Release Note for Neo4j 5.26.10 (4 August 2025)

Bug Fix Fixed Timeout Handling for Large Duration Values This release resolves an issue where extremely large timeout values could cause unexpected behavior or application errors. What was affected:

• Setting very large timeouts
• Potential for incorrect timeout behavior or system errors in edge cases

What we fixed:

• Improved internal handling of timeout duration calculations to prevent numeric overflow
• Enhanced stability when processing large timeout configurations
• Ensured consistent timeout behavior across all supported duration ranges

Action required:

• No immediate action required for most users
• If you previously experienced unexpected timeout behavior with large duration values, this issue should now be resolved

Additional notes:

• This fix applies to all timeout configurations throughout the system
• The fix is automatically applied and requires no configuration changes

This improvement enhances system reliability, particularly for extended timeout periods for long-running operations.
