v2.4.0

The Mempool Open Source Project v2.4.0

This release introduces many cool new features:

• All-new mining dashboard with 7 new mining graphs
• Added "bitfeed style" mempool block visualization
• Improved blocks page that identifies mining pools
• Improved fee suggestions with a "no priority" rate
• And much more!

Out of the ~3400 commits in our git repo, ~1300 were made since v2.3.
Lots of work went into v2.4, and all users are encouraged to upgrade to enjoy this new functionality.

Notes for upgrading from v2.3 if your timezone is NOT set to UTC

If you are upgrading from v2.3 or earlier and you want to migrate your historical mempool statistics database, you will need to do a special update procedure if your server's timezone is NOT set to UTC. How to migrate:

1. Backup your MySQL database.
2. Terminate the mempool backend process.
3. Run the following query to check your mysql connection timezone: SELECT @@global.time_zone, @@session.time_zone;
4. If you get SYSTEM, check your system timezone with the date command.
5. Perform the SQL query with your negative GMT offset: UPDATE statistics SET added=DATE_ADD(added, INTERVAL -2 HOUR); (For example, if your timezone is set to CEST (UTC+2), you need to shift all your statistics entries negative 2 hours.)
6. Proceed with upgrading mempool as usual.
