ServiceBond Release Notes See what's new in all the integration available to facilitate automated Service Provider to Customer interactions! Release Highlights   Optimize performance with ServiceNow GlideEncrypter deprecation Support different encryption options  to optimize performance from end to end (ServiceNow application, DataSync Agent and meshlets) with the GlideEncrypter deprecation in the ServiceNow platform.   Includes the newest third party libraries The DataSync Agent and meshlets now come with the latest versions of the Spring libraries and AWS S3 libraries along with the latest versions of the JDBC drivers for Microsoft SQL Server, Oracle and Snowflake to improve security and performance.   Support for the latest versions of ServiceNow The Perspectium ServiceNow application supports up to the latest version of ServiceNow ( Yokohama ) so you can upgrade to the latest ServiceNow version in your instance and be confident the Perspectium application will continue to function.    Support for the latest Java versions The DataSync Agent and meshlets support the latest stable Java up to Java 23 to ensure you can use the newest Java with its bug and security fixes and performance improvements.  Upgrading to Lithium General Upgrade Considerations With the changes in the Perspectium application related to ServiceNow's  deprecation of the GlideEncrypter API , it is recommended you upgrade all your Perspectium applications to the Lithium version in order to leverage the new  Encrypt on Send encryption option and encrypt data using AES encryption method .   For considerations related to the deprecation of the GlideEncrypter API (such as installing the Perspectium application on a clean instance of Yokohama , see our documentation on here . It is suggested to not  use  TripleDES  as the encryption method going forward as there will be performance issues since a third-party JavaScript library is now used for TripleDES encryption and is substantially slower than the  GlideEncrypter  API. This is due to the library being executed externally at the client platform level whereas ServiceNow APIs are ran at a lower platform level with more direct access to the data. As well,  Triple DES  as a security encryption standard is no longer a recommended option per  NIST-800-131A  (and the reason ServiceNow is removing GlideEncrypter).  Perspectium Core ServiceNow Application See the General Upgrade Considerations section above about upgrading all your Perspectium applications to Lithium . It is recommended to do incremental upgrades so you're upgrading from a more recent major version to  Lithium.  Ideally you are upgrading from  Krypton to  Lithium so if you are on an older version, we recommend you first upgrade to  Krypton (or at the very least  Iodine ) before upgrading to  Lithium. Upgrading from a really old version such as  Fluorine can lead to issues due to the many changes in the Perspectium application in between major versions.  Related to the general upgrade consideration about not using  TripleDES , after doing the upgrade to  Lithium , we suggest you update your dynamic shares and clone your bulk shares to use an AES  encryption method such as AES-128 or AES-256 .   NOTE : If you using AES-256, you will have to update your encryption key to be 32+ characters in your shared queue or default  DataSync Settings . For those with installs of  Krypton 8.4.0 or older , you will need to upgrade your Perspectium application to  Lithium  before the GlideEncrypter API is completely removed in the Zurich release in Q4 2025 since we will need to use the GlideEncrypter API to migrate your properties over. The GlideEncrypter API is needed in order to access your current encryption key and MBS credentials from ServiceNow's backend to save back into the system in the password2 field types. Otherwise, if you do not upgrade before then, you will have to manually re-enter your MBS credentials and default encryption keys in the  Perspectium Properties  page (information will be provided in Q4 2025 on how to enter it manually). If you request a new instance of ServiceNow with Yokohama, the GlideEncrypter API will not be available. You will only be able to install  Lithium 9.2.0 or newer  as older versions of the Perspectium application use GlideEncrypter. This only applies to new instances as instances that are upgraded to Yokohama from a previous version (such as Xanadu) will still have the GlideEncrypter API until the complete removal of it with the Zurich release of ServiceNow in Q4 2025. If you install an older version of Perspectium on a new instance with Yokohama, you will get the error  java.lang.SecurityException: Unsupported call to GlideEncrypter. Details: GlideEncrypter is deprecated and now returns null, please refer KB1320986 for alternatives; Reason: TripleDES deprecation; Category: Security  when running the application. If you were previously using the Perspectium Core application with your properties stored in the  sys_properties  table, you will need to re-enter your secure properties manually after upgrading. The sys_properties records cannot be accessed to move over.    NOTE : This is a non-standard approach and not enabled by default (you would have worked directly with the Perspectium team to enable this). Contact  support@perspectium.com  for more information. Follow these steps to upgrade the Perspectium Core ServiceNow application to Lithium. DataSync Agent See the General Upgrade Considerations section above about upgrading all your Perspectium applications to Lithium . Related to the general upgrade consideration about not using  TripleDES , after doing the upgrade to  Lithium and updating the Perspectium Core ServiceNow application to an AES  encryption method , you will only have to update the Agent's agent.xml configuration file if you change the encryption key (see the Perspectium Core ServiceNow Application section above for more details).  If you are leveraging the Encrypt on Send option as detailed in Encrypting Content Sent to MBS Approach , you will only need to upgrade to a Lithium version of the DataSync Agent. You do not need to make any other configuration changes in the Agent. Backup your current DataSync Agent's installation (the entire directory containing the installed DataSync Agent and its configurations) prior to doing an upgrade. Follow these steps to upgrade the DataSync Agent to Lithium . Meshlets See the General Upgrade Considerations section above about upgrading all your Perspectium applications to Lithium . Related to the general upgrade consideration about not using TripleDES , after doing the upgrade to  Lithium and updating the Perspectium Core ServiceNow application to an AES  encryption method , you will only have to update the meshlet's application.yml configuration file if you change the encryption key (see the Perspectium Core ServiceNow Application section above for more details).  If you are leveraging the Encrypt on Send option as detailed in Encrypting Content Sent to MBS Approach , you will only need to upgrade to a Lithium version of the meshlet. You do not need to make any other configuration changes in the meshlet. Backup your meshlet's installation (the entire directory containing the installed meshlet and its configurations) prior to doing an upgrade. Follow these  steps to upgrade a meshlet to Lithium . Release Names and Packaging The releases name are in the format of .. . The contents of a release package are based on the name and are as follows: Format Description Major Version of the software that contains significant new features, enhancements, and/or improvements in the user interface (UI) or user experience (UX).  Perspectium's release name follows the chemical elements (e.g. Krypton) and are released alphabetically. For example, Lithium 9.0.0 is the major release following Krypton 8.0.0. Minor/Patch A set of changes that contains updates, bug fixes, and/or improvements on the product. This release version can be installed by itself without a major release.  (e.g. Lithium 9.1.0 )  Hotfix A set of changes that addresses a specific issue. This release version cannot be installed by itself, it will need to be uploaded on top of a major or patch release. Hotfixes are not cumulative so hotfix 2 will not contain fixes in hotfix 1. Hotfixes require that you click Finish Install after you’ve previewed and committed the update set. (e.g. Lithium 9.0.1 also known as Lithium Hotfix 1)  Release Compatibility Perspectium tests  n-2 compatibility with each release e.g. the previous two major releases of the Agent prior to this release has been tested with the latest version of ServiceNow.
