Anybody running streams
The default .htaccess was removed, so that one can now edit it to meet their personal needs without creating a git conflict in the future. It is only necessary if your webserver is apache, in which case you will need to use the template provided. We do attempt to copy the template back to .htaccess if it doesn't exist, but what I discovered is that this will only work if you load the baseurl, because the .htaccess file contains the rules to interpret URLS with paths. E.g. if your primary bookmark is to yoursite/stream, it will just whitescreen because the code to copy the file will never be reached. The code to reach this path is in the .htaccess file you don't have.
The next release is due in "a few days" give or take. When that happens, this requirement will move from the dev branch to the main branch and some sites will break. They will need to copy htaccess.dist to .htaccess and not everybody will remember this or know this, so please reach out to anybody having troubles with the upgrade.
The installation instructions have also been upgraded to mention this change.
