v1.0.0

First stable release of the Matrix Lightning Tip Bot. The previous 0.9.x line has been promoted to 1.0 after a larger round of hardening, an SDK upgrade and a full command regression test against a production MAS-backed Matrix homeserver.

Highlights since v0.9.4

Cross-signing and session persistence

The bot now attaches a sqlite store to the matrix-sdk client and keeps its device id, access token and crypto state across container restarts. After the first login it bootstraps cross-signing and, importantly, self-signs its own device via Device::verify() so clients stop rendering its messages as "encrypted by an unverified device". Required a new --store-path config option and a volume mount for the crypto directory (see README).

matrix-sdk upgraded 0.12 → 0.16

Three sequential bumps committed separately to keep git bisect useful:

• 0.12 → 0.13: trivial version bump, no source changes required.
• 0.13 → 0.14: compiled through without source changes; ruma bumped 0.12 → 0.13.
• 0.14 → 0.16: one source change — OriginalRoomMessageEvent became #[non_exhaustive], so the reply helper now uses OriginalSyncRoomMessageEvent::into_full_event(room_id) instead of field-by-field construction.

!tip works against modern clients again

Modern Matrix clients follow MSC2781 / Matrix 1.13 and no longer include the <mx-reply> HTML fallback when replying. The bot now follows m.relates_to.in_reply_to.event_id and fetches the original event via Room::event() to discover the tip target, with the old formatted-body parser kept as a silent fallback for legacy clients.

LNbits invoice decode

Modern LNbits returns both payment_request and bolt11 in the same response, which tripped our serde(alias = "bolt11") duplicate-field check. Dropped the alias so only payment_request is consumed. bolt11 is silently ignored. The invoice helper also now surfaces LNbits status + raw response body on any failure instead of returning an opaque reqwest error.

CoinGecko fiat conversion

CoinGecko no longer serves the default reqwest user-agent a usable JSON body, which made !fiat-to-sats and !sats-to-fiat always fail with "Missing conversion rate". The price request now sends an explicit user-agent identifying the bot and logs status + body on any failure.

Developer experience

• Cargo.lock is tracked; all builds now use --locked for reproducible output.
• The Dockerfile builds dependencies in a separate cached layer — changing only src/ no longer recompiles matrix-sdk every time.
• Builder image bumped to rust:1.90.
• Help output collapsed to a single, consistent format (always !command). Removed the old "Don't worry about the red Not verified warning" note now that cross-signing actually self-signs the device.

Breaking config change

--store-path=<dir> is now a required argument. The directory has to be writable and mounted into the container as a dedicated volume; the bot persists session.json, .passphrase and the sqlite crypto store there. See the README for the Docker setup.

v0.9.4

What's Changed

• Display routing fee errors to users instead of generic error message by @warioishere in #51

Full Changelog: v0.9.3...v0.9.4

v0.9.3

• introduce a structured PayError in the LNbits client so failed payments return rich error details instead of always succeeding
• make the Matrix business logic surface LNbits payment failures to users and add an httpmock-based regression test

v0.9.2

• use the async lnurl-rs client when sending to LNURL recipients and deduplicate lnurl parsing
• Avoid panics when parsing formatted messages
• Handle invalid invoice input gracefully
• Guard against empty messages

v0.9.1

• parse bot name from matrix_username rather than the homeserver url
• Use structured command dispatch
• Simplify room member lookup
• Use pulldown-cmark for markdown conversion
• Create reusable async status poller
• if an arugment is missing, bot now replies with the arg that is missing instead of "unknown command"
• remove unused dependencies
• add a little cache for room-members to speed up replies on bigger rooms
• bugfixing

v0.9.0

Add Boltz submarine swaps support for onchain to offchain and offchain to onchain swaps with refund workflow for failed swaps.
