Migrating Pipelines 1/2x steps to our new CI/CD runtime

This post details the migration of Bitbucket Pipelines' 1x and 2x build sizes to the new CI/CD runtime. It explains the shift from shared CPU pools to dedicated CPU allocation, where 1x builds will now show 2 cores (maintaining similar compute levels) and 2x builds will have approximately double the CPU allocation compared to before, aligning with their 2x memory allocation. The migration is scheduled for September 17th, 2024, and requires users leveraging IP allowlisting to update their configurations to the new IP address ranges.
