UPDATE: The Linux and ChromeOS builds have been updated to 1.4.7.1 due to a bug in the application launcher. In specific locales the launcher application was unable to establish the libc version. This has now been fixed.
Overview
This version is specifically a maintenance release which fixes bugs that have been reported since the release of 1.4.5.0. Most significantly, the bug which caused AstroDMx to fail to start on Ubuntu 22.04 and Fedora 36 has been fixed in this release. Various dependencies have also been updated and there is an improved feature in this release.
Improved Feature in the FITS metadata
The FITS metadata now shows the exposure start time with millisecond precision. Previously, the exposure start timestamp was written after the exposure finished but now the timestamp is created just before the camera starts exposing. In addition to this, the value written is zero padded.
Specific Bugs Fixed in this Release
- The version of libstdc++.so.6 distributed with AstroDMx was not compatible with Ubuntu 22.04 and Fedora 36. This has been corrected in this release.
- The bug which caused the camera connect dialog to appear when manually entering specific control values has been fixeed.
Updated Dependencies and Install Location
There have been significant updates to some of the dependencies required by AstroDMx. The updated dependencies are as follows. These dependencies are statically compiled so the user does not need to update anything on their system.
- wxWidgets has been updated from 3.1.5 to 3.1.6. Ultimately, this will aid in the use of Wayland display protocol (Linux) which should be available in the near future. The Raspberry Pi builds of AstroDMx are still using 3.1.5.
- cfitsio has been updated to 4.1.0 for all builds.
- The QHY SDK has been updated to 22.04.20 for all builds.
On Linux, AstroDMx now installs into /opt/AstroDMx-Capture instead of the old location which was /usr/local/AstroDMx_Capture.
General Information
There have been significant code changes in this release which will facilitate the implementation of INDI mount, camera and filter wheel support. INDI support will be released in due course.
Known Issues
There seems to be an issue with the QHY SDK which sometimes causes a segmentation fault if the camera becomes disconnected. This issue will be reported to QHY and a maintenance release will be made once a new SDK is made available by QHY.
