Chat 2 has entered a major rework that Infi confirmed makes selective patches no longer portable. The cherry-pick pipeline as a routine workflow stops with the v1.4.x cycle. Documentation reflects the new state across all touchpoints. UPSTREAM_SYNC.md rewritten: replaces the "How I Cherry-Pick" / "Reviewing What Is New Upstream" / "Conflict Handling" sections with "Why Cherry-Picking Stopped", "What Closing the Pipeline Means in Practice", "What Does Not Change", "What Could Re-Open Later". Existing cherry-pick trails in the git history stay intact, EUPL-1.2 anchor lines and NOTICE.md remain canonical. README.md, CONTRIBUTING.md, ROADMAP.md, THIRD_PARTY_NOTICES.md and the PR template updated to match: cherry-pick references reframed as historical or pointed at UPSTREAM_SYNC.md for the current state. NOTICE.md keeps the BetterTTV cherry-pick example as a concrete past case but adds a paragraph that the pipeline is closed and clarifies the attribution standard is preserved unchanged. PULL_REQUEST_TEMPLATE.md drops the "Upstream cherry-pick from Chat 2" checkbox and the cherry-pick-path compatibility prompt. The upstream git remote was already removed locally on 2026-05-08 (separate change, not in this commit). No source-file edits, no manifest version bump, no changelog entry — this is documentation-only and ships with the next release.

Upstream code
HellionChat is a fork of Chat 2
by Infiziert90 (Infi) and Anna Clemens, also licensed under EUPL-1.2.
The bulk of the code, including the message store architecture, the
channel logic, the hook system and the ImGui chat window, originates
from upstream. See ../NOTICE.md for the attribution; UPSTREAM_SYNC.md
documents the upstream-sync history, including the close of active
cherry-picking in the v1.4.x cycle.
Components that touch the network
Of everything listed above, none of the bundled or NuGet
components opens network connections on their own. All outbound
traffic is initiated explicitly by HellionChat's own source files
and is documented in PRIVACY.md under "Outbound network calls":
HellionChat/EmoteCache.cs→ BetterTTV API + CDN (opt-out via setting)
The earlier Square Enix Lodestone font download (FontManager.cs)
was removed in v1.0.4 — it was a leftover from upstream's removed
webinterface feature and was no longer consumed.
Verifying this list
To regenerate the dependency inventory after a version bump:
dotnet list HellionChat.sln package --include-transitive
The "direct NuGet dependencies" table above only lists direct references. Transitive dependencies pulled in by Dalamud SDK or by the listed packages are covered by the SDK / package licences and documented by their respective maintainers.
To re-audit the network-call inventory:
grep -rn -E "HttpClient|HttpRequest|new Uri\(|https?://" \
--include="*.cs" HellionChat/
Any new hit that is not a click-through (Util.OpenLink) or a
payload-parsing call must be added to PRIVACY.md before release.
