# ADIOS2 v2.12.1 Release Notes
Bug Fixes
SST: NFS Negative Dcache Invalidation
Fixed a race condition on NFS-mounted filesystems where SST readers would fail

to open the writer's contact file even after it was created. A failed fopen()

populates the NFS client's negative dcache; subsequent retries returned NULL

for up to acdirmax (~30 s) despite the file existing. The fix forces a

readdir() on the parent directory before each retry to invalidate the stale

cache entry.
bpls: Double-Precision Min/Max Formatting
Fixed bpls displaying double-precision min/max values as integers when the

value had more than 6 significant digits (e.g., 130255.32345 was shown as

130255). Values outside the range [-10000, 10000] are now printed in

scientific notation (%e). This also affects the Min and Max strings

returned by io.AvailableVariables() in the Python bindings.
Dill: arm64 Linux Support
Resolved a Dill build/runtime failure on arm64 Linux systems.
Improvements
BP5: Vectorized Min/Max Statistics
The min/max statistics computation in BP5 has been vectorized, reducing the

overhead of StatsLevel=1 on large CPU-side buffers. This benefits workloads

such as GPU-simulation codes that write large arrays from host memory.
MGARD: Configurable Lossless Compression Type
A new lossless_type operator parameter lets users choose between huffman

and huffman_zstd for MGARD's internal lossless stage. The default remains

huffman_zstd for backward compatibility.
SST/CXI: Improved Slingshot Error Messages
Error messages from the CXI/Slingshot fabric transport are now more

descriptive, making it easier to diagnose connectivity issues on HPE Slingshot

networks.
