# 8.30 Maintenance Release 3 Enhancements or bugs resolved in this version are as follows. Important Notes: Command Centre version numbers comprise a major build version and a minor build version, (e.g. for version vEL8.30.1359, 8.30 is the major build and 1359 is the minor build). Server and workstation major builds must always match, however the minor build on the workstation can be equal to or lower than the server minor build. This feature is intended to ease the effort required for upgrades by allowing a server only maintenance upgrade. Some maintenance fixes are workstation based and may require a workstation upgrade to resolve an issue. Sites that are using ClickOnce installation of Command Centre and Configuration Client will automatically upgrade the clients. Example: For this Maintenance Release, sites that are already running Full Release version of v8.30 Command Centre Server, can choose to leave their MSI workstations running Full Release version vEL8.30.1057 if they are not affected by the bugs fixed in “Workstation”. Please refer to the “Fixed In” column in the below table for full details. | Category | Fixed In | Description | Tech Ref | | --------------------- | ----------- | ----------------------------------------------------------------------------------------------------------------------------------- | -------- | | Action Plan | Controller | Command Centre items continue to follow default Action Plan, ignoring assigned custom Action Plan | 83652 | | Cardholder Viewer | Workstation | Improvements to Cardholder search | 82577 | | Clients | Workstation | Workstations failed to logon with ‘The configured server is not trusted by this client’ | 83601 | | Command Centre | Server | ‘Lock request time out period exceed’ error when saving Cardholder | 84584 | | Command Centre | Server | Duplicate instances of Access Group memberships with same from/until time are sent to the Controller | 82858 | | Command Centre | Server | Exception created due to incomplete card records | 82943 | | Command Centre | Server | Memory leak that impacts monitored items and server performance | 81925 | | Command Centre | Workstation | Command Centre Client crashing due to memory exceptions caused by Automation peers | 82699 | | Command Centre | Workstation | Server creates exception when there are disconnects in DCOM tunnelling | 82272 | | Command Centre Client | Server | Cardholder history not updating on cardholder viewer, due to enforcement of CSN length | 83881 | | Command Centre Client | Workstation | Command Centre Client crashes due to ‘system out of memory exception’ | 85939 | | Command Centre Client | Workstation | Controlled Entry Viewer customisation exception when closing a viewer | 82872 | | Command Centre Client | Workstation | Failed logons can result in TCP connections being left behind | 85191 | | Configuration Client | Workstation | Add an additional unlock button to Windows logon Operator configuration | 82843 | | Controller | Server | Controller logging improvements | 85679 | | EDI | Server | EDI not running after upgrading due to custom defined stored procedure | 83026 | | Elevator | Server | Exception created when using OPC with elevator systems | 82019 | | Macros | Server | Exception when alarms are processed using Macro while system alarms are visible in the viewer | 82870 | | Morpho | Server | Fingerprint is not updated on the Morpho reader | 82719 | | Morpho | Server | Prevent exception if biometric communicator could not be created/launched | 85015 | | Multi-Server | Server | Remote Server exception caused by scheduling Macro | 84472 | | Notifications | Server | Enabling Card expiry notification on Card Types produces erroneous notifications | 83325 | | Otis Compass | Server | Mobile Credential does not work with default floor | 83854 | | PDF | Server | Command Centre performance degrade when PDF is configured with dates earlier than 01/01/1900 | 85273 | | PDF | Server | PDF performance improvements | 83669 | | Performance | Server | Controller Service optimisations | 84038 | | Performance | Server | Mobile Access readers incurring significant performance reduction | 84959 | | | | | 85212 | | Performance | Server | Rest API memory leak | 85604 | | Printing | Workstation | Exception created if print preview window is closed while printing | 82446 | | PSTN Dialler | Controller | Support for new PSTSN Dialler component | 83210 | | Site Plan | Workstation | Configuration Client Site Plan Icons may flicker after upgrade | 82191 | | SNMP | Server | Services fail to start after upgrade with large SNMP config | 82491 | | System Upgrade | Server | Command Centre fails to upgrade due to duplicate items in the Bulk change | 82367 | | T2x Readers | Controller | CAC G\&D cards are not detected at T21 contact card reader | 78114 | | Test Server | Server | Sites can load production server database on test server based on original serial number without affecting their Mobile Credentials | 84330 | | | | | | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
