What's new in 2.11?

This is a major release with new features and lots of bug fixes. The main
highlights include enhanced derived variables, remote data access, GPU
improvements, campaign management overhaul, and advanced compression operators.

Summary

Derived Variables

Support for reader-side computed variables with expression evaluation. This
release adds comprehensive functionality including new mathematical operations
(trigonometric functions, multiplication, division, power) and the
ability to apply derived variables to aggregated arrays.

Remote Data Access Infrastructure

Implementation of XRootD and remote server capabilities enabling distributed
file access. This includes support for remote streaming, metadata caching, and
optimized query handling across networked systems.

GPU and Memory Space Improvements

Enhanced GPU backend support with memory selection adjustments, Kokkos
integration improvements, and bindings for cuPy pointers and torch tensors.
Addresses layout mismatches between user code and device memory.

Campaign Management System Overhaul

Significant updates to campaign tracking using SQLite databases replacing JSON
files, configuration file support, and attribute handling. Includes multi-host
support and improved metadata organization.

Compression and Data Format Advances

New operators including BigWhoop compression and Complex MGARD support. ZFP now
supports 4D arrays, and improved MGARD efficiency through zstd compression of
lossless data portions.

OpenSSF Best Practices

ADIOS2 now adopts OpenSSF (Open Source Security Foundation) best practices
including enhanced security measures, automated vulnerability scanning, and
adherence to industry-standard development practices.
