The short version

What changed, and why it matters

This commit only adds new Bitcoin block header checkpoints to Electrum's built-in chain data files. Checkpoints are hardcoded reference points that help the wallet verify it is following the real blockchain and not a fake one. Updating them is a routine maintenance change; it does not fix a software bug and does not introduce new code behavior. It slightly strengthens protection against certain long-range attacks by extending the known-good chain history.

Recommended action

No immediate action required. Treat as routine maintenance. Users should update to a version containing current checkpoints to benefit from the strongest SPV header verification, but the absence of this update does not create a new exploitable vulnerability.

Security signals we found

01

Hardcoded blockchain checkpoints extended for all supported networks

02

No executable code or cryptographic logic changed

03

No bug fix, privilege change, or input validation change present

04

Routine data update that marginally improves SPV header-chain trust anchoring
