Release of Polars 2.0

Polars 2.0 is a meaningful upgrade for data and analytics teams because it defaults LazyFrame execution to a streaming engine and enables spill-to-disk out of the box, which can materially reduce memory pressure, improve resilience on large workloads, and speed up many queries. The release also elevates SQL to a first-class workload and adds core performance improvements that position Polars as a stronger option for high-performance analytics pipelines, with implications for platform teams standardizing on faster, more scalable data processing stacks. For IT organizations, the key takeaway is that existing jobs may see different row-order behavior unless explicitly preserved, so governance, testing, and workload validation become more important during adoption.
