Issues

• UndoManager: undoing a tree move into or out of a deleted parent creates a new node instead of restoring it

• Tree insert panics in fractional_index new_after (unreachable) with fractional index jitter

• Decoding a deeply nested LoroValue from a small snapshot overflows the stack (unbounded recursion in Deserialize and Drop)

  loro-dev/loro#1198 · Filter by author darti opened on Oct 16, 2026

• First read of a LoroTree from a snapshot with a deep parent chain overflows the stack (recursive get_all_hierarchy_nodes_under)

• importBatch([snapshot, ...updates]) skips the fast snapshot import path

• toContainerTree: return JSON text so a deep read with rich-text deltas crosses the wasm boundary once

  loro-dev/loro#1192 · Filter by author seompark opened on Oct 13, 2026

• Make the decoded container value cache limit configurable (2,048 cap re-decodes large docs on every read)

• Small styled text slices scan expanding anchors outside the requested content

• Clarify map-container deletion undo: restored child identity excludes concurrent edits to the old child

• UndoManager hides diff application errors and consumes failed history items

  loro-dev/loro#1186 · Filter by author maghamalyan opened on Oct 12, 2026

• MovableList undo duplicates an element after concurrent moves and loses removal anchors

  loro-dev/loro#1185 · Filter by author maghamalyan opened on Oct 12, 2026

• One UndoManager::undo call can consume multiple items and revert an unrelated parent container

  loro-dev/loro#1183 · Filter by author maghamalyan opened on Oct 12, 2026

• loro.js 0.3.0: crossing concurrent tree moves leave the tree empty, and the skipped move comes back later

• loro-crdt's declarations fail to typecheck with skipLibCheck: false

• getCursorPos traps (RuntimeError: unreachable) on a decodable cursor with a negative counter, and leaves the document unusable

• Stack overflow in fork_at / checkout after concurrent LoroTree moves

  loro-dev/loro#1117 · Filter by author lightsofapollo opened on Sep 25, 2026

• Zero sum diffs relating to counters are dropped

• getDeepValueWithID: cid strings in Debug format, ~2.2x cost of toJSON

• import() panics when a remote update depends on ops folded into a shallow snapshot; still on main after #1064, and the panic poisons the doc mutex

• forkAt breaks in 1.13.7, no error, browser just locks up when doing fork with frontiers

  loro-dev/loro#1056 · Filter by author jamesgibson14 opened on Jul 27, 2026

• Undoing a post-import LoroTree edit deletes the pre-existing node ID

  loro-dev/loro#1055 · Filter by author srpattison opened on Jul 24, 2026

• checkout() to the frontiers a detached doc is already at re-attaches it (1.13.6 → 1.13.7)

• Movable list panics (unwrap on None at movable_list_state.rs:1210) when a delete and a concurrent edit+move import as separate update batches — 1.13.7 regression

  loro-dev/loro#1046 · Filter by author quantools opened on Jul 18, 2026

• Importing a shallow snapshot into a doc with concurrent ops stalls as permanently pending when the snapshot root is a single-head frontier (multi-head root imports fine)
