +3 -3: pyproject.toml (0.8.1.dev0 → 0.9.0) plus the matching editable-openenv pin in envs/grid_world_env/uv.lock and tests/validation_runtime/uv.lock. No runtime, API, or dependency-constraint changes.

Verified:

• No stale 0.8.1.dev0 references anywhere else in the repo (rg -g '!**/*.lock' '0\.8\.1\.dev0' → 0 hits).
• src/openenv/__init__.py::__version__ is derived from installed package metadata, not hardcoded — nothing else to bump.
• pyproject.toml's version = "0.9.0" parses correctly via tomllib.
• Tag history (v0.2.3…v0.8.0) confirms v0.9.0 hasn't been cut yet, consistent with the PR body's "candidate, not yet published" framing.
• gh pr checks 1418: all CI jobs that apply are green (Analyze ×2, package build/smoke-test, Docker runtime validation, check-env-docs, lint, test 3.11/3.12, tau2/thinkingbox envs, validate-env-locks, snapshot); only Bugbot and the separate "Pre-review" automation are still pending, and build is an expected skipping.

Open RFCs Context

Scanned rfcs/ (000, 001, 002, 003, 004, 005, 006, 008, 010, 011, 012 — several still Draft/In Review). None govern packaging, versioning, or the PyPI release process — this stays true for this PR. Per INVARIANTS.md's Breaking Change Policy, OpenEnv is pre-1.0 but already tracks semver intent; a MINOR bump for the new public Environment.render_web()/web_actions() API (added since v0.8.0, per the PR body) is the correct call under that policy, not a violation of anything.

Tier 1: Fixes Required

None.

Tier 2: Alignment Discussion

Principle Conflicts

None identified. No Gym-API signature, client/server import boundary, reward computation, or MCP/WebSocket surface is touched.

RFC Conflicts

None identified. No open RFC covers packaging/versioning/PyPI release process.

Summary

• 0 mechanical issues to fix
• 0 alignment points for human review
• 0 RFC conflicts to discuss

Clean, well-formed release-prep PR — same low-risk profile as prior weekly release PRs in this repo.
