Hey folks!
Business as usual with fixes and catalog updates for this smaller Beta round. One notable change included with this update is that the Galaxy IC 1101 is being converted into a black hole host thanks to the diligent reporting by the community! We only have so many hands to check the massive list of objects in SE, so community feedback is always welcome!
As usual, any problems/inaccuracies with the beta can be reported via Support/Bug-Reports on the Discord or Troubleshooting & Bug Reports on the Steam Discussions.

Build 0.990.48.2055: Many Mini Moons
No issues detected in the Beta branch, so we're pushing the update to public! Here's the relevant news from the Beta post:
This month had a lot of extra catch-up between the usual exoplanet updates, more behind-the-scenes updates (as teased during our anniversary post in case you only read Steam notes), and the very exciting discovery of over a hundred more moons around our very own Saturn! Light reading and a list of the new moons can be found in this short NASA article.
The new moons are not easily findable with default settings. You will need to either use the Solar System Browser with Gas giant minor moons enabled (click the Gear in the left of the window), or use Find Object. Naming conventions are the same as the linked article, except with a space between the last letter/number (so S/2000 S3 becomes S/2000 S 3).
Changelog:
Updated small moons catalog with 128 new Saturn moons
Updated binary asteroids catalog
Updated the exoplanet catalogs with 17 new host stars and 28 new planets (listed below)
Added basic descriptions to the Info tab of the Wiki for 409 asteroids
Added LMC globular cluster NGC 1755
Improved distances and sizes of some open clusters
Disabled some phantom clusters
Updated size and orientation of M 101 and added proper name (Pinwheel)
Updated size of M 81
Updated orientation of IC 1296
Improved size and orientation of NGC 1211
Tweaked distance to IC 2163

The purpose of this beta is, as always, to catch any bugs that may pop up and give the community an opportunity to skim for errors we may have missed. The usual channels are always open on our Official Discord and the Troubleshooting and Bug Reports Discussion page here on Steam.
Additionally, we've seen some posts questioning catalog errors and/or how to report them. Simply put, they're inevitable. The catalogs are massive, and new entries get the bulk of our attention. Catalog errors and inaccuracies can be reported in the same channels as bugs, which are investigated and confirmed by the Support team, who pass it along for our astronomers to correct. If you can, include your source for the information that needs to be updated, as it makes it easier for Support to confirm and the fix to get in to the next patch!

Build 0.990.48.2050: Somewhere to Go
Nothing major cropped up over the weekend, so we're clearing the Beta build for public release!
This update brings fixes for some known issues with temperature ranges, along with a healthy serving of new exoplanets. Also new with this set of patch notes, we're including the full list of Catalog updates to answer the question every user has asked: "Where to?". Feedback welcome as we know it makes a longer read.
Dr. Megan, our resident brown dwarf enthusiast, highlights two entries from the new additions: Gaia-4 b and Gaia-5 b! "As their names suggest, these objects were discovered with the Gaia space observatory. Launched in 2013, Gaia was designed for astrometry: the precise measurement of the positions and distances of stars. Exoplanets and other stellar companions can leave distinct footprints in astrometric data; as these objects progress along their orbits, gravitational forces tug at the host star, and it wobbles around the system’s centre of mass. This results in the star following a corkscrew-like motion across the sky. When the host star is small and the orbiting body is large (like a massive planet or brown dwarf), these motions are larger, and easier to detect, as in the case of Gaia-4 b and Gaia-5 b. Gaia-4 b is a super-Jupiter, about 12 times the mass of Jupiter, orbiting an early-M or late-K dwarf star. Gaia-5 b is a brown dwarf with a mass of about 21 times the mass of Jupiter, orbiting a mid-M dwarf star. But just because massive planets orbiting smaller stars leave larger footprints, doesn’t mean they are very common! Smaller stars typically host smaller (and often more numerous!) exoplanets than larger stars. To find such a large planet and a brown dwarf-sized object orbiting these small stars is very unusual!"
Changelog:
Fixed a bug where Solar System Browser temperatures were not updating unless the planet was selected.
Improved the equator-to-pole temperature range when Tmin/Tmax are set in catalogs/editor.
Fixed a bug where temperatures were scaled inversely with distance to their parent star in binary systems with a catalog/editor temperature override.
Fixed acceleration for units mph, kn, and c being displayed as mph², kn², and c² instead of /sec.
Fixed a bug where the star browser filter "moon/exotic life biome: any" was not applying.
Enabled the Camera Velocity Vector Marker in Flight Simulator mode.

0.990.48.2050 Public Beta
Hey folks!
This Beta brings various fixes that will require testing before moving to public. Items we really want to ensure are working are highlighted in bold! We're also experimenting with a small format change to patch notes to better communicate new catalog additions, and would like feedback in this thread.
As usual, you can find the Beta branch by right-clicking SpaceEngine in your library, selecting properties, and Betas. Issues and inaccuracies should be reported in Troubleshooting and Bug Reports on Steam or #bug-reports on Discord!

Steam PC Café License Price Decrease
SpaceEngine has always held true as both a scientific tool and chill exploration sim. Users can pick it up and put it down as long as desired with no save points or time pressure, like a malleable atlas of the universe in a digital library.
So long as your place of learning or leisure has a computer network, it can have SpaceEngine through Steam PC Café! We've lowered the cost of a commercial license to just $9.99 a month and a single copy of the program.
How does this work?
This is meant for cybercafés, school computer labs, and other commercial shared computer arrangements
The base price to start a new license is $29.99 USD, like buying a copy of the game for one terminal in your network
Afterward, license upkeep is $9.99 USD a month per seat
SpaceEngine PRO is specifically for individuals like content creators and designers who want to use SE as part of their own product (like using screenshots for making HD posters to sell online).
Café licenses allow "Patrons of your venue [to] be able to log in with their personal Steam account, view the game licenses that you offer through their Steam library and have the option to 'check them out' temporarily while in your establishment." (Taken from https://partner.steamgames.com/doc/sitelicense/licensees/gettingstarted)
Build 0.990.48.2040: Warnings Optional
Hey folks!
No surprises from the beta, so moving straight to public with the latest update! We're bringing the usual catalog updates, as well as a new config parameter, ShowSeizureWarning, to enable/disable the bootup seizure warning. This can be found in your main-user.cfg file.
This round, we wanted to shine a little extra light on what "catalog updates" means. That is, one of our resident astronomers on the team manually adds any newly discovered objects into SE. This is just a sample of the 21 new objects added:
"This month I was excited to read about the NGTS-33 system, discovered and characterized using the Next-Generation Transit Survey (NGTS) robotic telescope array in Chile. The hot-Jupiter NGTS-33 b closely orbits its host star, a fast rotating, 7400 K, A-type star. Planets are not typically found orbiting massive stars like A-, B-, and O-type stars, making NGTS-33 b a unique discovery! It was also found to have a very low density and an inflated radius, about 15% larger than expected. But most excitingly, NGTS-33 b is a very young planet, only about 10-50 million years old. Detections of young planets are rare, and a large sample of them is needed for scientists to confirm theories of planet formation." -Dr. Megan
For readability and space, we don't typically list all the added objects (TOI-1301.01, TOI-1630.01, etc.). Browse official sites such as NASA's Exoplanet Archive or SIMBAD, and any entry older than a month or so (Dec 18th for this round) is more than likely already in-engine!
Changelog:
Updated the exoplanet and host star catalog, naming convention of Gliese objects
Added an option to the configuration files to show/disable the seizure warning called ShowSeizureWarning. See our previous Beta post for specific instructions to enable/disable!
