fstcore 0.9.17 (in development)

fstcore 0.9.16 (2023-11-29)

This release addresses build problems on systems using clang version 16 or above due to the use of string literals in RcppExports.cpp. With thanks to CRAN for identifying the problem and Prof. Eddelbuettel for providing a fix in the Rcpp package.

Library updates

• ZSTD has been updated to version 1.5.5

fstcore 0.9.14 (2023-01-12)

This release addresses build problems on systems using gcc 13 due to missing includes. With thanks to Prof. Ripley for identifying the problem and offering pointers to the solution.

Library updates

• LZ4 has been updated to version 1.9.4

fstcore 0.9.12 (2022-03-23)

This release adds a fallback mechanism for systems that fail the configure script. When systems packages LZ4 or ZSTD are missing and configuration fails, the bundled code is used to build the package.

fstcore 0.9.10 (2022-03-21)

This release adds a configure script to the package that checks for the availability of system packages lz4, zstd and xxhash. When available, these system packages are used instead of compiling code directly from the package sources.

fstcore 0.9.8 (2022-02-04)

This release addresses linking problems occurring on ARM OSX systems due to incorrect configuration of Makevars. With thanks to Prof. Ripley for identifying the problem and offering pointers for the solution.

Library updates

• ZSTD has been updated to version 1.5.2
• LZ4 has been updated to version 1.9.3

fstcore 0.9.6 (2021-01-05)

With version 0.9.6, the license of fstcore changes from AGPL version 3 to MPL version 2. This allows for less restrictive use of the fstcore package. In particular, closed-source (commercial) solutions can now use fstcore (call it’s API), as was impossible under AGPL (under AGPL, products can only use fstcore if they make the products source code available under AGPL or more restrictive license).

Library updates

• ZSTD has been updated to version 1.4.5
• fstlib has been updated to version 0.1.6

Enhancements

• Numeric values can now be used to select a row range, including values larger than 2^31 to select a subset from long vector columns (thanks @dipterix for reporting)
• The random seed is not initialized anymore when fstcore is loaded (see fst#251, thanks @mlell for investigating and @riccardoporreca for providing the solution)

fstcore 0.9.4 (2020-05-04)

R package fstcorecontains the R bindings to the C++ fstlib library needed to interface with fst files as well as the LZ4 and ZSTD sources. It was developed as a package separate from the fst package to facilitate independent updates to the fstlib, LZ4 and ZSTD libraries.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
