Changelog of 0.6.1 (On the new way with errata) release

Release date: 2. October, 2022.

This release includes minor improvements.

Improvements:

Changelog of 0.6.0 (On the new way) release

Release date: 6. March, 2022.

This release brings the deep redesign of GUI.

Principal changes:

I changed my mind; build principles has been revised to create more handy GUI.

Improvements:

Possible directions:

Changelog of 0.5.14 (Bullseye) release

Release date: 4. February, 2021.

A bugfix release of previous release.

The bugfix

The interface, introduced in latest release, caused run-time crashes under all i386, armhf, armel architectures in Debian nomenclature. An inspection revealed that C_LONG has been associated with C_LONG_LONG, and vice versa, for some routines. It looks like the 32-bit platforms distinguish the types; 64-bit platforms does not. The malfunction has not been detected during previous tests.

The confusion became as result of my blind following of API in the manual (even obsolete), and missing double check against C headers.

Other improvements:

Changelog of 0.5.13 (Bullseye) release

Release date: 21. December, 2020.

An interface of cfitsio library for modern Fortran has been developed in this release.

The improvement:

Autopkgtest (#977559) has reported an issue under arm64 (aarch64) platform for version 3.49 of cfitsio library, whilst amd64 port is unaffected. An incompatibility in passing of integer numerical types between C and Fortran has been revealed for the array argument NAXES of ftgisz() which wraps ffgisz(). The calling of C functions from Fortran, and vice versa, is a complex problem, requiring resourceful C macros and functions, and varying on a specific software platform.

I resolved the issue by building of an interface of cfitsio library for modern Fortran. The interface fully replaces the wrapping parts of cfitsio, and utilises C/C++ interoperability, a part of Fortran standard since 2003 revision.

As the side effect, a speed of I/O operations has significantly increased. I had improved also reading of tables by slicing columns: tables are read in rows-major order, rather than in column-major, according to recommendations in cfitsio manual (13.2 Optimization Strategies, paragraph 3). There are new implementations of the file handling, and the backup.
