automerge 0.4.0

CRAN release: 2026-02-26

• am_text_update() no longer requires the old_text argument; the current text content is now read from the document automatically.

• am_text_content() gains a heads parameter for historical text queries.

• Functions accepting a heads parameter now support multiple heads.

• Fixes additional Valgrind false positive in vendored automerge library.

automerge 0.3.1

CRAN release: 2026-02-19

• Adds print() method for am_change objects.

• Removes vendored tinyvec dependency to fix Valgrind false positive.

automerge 0.3.0

CRAN release: 2026-02-17

• Change-returning functions (am_get_changes(), am_get_last_local_change(), am_get_change_by_hash(), am_get_changes_added()) now return am_change objects instead of raw vectors.

• Removes am_get_history(). Use am_get_changes() instead, which returns the full change history when called without heads.

• Renames am_sync_state_new() to am_sync_state().

• Adds change introspection functions: am_change_hash(), am_change_message(), am_change_time(), am_change_actor_id(), am_change_seq(), am_change_deps(), and am_change_size() for extracting metadata from changes. am_change_to_bytes() and am_change_from_bytes() enable serialization round-trips.

• am_cursor(), am_cursor_position(), am_marks(), and am_marks_at() gain a heads parameter for querying at historical document states.

• Adds cursor serialization and comparison: am_cursor_to_bytes(), am_cursor_from_bytes(), am_cursor_to_string(), am_cursor_from_string(), and am_cursor_equal().

• Adds incremental save/load: am_save_incremental() and am_load_incremental() for exchanging only new changes since the last save.

• Adds conflict inspection: am_map_get_all() and am_list_get_all() for retrieving all conflicting values at a key or index after concurrent edits.

• Adds range queries: am_map_range() for retrieving map entries within a key range, am_list_range() for retrieving a subrange of list items, and am_items() for getting all key-value entries from any object.

• Adds am_mark_clear() for removing marks from text ranges.

• Adds sync state serialization: am_sync_state_encode() and am_sync_state_decode() for persisting sync state across sessions.

• Adds am_load_changes() for decomposing saved document bytes into individual changes, and am_get_missing_deps() for checking document completeness.

• Adds document utilities: am_clone() for deep copying (preserving actor ID), am_equal() for testing document equality, am_pending_ops() for counting uncommitted operations, and am_commit_empty() for creating empty changes.

• Updates MSRV to 1.85.
