0.9.21 included a few fixes from the 0.9.19 release, but is otherwise the same release in terms of enhancements and fixes. Below is the release notes applicable for both. If you are on 0.9.19, we strongly recommend upgrading to 0.9.21.
We continue to focus primarily on bug fixes. Please keep the feedback coming if you're seeing other bugs we don't mention below.
iOS 12 performance fixes - Fix issues with focus points not going away when switching between single point and multipoint focus
Fixed issue with some Sony cameras showing up as "Not Supported"
Significantly reduced the amount of time live view stops updating while a shot is downloading on most cameras
Multipoint focus improvements
Canceling points in multipoint focus now stops the focus process faster
Fixed issue where handheld mode could not be started until a few (maybe 10) seconds after the boot. Now you should be able to start handheld mode as soon as the "booted" LED animation plays
Fixed issue with Sony USB cameras connecting in certain modes
Added support for adapted lenses on Sony cameras
Sony cameras now display the correct f-stop numbers for the lens
Fixed a focus issue on Sony wifi cameras
Fixed an issue on some Canon and Nikon cameras where card scanning after the first shot would block too long and cause the device code to crash. (The next release should have a fix where the first shot no longer needs to scan the card at all to get the photo paths)
Fixed an issue with photo paths not being reported on the a6000 on the first shot
Fixed an issue in timelapse on the A6300
Fixed an issue where smart mode would choose an iso below the base iso in certain situations
Fixed issue with parts of timelapse screen not showing correctly on some phones on Android
On Android, changes to the camera dial now update in the slider in manual mode
Fixed an Android issue with removing focus points
Fixed issue on Android with timelapse progress not updating
A few things on the radar for the near future:
We still have a handful of the less used cameras that we need to make improvements on. A few, like the D3100, D3000, you’ll see a ‘camera not supported’ message until we can get them up to par (the experience just wasn’t great on these, and we didn’t want folks trying to troubleshoot or having a poor experience while we worked through it). We’re working on these as a very high priority over the next couple of weeks.
Saving Stacks images
Saving any types of stacks to the SD card is still something we’re working through. You can share/save the image from the image preview, but we’re working through writing back to the SD card.
Firmware File Size
It's pretty large at the moment. Current firmware updates contain three things: 1) the OS/firmware, 2) the Arsenal software, and 3) the AI models. Up until now all three have been changing on most releases. We're almost to the point though where only the software will change for most releases. The software is only about 30MBs. In a future firmware update, we can move to building smaller firmware update files if a full update isn't needed.
Camera Settings Management
We've mentioned this before and are working on some improvements to 'reset' certain camera settings back to their previous status before Arsenal made changes.
