Prosody 0.11 capability matrix (XEP audit) — verified 2026-08-29 on nixg.ru

Checked against config/prosody.cfg.lua + docker exec icq-prosody ls /usr/lib/prosody/modules/

• logs. Use this to answer "is feature X supported?" for a Prosody 0.11.x deployment.

Capability	XEP	How it works in 0.11	Status
MUC (group chat)	XEP-0045	Component "conference.<dom>" "muc" (module is a Component, NOT a host module — loading muc in modules_enabled errors)	✅
PubSub	XEP-0060	mod_pubsub ships in stock BUT in a subdir (/usr/lib/prosody/modules/mod_pubsub/mod_pubsub.lua) and is not loaded by default — add "pubsub" to modules_enabled	✅ (enable explicitly)
HTTP Upload	XEP-0363	community mod_http_upload (NOT stock); Component "upload.<dom>" "http_upload". Stock image has no mod_http_file_share either	✅ (install module)
MAM (history)	XEP-0313	mod_mam (stock) + mod_muc_mam (stock, loads on MUC component)	✅
Carbons	XEP-0280	mod_carbons (stock)	✅
PEP	XEP-0163	mod_pep (stock)	✅
OMEMO	XEP-0384	client-side only in 0.11: no server mod_omemo exists (neither stock nor prosody-modules — verified: mod_omemo 404s on hg). Server role = PEP for key bundles. Gajim/Dino/Conversations/Monal handle the crypto; Converse v14 bundles libomemo	⚠️ client-side
OTR	XEP-0364	also client-side; nothing on the server	⚠️ client-side
WebRTC (calls)	XEP-0166 (Jingle)/0343	Jingle is client-side; no server Jingle module; server just carries c2s/websocket signalling	⚠️ client-side
Bookmarks	XEP-0402 / XEP-0048	via PEP node storage:bookmarks (mod_pep); no separate mod_bookmarks in 0.11 (prosody-modules has mod_default_bookmarks / mod_group_bookmarks if default bookmarks wanted)	✅ via PEP
Recent rosters / roster versioning	XEP-0237	mod_roster versioning	✅
Privileged Entity (bridge roster sync)	XEP-0356	community mod_privilege + privileged_entities on VirtualHost	✅ (install module)
External components (bridges)	XEP-0114	component_ports = { 5347 } + Component stanza with per-stanza component_secret (global component_secrets table ignored in 0.11!)	✅

Key takeaways

• No server-side OMEMO/WebRTC/Bookmarks modules exist for 0.11 — this is normal, not a misconfiguration. Those features are client-side over PEP. Do not hunt for mod_omemo.
• mod_pubsub is stock but off by default — if PubSub/PEP-dependent features are missing, check modules_enabled first.
• Community modules install path from RF: hg.prosody.im (see SKILL.md "Community modules").
• Remember: PEP node for OMEMO bundles requires pep + pubsub both enabled.
