rollbar-php v0.9.2 released

Version 0.9.2 of rollbar-php has been released, offering a crucial fix for a problem that previously affected high-volume environments using rollbar-php with rollbar-agent. The issue involved relay log filename collisions, which have now been addressed by incorporating both the process ID (PID) and the current time in microseconds into the filenames. This update is available for download on Packagist and GitHub, and the contribution was made possible through a pull request by Ryan Fink.
