The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from the OVM (Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) for the e Verification Language developed by Verisity Design in 2001.

Hey!!
Here is your answer:-
UVM 1.0 was released on 28 Feb 2011 with the explicit endorsement of all the major simulator vendors. Since that time UVM has become the only show in town when it comes to standardized SystemVerilog verification methodologies. UVM has undergone a series of minor releases, which have fixed bugs and introduced new features.
❇️ The source code for the original 1.0 release, known as the UVM Base Class Library (BCL), evolved from the UVM Early Adopter release, which in turn was based on OVM version 2.1.1. The most obvious difference between OVM and UVM-EA was that all occurrence of the prefix "ovm_" were quite literally replaced with "uvm_", "OVM_" by "UVM_", "tlm_" by "uvm_tlm_", and so forth. The UVM-EA kit included a script to convert existing OVM source code. UVM-EA added a few new features on top of OVM 2.1.1, which itself added a few new features to OVM 2.0. The most noticeable additions in the 1.0 release were:
An end-of-test objection mechanism to ease the task of cleaning up at the end of a verification run
A callback mechanism that provides an alternative to the factory for customizing behavior
A report catcher to ease the task of customized report handling
A heartbeat mechanisms to monitor the liveness of verification components.
