## Release v0.51.256 — Release HX (stage-r4)
Performance — bound WebUI memory growth & idle CPU on large installs.
### Fixed
| Issue | Author | Fix |
|-------|--------|-----|
| #3506 | @nesquena-hermes (reported w/ profiling by @djenttleman) | On a large install (~615 sessions / 40k messages / 454 MB state.db) the WebUI process climbed ~100 MB → ~1.5 GB RSS over days and held high idle CPU. Three root causes fixed: (1) `session_lifecycle._sessions` grew unbounded → new `discard_session()` drops the entry at agent-eviction boundaries, only when no in-flight commit / no uncommitted memory work (retry invariant preserved); (2) cache caps now operator-tunable (`HERMES_WEBUI_AGENT_CACHE_MAX` default 50→25, `HERMES_WEBUI_SESSIONS_MAX`); (3) GatewayWatcher computes a cheap fingerprint before the expensive per-session `MAX(messages.timestamp)` projection and only re-projects on change. |
### Rebase + review notes
- Rebased onto current master; the code diff was verified **byte-identical to the nesquena-APPROVED head** at rebase time (only CHANGELOG re-resolved).
- The Codex regression gate then surfaced **two correctness gaps** the approval didn't catch, both fixed here with regression tests:
1. **Watcher fingerprint missed same-count transcript rewrites.** `/retry`,`/undo`,`/compress` (`SessionDB.replace_messages`) rewrite messages with new timestamps but can leave `message_count` unchanged → stale sidebar `last_activity`. Fixed with a **per-session** grouped message aggregate (`id, count, user_count, MAX(timestamp)`) over the same non-excluded sessions (a global MAX would miss a rewrite of an older, non-newest session); cron/webui stay excluded so idle churn still doesn't re-project.
2. **LRU agent-cache eviction could close a live worker's agent** (`popitem(last=False)`, liveness-blind — pre-existing, but the lower 50→25 cap made it more likely). Eviction now snapshots `ACTIVE_RUNS` session_ids (before the cache lock — no nested lock) and skips live sessions, deferring (temporarily exceeding cap) rather than closing a live agent.
### Gate
- Full pytest suite: **7612 passed, 0 failed** (one boot-cascade flake re-run; clean on re-run)
- ruff: CLEAN · Codex (regression): 4 rounds → both gaps + a stale test fixed → **SAFE TO SHIP**

## Release v0.51.252 — Release HT (stage-q24)
Two trivially-safe @rodboev changes (independent).
### Fixed
| Issue | Author | Fix |
|-------|--------|-----|
| #2481 | @rodboev | The floating "selected-text reply" button now has `user-select:none`, so its own label can't get caught in a text selection (no bleed-through). CSS one-liner. |
### Docs
- README **Compatibility** section: upgrade WebUI + hermes-agent together until the stable agent API (#2491) lands. (@rodboev)
### Dropped from this batch
- **#2977 `/use` skill command** was staged here but **dropped** — the Codex regression gate found an async stale-directive race (`cmdUse()` awaits `/api/skills` but `send()` doesn't await the handler → a fast next send can miss it, or a stale directive leaks to a later message) plus an over-eager `finally` clear that silently discards the directive on a local slash-command early-return. Held with `changes-requested` + a detailed rework note (tracked pending promise + clear-on-consume). Concept approved; needs lifecycle hardening.
### Gate
- Full pytest suite: **7570 passed, 0 failed**
- ESLint: CLEAN · ruff: CLEAN · browser-smoke: CLEAN
- Codex (regression): **SAFE TO SHIP** — `user-select:none` scoped to the button only, README docs-only, no `/use` code remains

Information-architecture pass on the 840-line README so the most important
things come first and secondary/niche content is linked rather than inline:
- Reorder: Why -> Quick start -> FEATURES (was at line 502, now right after
Quick start) -> Configuration & access -> Docker -> Running tests ->
Architecture -> Docs -> Contributors. Readers see what it does before the
deployment minutiae.
- Consolidate the scattered access sections (start.sh discovery, overrides,
remote/SSH, Tailscale, manual launch) under one '## Configuration & access'
H2 with H3 subsections.
- Extract two genuinely-niche blocks to new linked docs (nothing deleted):
- docs/advanced-chat-setup.md — dynamic recall-prefill + Gateway-backed chat
- docs/remote-access.md — SSH tunnel + Tailscale + ARM64-Android field report
Quick start keeps a one-line pointer to each.
- Update Contents TOC + Docs index for the new order and new files.
README 840 -> 705 lines; content preserved (verified moved-not-dropped); all
internal links + new docs verified to resolve; docs/*.md gitignore-allowlisted.
- ROADMAP.md: 8-themes -> 11-skins in status snapshot; replace stale per-file
LOC architecture table with role descriptions + CI gate list (ruff/shard/
browser/docker); note LOC drifts.
- ARCHITECTURE.md: refresh File Inventory — drop chronically-stale per-file LOC,
add missing modules (state_sync.py, updates.py, i18n/login/icons/sw.js,
pyproject.toml, ctl.sh, CONTRIBUTORS.md), refresh test count to ~7,150.
- README.md: update the 8 'Notable contributions' blurb headers (PR counts +
release ranges) to match the regenerated tally.
Regenerate CONTRIBUTORS.md + README contributors section from a verified
3-source union: GitHub merged-PR list, CHANGELOG.md attribution lines, and
Co-authored-by trailers on master commits (the canonical signal for a CLOSED
contributor PR whose commits were cherry-picked/absorbed and attributed).
- New tally: 194 contributors / 843 PR credits (was a stale 137 / 646).
- The increase: ~135 releases since the v0.51.58 pin PLUS newly-detected
absorbed-CLOSED PRs the prior hand-count missed (e.g. franksong2702 148 =
129 merged + 19 cherry-picked-and-attributed).
- UNION with the existing hand-curated file as a floor: 27 old contributors
had no machine-readable signal (very old closed PRs) — preserved, ZERO dropped.
- Refreshed special-thanks PR counts to match.
- Generator committed to the maintainer workspace as scripts/regen_contributors.py
(--merge-existing keeps it safe for all future refreshes).
Verified: every one of the original 137 logins still present (+57 new).
README:
- Add a Contents table of contents for navigability (800-line doc).
- Freshen stale snapshots: test count 5303/488 files -> ~7,150/~700 files;
reframe contributor counts to point at CONTRIBUTORS.md as the live source.
- Rebuild the Architecture section: drop per-file exact LOC (drifts every
release -> chronic staleness) in favor of a stable backend/frontend role map;
add pyproject.toml + the ruff/browser/docker CI gates.
- Reorganize the Docs index by purpose (Start here / Using / Deploying /
Contributing & design / Release history); add missing CONTRIBUTING.md,
DESIGN.md, docs/workspace-git.md; convert bare paths to working links.
ARCHITECTURE.md: header v0.51.54/5303 -> v0.51.192/~7,150 + note that the
numbers are a periodic snapshot (authoritative source = git tag + collect-only).
TESTING.md: header + footer test counts refreshed; drop the stale
'through v0.50.21' framing; note the ruff/browser/docker gates.
ROADMAP.md: refresh the 'Last updated' stamp (v0.51.31/5028 -> v0.51.192/~7,150)
with recent themes.
Markdown-only; all internal links verified to resolve.
Squashed from 3 author commits onto current master (3 base commits from
already-shipped #2783 were filtered out by the squash). #2805's expanded
candidate-path discovery + PathType Container check preserved from prior
stage commit.
Authorship preserved. CHANGELOG entry merged into batch stamp commit.
Add a narrow README note for the community ARM64 Android AVF field
report: Hermes Agent + WebUI running inside a Debian 12 VM on a
mid-range Android phone with cloud-hosted inference.
The note frames the report as a compatibility signal rather than an
official support baseline or provider/model benchmark, and records
practical mobile caveats around first-install compile time, Android
tab reloads, and battery optimization.

Update CONTRIBUTORS.md and the README contributors section to reflect
130 contributors and 568 PR credits as of v0.51.44 (was 66/142 at
v0.50.245). The numbers grew because:
- The previous refresh was 1 release-cycle ago (50+ tags + 8 batch
releases of contributor PRs ago).
- The new counting rule explicitly includes closed-but-absorbed PRs:
PRs whose original branch shows "closed" on GitHub but whose content
shipped via batch-release squash with a Co-authored-by trailer, or
via salvage rewrite with CHANGELOG attribution. This better reflects
what users actually contributed.
The compilation pipeline:
1. Pull every closed PR from gh api (state=closed, both merged and
unmerged on GitHub) — 1421 PRs.
2. Walk CHANGELOG.md release-by-release and extract:
- `PR #N by @user` (canonical bullet form)
- `(#N by @user`, `(PR #N by @user`, `(#N, @user;`
- `PRs #A, #B by @user` (plural)
- `@user — PR #N`, `@user — N PR (#A, #B)`
- `(credit: @user)` and `(credit: @userA and @userB)`
3. For every PR# mentioned in CHANGELOG, union the explicit @-attributed
users with the gh PR author (when external). Maintainer accounts
(@nesquena, @nesquena-hermes) are excluded.
4. For PRs merged on GitHub but not mentioned in CHANGELOG (very early
PRs, non-noteworthy direct merges), credit the gh author.
5. Three salvaged-design contributors not directly in CHANGELOG are
credited in the special-thanks roll: @indigokarasu (#213 →
v0.50.0 design language), @andrewy-wizard (#177 → initial Chinese
locale absorbed into v0.42.0), @zenc-cp (#133 → anti-hallucination
guard absorbed into streaming.py).
Pre-cleaning step strips HTML entities (` ` etc.) before PR# scan
to avoid false matches. PR# regex requires a whitespace/paren/bracket
preceder so identifiers like `--key=123` and `(##10`-style headings
don't pollute the count.
Per-user first/last release computed from:
- For merged-on-GH PRs: the smallest tag whose creator-date is >= the
PR's merged_at timestamp.
- For absorbed PRs: the release section in CHANGELOG that explicitly
attributes to the user (or the earliest release that mentions the
PR# if no explicit attribution exists for that user).
CONTRIBUTORS.md sections:
- Top contributors (5+ PRs) — 20 people, ranked
- Sustained contributors (3–4 PRs) — 11 people
- Two-PR contributors — 14 people, flat list
- Single-PR contributors — 85 people, flat list
- How credit is tracked — four paths described
- Special thanks — 11 highlight blurbs
README contributors section trimmed to top-10 table + notable-
contribution blurbs (29 distinct contributors mentioned with concrete
PR numbers). Same data, condensed for the README.
No code changes. Docs only.
Detect IPv6 addresses (containing ':') in QuietHTTPServer.__init__ and set address_family to AF_INET6 before socket creation, fixing EAFNOSUPPORT when binding to :: or ::1.
Also updates the loopback check to recognize ::1 and the container warning to mention :: as the IPv6 equivalent of 0.0.0.0. Documents IPv6 usage in HERMES_WEBUI_HOST env var description.
Closes#1695.
@Patrick-81 reported the bare "AIAgent not available -- check that
hermes-agent is on sys.path" error on a symlinked install (~/Programmes/hermes-agent
linked to ~/hermes-agent). The maintainer's response — three diagnostic
commands plus `pip install -e .` in the agent dir — fixed it for them.
This PR captures both halves of that learning so the next user with the
same shape doesn't have to file a new issue:
1. **Error message diagnostic block.** New helper
`_aiagent_import_error_detail()` in api/streaming.py builds a multi-line
diagnostic when the import fails, including:
- the running Python interpreter
- HERMES_WEBUI_AGENT_DIR (set value, or "(not set)")
- sys.path entries that mention hermes/agent (or "no entries mention..."
— itself a strong diagnostic signal)
- the most-common fix (`pip install -e .` in the agent dir)
- a pointer to docs/troubleshooting.md
The original error message string is preserved as the FIRST line so
existing log scrapers and docs-search keep matching.
Helper is kept as a separate function so it stays out of the hot path
until we actually need to raise — building it on every successful import
would be wasted work.
2. **New docs/troubleshooting.md.** Symptom → Why → Diagnostic commands →
Fix → When-to-file-a-bug template, with one entry to start: the
"AIAgent not available" flow Patrick-81 walked through. Future
recurring failure modes follow the same template. Required a one-line
addition to .gitignore — docs/* is gitignored with an allowlist, and
the new file needed `!docs/troubleshooting.md` to be tracked.
3. **README link.** docs/troubleshooting.md added to the `## Docs` section
so users know where to look first.
13 regression tests in tests/test_1695_aiagent_import_error_detail.py:
9 for the helper output shape (preserves original message line, includes
running python, shows HERMES_WEBUI_AGENT_DIR set/unset both ways, includes
pip-install-e hint, points at troubleshooting doc, lists relevant sys.path
entries when present, says "no entries..." when absent, output is multi-line)
plus 4 for the docs-presence regression (file exists, has the AIAgent
section, includes pip install -e ., describes the diagnostic chain with
readlink + agent/__init__.py verification).
190 streaming/aiagent tests pass after the change. ast.parse on
api/streaming.py clean.
CI failure on prior push was due to the docs/* gitignore swallowing the
new troubleshooting.md file silently — this commit adds the allowlist
entry so the file is tracked.
Combines PR #1428 (UID/GID alignment) with a broader Docker reliability pass
that addresses recurring user reports about compose files not working.
Constituent PR:
- #1428 sunnysktsang - Align agent UID/GID with webui (fixes#1399).
Two- and three-container compose files had agent at UID 10000 (image
default) and webui at UID 1000 (WANTED_UID default), causing permission
denied on shared hermes-home volume. All services now use ${UID:-1000}.
Plus broader Docker UX overhaul:
- All 3 compose files document HERMES_SKIP_CHMOD/HERMES_HOME_MODE escape
hatches inline (the v0.50.254 fix wasn't surfaced for Docker users).
- New .env.docker.example template covering UID/GID, paths, password,
permission handling. UID/GID are uncommented with placeholder values
per Opus advisor (so macOS users don't skim past).
- New docs/docker.md - comprehensive guide: 5-min quickstart, failure
mode table with one-line fixes, bind-mount migration, multi-container
architecture diagram, macOS Docker Desktop VirtioFS note, link to
community sunnysktsang/hermes-suite all-in-one image.
- README Docker section rewritten - clearer quickstart, failure-mode
table, link to docs/docker.md. Stale /root/.hermes references removed.
Plus Opus pre-release advisor MUST-FIX:
- HERMES_HOME_MODE has DIFFERENT semantics in the WebUI vs the agent
image. WebUI: credential-file mode threshold (0640 allows group bits).
Agent: HERMES_HOME directory mode (default 0700). 0640 on a directory
has no owner-execute bit, so the agent can't traverse its own home and
bricks. My initial draft recommended HERMES_HOME_MODE=0640 in agent
service blocks - corrected to 0750 across all 4 surfaces (compose
files, .env.docker.example, docs/docker.md). 3 regression tests pin
the asymmetry.
12 regression tests total in test_v050260_docker_invariants.py.
Full suite: 3627 passed, 0 failed.
Nathan explicitly authorized merge with my own review + Opus only, no
independent review needed.
- New CONTRIBUTORS.md: full ranked credit roll for all 66 contributors
(5+ tiers), with first/latest release versions, single-PR roll, and
attribution methodology. Generated from git log + gh pulls API +
CHANGELOG mention parsing.
- README.md: stack-ranked top-10 contributors table at the top of the
Contributors section, link to CONTRIBUTORS.md for the full list.
Updated test count (1898 → 3309). Refreshed @franksong2702 and
@bergeouss entries to reflect their broader bodies of work (now
the #1 and #2 external contributors).
- ARCHITECTURE.md: removed stale 'tracks upstream v0.50.36' header;
bumped current shipped build to v0.50.245 with current architecture
state notes (streaming-markdown vendoring, byte-range streaming,
configurable-model-badges).
- ROADMAP.md / SPRINTS.md / TESTING.md: header/last-updated bumps to
v0.50.245 and 3309 tests. SPRINTS.md 'Where we are now' section
refreshed for current CLI/Claude parity (~95% Claude parity now).
Generated by aggregating CHANGELOG attribution lines, gh PR API
authors, and CHANGELOG version-section walks. Internal/bot accounts
filtered out.
