Hello all, Here's the PDL 2.087 release announcement as well as a bonus summary of changes over the past year.
Crossposted from <https://www.reddit.com/r/perl/comments/1by46uj/pdl_2087_released_and_a_summary_of_a_year_of_pdl/> and <https://www.perlmonks.org/?node_id=11158731> (formatted HTML available at both). Cheers, - Zaki Mughal --- A [new release of PDL](https://metacpan.org/release/ETJ/PDL-2.087) is out! It's been about a year since I last posted on here about a PDL release (last was PDL 2.083). A selection of changes since PDL 2.083: - Diab Jerius [reported](https://github.com/PDLPorters/pdl/issues/330#issuecomment-1908972935) that a previous change to `[xyz]vals` to return at least a double had a regression for code that requests an explicit type smaller than that. Fixed in 2.085. Diab Jerius also reported several other edge cases: [1](https://github.com/PDLPorters/pdl/issues/445), [2](https://github.com/PDLPorters/pdl/issues/448), [3](https://github.com/PDLPorters/pdl/issues/466) including a [fix for `vsearch`](https://github.com/PDLPorters/pdl/pull/454). Also, Diab Jerius [modularised the primitive ops tests](https://github.com/PDLPorters/pdl/pull/453) which allows for faster parallel testing. - Harald Jörg [reported](https://github.com/PDLPorters/pdl/issues/436) that large arrays would cause `PDL::FFT` to crash. Fixed by switching from the stack VLAs to heap allocation. Fixed in 2.085. While it is recommended to use `PDL::FFTW3` instead, `PDL::FFT` is bundled with `PDL` for the cases where `PDL::FFTW3` can not be easily installed. - Bas Couwenberg [reported](https://github.com/PDLPorters/pdl/issues/439) and fixed a previously deprecated API in HDF4 which has now been removed and replaced. Fixed in 2.085. As part of the Debian release process, Bas Couwenberg [reported](https://github.com/PDLPorters/pdl/issues/469) a failure on i386. Fixed in 2.087. - Shawn Laffan [provided](https://github.com/PDLPorters/pdl/pull/456) an improvement to `PDL::GIS::Proj` so that it would load correctly on Windows via `Alien::proj`. - Po-Chuan Hsieh [provided](https://github.com/PDLPorters/pdl/pull/443) a build fix for FreeBSD on `amd64`. I also happened to talk to James E Keenan around the same time about PDL builds on FreeBSD so this was followed up by adding [CI testing for FreeBSD](https://github.com/PDLPorters/pdl/pull/446). Fixed in 2.085. - Ryan Egesdahl [provided](https://github.com/PDLPorters/pdl/pull/444) a fix for macOS Ventura which changed the location of GLUT headers. Fixed in 2.085. - Eli Schwartz [reported](https://github.com/PDLPorters/pdl/issues/468) an upstream Gentoo bug when building with LTO that uncovered 64-bit issues in Minuit and Slatec Fortran code. Fixed in 2.086. - `@vadim-160102` reported several issues with stringification: [1](https://github.com/PDLPorters/pdl/issues/458), [2](https://github.com/PDLPorters/pdl/issues/459); one of which uncovered a bug in conversion of ulonglong to Perl scalar. - Karl Glazebrook, `@vadim-160102`, and users from PerlMonks provided valuable reports in tracking down issues with dataflow <https://github.com/PDLPorters/pdl/issues/461>. Fix available in 2.086. - Jörg Sommrey contributed [improved typemap handling](https://github.com/PDLPorters/pdl/pull/464) which allows for using the typemap definitions that are available in Perl's default typemap. Available in 2.086. - Ed has added many improvements to the PP code generator and internal API as well as several new functions. Please see the [Changes](https://metacpan.org/release/ETJ/PDL-2.087/diff/ETJ%2FPDL-2.083#Changes) file for details! Of note are several speed improvements that are inspired by Eric Wheeler's [note about the speed of `sequence()`](https://github.com/PDLPorters/pdl/issues/451). A full list of closed issues and PRs is [here](https://github.com/issues?q=org%3APDLPorters+closed%3A2023-05-01..2024-04-07). Thanks to all the contributors! There are also some things to report from the wider World of PDL: - Jörg Sommrey has released a PDL interface to GLPK (GNU Linear Programming Kit) for mathematical optimization: <https://metacpan.org/pod/PDL::Opt::GLPK>. - The `PGPLOT` distribution now incorporates `PDL::Graphics::PGPLOT` module that was in the `PDL` distribution. The dependencies remain the same. - `PDL::Graphics::Simple` had some small updates to the drivers. This is preparation for splitting the backend engines to their respective backend distributions (not yet released) and defining an API version that the engines conform to. _______________________________________________ pdl-general mailing list pdl-general@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pdl-general
