# Prosody 0.12 upgrade path — docker images, what it fixes, risks (2026-08-29)
Status: **0.12.6 is the current stable Prosody release, but there is NO official
docker image tag for it.** Upgrading from 0.11.9 fixes two standing problems on
nixg.ru at once: XEP-0356 privileged-entity for the bridge, and UnifiedPush
(`util.jwt` only exists in 0.12+).
## Docker image situation (verified via registry API + pulls)
| Source | Tag | Version | Verdict |
|---|---|---|---|
| `prosody/prosody` (official) | `latest` | **0.11.9** (stale) | official tags stop at 0.11.x; no 0.12 tag exists |
| `prosody/prosody` (official) | `trunk` | unreleased trunk | unstable, not for prod |
| `prosodyim/prosody` (3rd party) | `0.12` | nightly build 236 (2026-04-29) | nightly — NOT a stable release |
| `prosodyim/prosody` (3rd party) | `13.0` | nightly build 98 (2026-06-07) | nightly of next major — no |
| build-your-own | from `https://prosody.im/downloads/source/prosody-0.12.6.tar.gz` (HTTP 200) | **0.12.6 stable** | the correct path |
So `docker pull prosody/prosody:0.12` → `not found`, `prosodyim/prosody:0.12.6`
→ `not found`, `prosodyim/prosody:0.12` exists but is a **nightly** — do not run
nightlies in prod. Only route to a stable 0.12: build a custom image on top of
`prosody/prosody:0.11.9` compiling/installing the 0.12.6 tarball, and re-test.
## What the 0.11 → 0.12 upgrade FIXES (motivation)
1. **XEP-0356 privileged entity (bridge roster/bookmarks).** `mod_privilege` is
**built into 0.12** (modulemanager has `module:send_iq()`). On 0.11 the
community `mod_privilege.lua` from prosody-modules is **written for 0.12 API**
and crashes on 0.11 (`attempt to call method 'send_iq' (a nil value)`), which
breaks privileged IQ → slidge cannot write bookmarks → falls back to sending
a gateway invite for EVERY group → client shows "миллион запросов на
подключение к чату" (see `slidge-flood-invites-and-roster.md`).
2. **UnifiedPush.** `mod_unified_push` needs `util.jwt`, which only exists in
0.12+. On 0.11 it fails to load (`module 'util.jwt' not found`). 0.12 opens
the UnifiedPush route (or stay on XEP-0357 `mod_push` which works on 0.11).
3. Bookmarks/OMEMO/PEP handling improvements.
## Data compatibility & migration
- Prosody's internal storage (data dir) is compatible 0.11 → 0.12; users,
rosters, MUC config survive. No data migration tool needed for this hop.
- Config format is the same Lua; 0.12 adds options but accepts 0.11 configs
(validate with `prosodyctl check config` after the switch).
- `component_secret` per-Component stanza (0.11 behaviour) still works.
## Upgrade procedure (when approved)
1. Build custom image `prosody-012` FROM `prosody/prosody:0.11.9` (keeps Lua,
dirs, entrypoint) + download `prosody-0.12.6.tar.gz`, `./configure
--prefix=/usr --sysconfdir=/etc/prosody --datadir=/var/lib/prosody`,
`make && make install`.
2. Remove the community `mod_privilege.lua` from `./modules` (built-in in 0.12)
— but keep `privileged_entities` config, it is used the same way.
3. `prosodyctl check config` → restart → grep logs for `Error initializing`.
4. Verify slidge: bookmarks now written via XEP-0356 (no more invite flood),
`docker logs icq-slidgram` shows no `PermissionError`/privilege errors.
5. Optional: add `mod_unified_push` (apt prosody-modules now fine) for
UnifiedPush, or keep XEP-0357 `mod_push`.
6. Rollback: pin image back to `prosody/prosody:0.11.9` (data dir untouched).

on 0.12 use the built-in module instead of the community one.
