Using snmpGetAllVariableBindings() method, if a request was sent to a table (present at the end of the MIB file) in which the rows are not implemented, the SnmpTarget's getErrorString() method returned a 'No Error' message instead of 'End of Mib file'. Also, the GETNEXT requests were sent again even after the occurrence of the error. These issues have been fixed.
Using snmpGetBulkVariableBindings() method if a request was sent to a table (present at the end of the MIB file) in which rows are not implemented, the SnmpTarget's getErrorString() method returned a 'No Error' message instead of 'End of Mib file'. Also, the GETBULK request was sent again even after the occurrence of the error. These issues have been fixed.

Previously, we were handling the SMIv1 INTEGER with the range - 231 to 231 - 1. Now it is made to handle the range - 263 to 263- 1.
Serialization of SNMPv3 PDU was not possible before. This has been fixed.
The acknowledgement packets always have SNMP version set to v1 even when the incoming notifications are SNMPv2c or SNMPv3 informs. This issue has been fixed.
The discovery report is not received when an SNMPv3 inform is sent as a discovery request with an username other than "initial" and zero length String. This issue has been fixed.
When agent A sends an inform and agent B sends a trap simultaneously, then the inform acknowledgement was sent to B instead of A. This issue has been fixed.
If an IP address is sent as one of the varbinds with the Character Encoding set other than the default one, then "Trying to allocate VERY BIG PDU" error is thrown. This issue has been fixed.

When the MIB is loaded from the serialized MIB file and when the method getMibNode(Vector) of MibModule is called with numbered OID String as the argument, NullPointerException is thrown. This has been fixed.
While loading the MIBs using the method loadMibModule(Applet, URL), the primary modules are searched in the specified location. Though the MIB path is specified and the MIB is present in the specified location, while loading the imported modules, the MIB is being searched in some other location and at last it finds the MIB in the specified location resulting in performance problems. This issue has been fixed.
When getMibNode() is called, the first occurrence of the node is returned. Suppose if a module imports a node, sometimes this method returns the node corresponding to the imported module. But the node corresponding to the imported module does not contain all information about the node. Therefore the node instance corresponding to the parent module alone is returned.
If the syntax of the node is a Standard TC, the (syntax instanceof MibTC) was returning false. This issue has been fixed.
If the primary module is present in one directory and the imported module is present in another directory and if the filename and the module name of the imported module are different, FileNotFoundException is thrown, when we try to load the primary module even if setMibPath() of MibOperations class is called with these two directories as argument. This issue has been fixed.
For some MIBs (for example P-BRIDGE-MIB extracted from RFC2674), the method getRootNode() does not return the correct root resulting in incomplete MIB tree. This issue has been fixed.
When the method setMibPath() in MibOperations is called with some directories as argument and when we try to load a MIB which is located in some other directory not specified in the setMibPath (by giving the full path of the MIB file) the FileNotFoundException is thrown. This issue has been fixed.
If an OID which is not present in a MibModule is given as argument, the method getMibNode() of MibModule class returns the available node present in this module which matches a part of the OID given, instead of returning null. This issue has been fixed.
Since the method getMibNode() of MibModule fails, the method translateToNames also fails, as it uses the getMibNode() internally. This has been fixed.
The OutOfMemory Exception was thrown when we try to load a MIB which is in not in same case as the file that is present in the directory. This issue is reproducible only in Windows. This has been fixed.
The performance of the method getMibNode(SnmpOID) in MibOperations has been improved.
In the method createVariableBinding(varName, indexes, value) of MibOperations, if the first character of the argument varName is an alphabet and if second character is a number, then IllegalArgumentException was thrown. This issue has been fixed.

While adding augments/external indices for a table, NullPointerException is thrown. This issue has been fixed.
In a Multithreading environment, the method getNearestNode(SnmpOID) in the class MibOperations sometimes doesn't returns the nearest node, but some other node much higher in the tree. This issue has been fixed.
If the syntax of a node is OBJECT IDENTIFIER and if its DEFVAL clause contains the value 'zeroDotZero', then the MIB tree is incomplete. This issue has been fixed.
The MIB loading performance has been improved especially in case of MIB files which is larger in size.
Loading a MIB file with a imported module and the imported module is in a MIB as a second module(Multi Modular MIB). Also the imported mib modules name and the name of the file(MIB) in which it is present are different.
Fix for DecodeInsanceString method where the last Index is of type OBJECT IDENTIFIER and is Implied. Previously Implied is not properly considered.
The method snmpGet in SnmpTarget returns incosistent result in threaded environment. The method for any oid sometimes returns string formated oid (e.g .iso.org. and numeric oid the other time.The fix is done by synchronizing the method getNearestNode in MibOperations.
Issue in loading the .ser file. Previously .ser file gets loaded only when the corresponding MIB is present in that location. Now the fix has been done to load .ser file without the necessary mib file.
In the method getRange(String s), counter to increase the BITS value is corrected, instead of loop counter.
Issue in loading the mib with .MIB extention is fixed.
Fix for loading the mib where the root mib and its imported mibs are from space seperated directory from MibBrowserUI.

When init_v3_parameters() of USMUtils is called for an AUTH_PRIV user with the boolean validateUser set to true, a request is sent to check the priv password.
Previously in MibBrowser, while adding NO_AUTH_NO_PRIV users in the USM table, the entry is added even if the user does not exist. It has now been made to check if the user exists. Also, while adding AUTH_PRIV users, the priv password is checked.
The create_v3_tables() of SnmpServer is now made to set the v3-specific error codes.
A new constructor and a method has been added in the SnmpInt class to accept and return a "long" value. This has support for 64-bit integer values for INTEGER data-type. This is mainly for SNMPv1, because SNMPv2c/SNMPv3 has only 32-bit integer values.
