KeyServer 7.5.0.8 can save corrupt dashboards, causing them to revert to the Default dashboard (2019-02-23)
Depending on the exact configuration of the dashboard being saved, the server might decode the dashboard incorrectly and truncate the dashboard file. The next time the dashboard is loaded in a browser, the dashboard data will not parse correctly, wihch causes the Default dashboard to be loaded instead. To avoid this issue, upgrade to KeyServer version 7.5.0.9 or higher.
KeyAccess 7.5.0.0 through 7.5.0.7 on macOS can exclude many programs from the audit (2019-01-31)
In certain cases when there are soft links directly to an app, other apps within the same directory will not be reported as part of a full audit. Upgrade KeyAccess on macOS clients to version 7.5.0.8 or higher to collect complete audit information.
KeyAccess earlier than 7.5.0.8 can generate extra Computer records following a change to ID types (2019-01-31)
When KeyAccess performs a software audit at a time when no user is logged into the OS, it can fail to use the Computer ID that has previously been used for that computer. This happens especially in cases where a change has been made to the Computer ID Types. This can result in duplicate Computer entries. Upgrade KeyAccess to version 7.5.0.8 or higher to ensure that the client uses the same ID for all audits on a given computer.
KeyAccess 7.5.0.7 on macOS reports keyed software as unkeyed in software audits (2019-01-31)
KeyAccess 7.5.0.7 on Mac reported all installed software is unkeyed. This is fixed by updating to 7.5.0.8.
KeyAccess 7.5 running on macOS 10.14 “Mojave” will generate a warning message the first time a browser is launched (2018-11-15)
Security and privacy changes in macOS X 10.14 include a sandboxing feature that prompts the user to allow applications to commumicate with each other. To track URLs, KeyAccess uses this gated IPC mechanism when querying browsers for information on which URLs have been loaded. The first time KeyAccess queries a given browser, the OS will display this prompt. Once the user allows or disallows the communication between KeyAccess and the browser, the OS will not prompt again. The setting can be changed in the Security & Privacy system preference panel (under the Privacy tab select Automation).
KeyServer versions 7.5.0.3 and 7.5.0.4 installed on Windows as a 32-bit process can give incorrect report results and have other subtle problems (2018-10-22)
Running the 32-bit Windows version of KeyServer 7.5.0.3 or 7.5.0.4 can result in reports that show "Policy not found" and other incorrect or inaccurate information. The raw user data is not affected, so there is no loss of accurate data. To avoid this issue, upgrade to KeyServer version 7.5.0.5 or higher. Most modern computers are capable of running 64-bit OSs, so we recommend using the 64-bit KeyServer when possible. There is no need to convert data when upgrading from 32-bit to 64-bit executables; the same data can be used on all platforms regardless of OS type, “bitness”, or version.
KeyAccess versions prior to 7.5.0.5 might exhibit excessive CPU usage on Windows (2018-10-22)
Windows KeyAccess versions older than 7.5.0.5, in rare cases, will show high CPU usage after running without issue for some length of time. The chance of this happening is low, but is more likely on multi-user systems such as Windows Terminal Server when many sessions are connected, depending on usage patterns. To avoid this issue, especially important when KeyAccess is installed on WTS with heavy use, upgrade to KeyAccess version 7.5.0.5 or higher.
KeyAccess versions 7.5.0.0 and 7.5.0.1 cause a compatibility problem with Microsoft Access and Internet Explorer (2018-08-08)
With KeyAccess version 7.5.0.0 or 7.5.0.1 installed, the first launch of either Microsoft Access or Internet Explorer will fail silently. Subsequent launches of the program will succeed. To avoid this compatibility issue, upgrade to KeyAccess version 7.5.0.3 or higher.
KeyServer versions 7.5.0.0 and 7.5.0.1 can crash under normal operation (2018-07-26)
We strongly recommend that you upgrade to version 7.5.0.2 or higher if you are running one of these earlier versions of KeyServer, even if you have not experienced any crashes yet.
KeyServer installers for versions 7.5.0.0 and 7.5.0.1 might fail to upgrade maps from earlier versions (2018-07-26)
If you upgraded from 7.x to 7.5.0.0 or 7.5.0.1, and had set up any Availability Maps in 7.4, your maps might not have been transfered to the upgraded server. Contact Sassafras Software for help moving the necessary files into place on the new server. Part of the process will include upgrading your KeyServer to version 7.5.0.2.
Cautions when upgrading from an earlier major version – i.e., 7.4 or earlier (2018-07-05)
Read the Major Upgrade documentation!
K2 7.5 requires a new license certificate (server.lic) and new KeyConfigure. Before upgrading an older KeyServer version (6.2, 7.0, 7.1, 7.2, 7.3, 7.4, etc) you must receive a new license certificate configured for 7.5 support -- a 7.4 or earlier certificate will not enable version 7.5.
The major version of KeyConfigure version and KeyServer version must match (e.g., first two digits must match). KeyConfigure 7.4 won't connect to KeyServer 7.5, KeyConfigure 7.5 won't connect to KeyServer 7.4.
Any KeyShadow installs must be discarded whenever the KeyServer process is upgraded. The KeyShadows must be recreated with a version 7.5 shadow certificate created by the version 7.5 KeyConfigure.
In cases where the Windows KeyServer is running in a Service Account, the Service Account must have a valid password that is reflected in properties of the KeyServer Service in the Service control panel. Furthermore, the Account must have full permissions on the KeyServer Data Folder in order for KeyServer and KeyReporter to properly run. Therefore, it is important to double-check permissions if your KeyServer is configured to run as anything other than the local service account.
On Windows, if your 7.4 (or older) KeyServer data is stored at a non-default location (for example on a non-system drive), the 7.5 Server installer will move the converted data to the default location in C:\Program Files\Sassafras K2\Server unless you select the “KeyServer Data Folder” item within the installer's “Sassafras K2 KeyServer Setup” dialog and browse to the existing Data Folder's Drive/Path during the install. This is necessary because the data folder is now a distinct entry in the installer. Choosing this option once will allow the data folder to remain at that location for any subsequent 7.5.x upgrades.
If your KeyServer is configured to Export databases, you should adjust the external tables as described in the New Fields section of the Tables documentation.
Minimum supported version of Mac OS X is 10.8 (2018-07-05)
K2 7.5 has several operational and UI improvements that require Mac OS X 10.8 and higher. Previous versions of K2 support Mac OS X 10.6 and higher, so if you have client computers with OS X 10.6 or 10.7, you should use KeyAccess 7.4.2 on those systems. The older client versions are compatible with the 7.5 server, although the newer functionality will obviously be missing for those clients.
