Hi Aditya,

You can use FeedItem salesforce standard object to track the feed item changes. Below is sample code that I did one of my project.

/* Apex Class */ 
public with sharing class ChatterHistoryBrowserController {

    public List<OpportunityFeed>feedHistory {get; set;}
    public String month {get; set;}
    public String year {get; set;}
    
    public ChatterHistoryBrowserController(ApexPages.StandardController con) {
        feedHistory = new List<OpportunityFeed>();  
        feedHistory = [SELECT Id, Type,CreatedById, CreatedBy.FirstName, 
        CreatedBy.LastName, CreatedDate,ParentId, Parent.Name, (SELECT Id, FieldName, OldValue, NewValue FROM 
        FeedTrackedChanges ORDER BY Id DESC), 
        (SELECT Id, CommentBody, CreatedDate,CreatedById, CreatedBy.FirstName, 
        CreatedBy.LastName FROM FeedComments ORDER BY CreatedDate ASC, ID DESC LIMIT 10) 
        FROM OpportunityFeed ORDER BY CreatedDate DESC, ID DESC LIMIT 20];
    }
    
    
 
}
/* --------- VF Page --------------*/ 
<apex:page standardController="Opportunity" extensions="ChatterHistoryBrowserController">
    <div class="pageBlockBox">
    <apex:pageBlock title="Chatter Posts from the Past" id="resultBlock">
        <apex:repeat value="{!feedHistory}" var="f">
               <!-- display the posts -->
               
               <div id="chatterPost">


               <apex:Repeat value="{!f.FeedTrackedChanges}" var="cf">
                          
                        <apex:outputLabel id="comment-repeat"> 
                            
                          changed  {!SUBSTITUTE(cf.FieldName, "Opportunity.", "")} &nbsp; to {!cf.NewValue}
                        </apex:outputLabel>
                        <apex:variable value="{!SUBSTITUTE(cf.FieldName, "Opportunity.", "")}" var="newVar" />
                        <apex:outputlabel >

                        </apex:outputlabel>
                        
               </apex:Repeat>

               </apex:outputText>
           
               </div>

            border:solid 2px #1797C0;
        }
        #leftFloat {
            float:left;
        }
        .chatterLink {
            color:#1797C0 !important;
            font-weight:bold;
            text-decoration:none;
        }
        .pageBlockBox {
            width:600px;
        }
        .dateText {
            color:#6F6F6F;
            font-size:11px;
        }
    </style>
</apex:page>
Also, refer below link for FeedItem Object.

Let me know if this works :)
Thanks!
