WordPress 4.9.3 is a maintenance release and was originally scheduled to be available on January 30th. However, due to ongoing tickets and a short time frame to test the release candidate, it has been pushed back to February 5th.
WordPress 4.9.3 RC 1 is available for testing. This release removes JSHint from the code editors due to conflicts with the GPL License. If your code relies on JSHint from Core, developers encourage you to update it to use a copy of JSHint.
Other changes in 4.9.3 include, avoiding page scrolling when navigating the media modal, a handful of improvements to the customizer, and more. Please test WordPress 4.9.3 on a staging site and if you encounter any bugs, you can report them on the Alpha/Beta section of the support forums.
I have been getting a lot of memory dump files lately with 4.9.2 Googling the issue somehow brought me here. Is this perhaps a problem that is going to be fixed in the next update? or is it a hosting issue? I have never had this before since I started this site 4 years ago, and I have been with as many hosts in that time, now with Siteground GoGeek, 1 of the only 3 recommended on wordpress.org, so you would think they are WordPress specialists, which I think they are. They are also very generous with their resource allocations, WP Max memory limit something like 768MB, and 512MB in wp-config. Their new shared servers are monsters. Funny thing is the site is flying like there is no tomorrow, so I guess I’m just stumped as to how these files came to be, I like to keep it all neat and tidy, but they keep coming back, each one 20MB. I have not added any new plugins since I moved to SG a month ago.
