The old pattern — build an edit object, remember to push it — had silently failed three separate times, most recently in the file-import path where multiple files shared one…
Second, saving. PR sixteen-six-four-six from koppor tackles concurrent modification: two JabRef instances writing the same shared library file could silently overwrite each other, or even corrupt the file on non-atomic filesystems. The fix snapshots file size and modification time before committing and throws a new…
Third, a run of stale-test fixes: PR sixteen-six-four-four, sixteen-six-six-three, and sixteen-six-six-seven all corrected test expectations after the Library of Congress, RFC Editor, and lobid services changed their live data formats — not code regressions, just drift between production behavior and hardcoded…
