New Papertrail CA bundle next week

Papertrail will be updating **papertrail-bundle.tar.gz** on **Tuesday, May 15**. The new SHA-256 checksum will be `be208e650e910106bc9d6c954807c875b22cd9fbe005aa59e0aad0ed13b0c6b6`, but given that we might continue updating this file from time to time, I'd recommend against simply hard-coding a new checksum. Instead, either omit the checksum entirely, or embed the entire bundle rather than downloading it. Either option ensures that Papertrail is free to update the source without breaking anyone's deployment.
