fastMatMR 1.2.7 (2026-03-01)

Features

• Transparent gzip support for all read/write functions via .mtx.gz file extension (#28)
• Add fmm_to_spam() and spam_to_fmm() for reading/writing spam sparse matrices (#2)

• ASV benchmark infrastructure with CI integration

Bug Fixes

• Require cpp11 >= 0.5.0 to resolve non-API usage of SETLENGTH, SET_GROWABLE_BIT, and SET_TRUELENGTH (cause of CRAN archival)
