Table 1. Engine and Architecture
Overview	Reference

Introducing the `res.ic.server.port` resource for the GAS server port. It replaces the resources `res.ic.base.port` and `res.ic.port.offset`, which are now desupported. The default GAS server port number is still 6394.	See New GAS server port resource: res.ic.server.port
Introducing the `TCP_SERVER_PORT` element to configure the GAS server port. It replaces the function of the `TCP_BASE_PORT` and `TCP_BASE_OFFSET` elements, which are now desupported.	See TCP_SERVER_PORT
On Unix-like platforms you can use systemd to manage the GAS dispatchers. You can perform various management tasks, such as starting and stopping the dispatcher, using `systemctl` commands. Templates for configuring GAS systemd are provided in FGLASDIR/systemd/ Warning: The systemd feature is available on Linux® only.	See Systemd service template
There are changes to the log categories as defined in `CATEGORIES_FILTER`. The log categories are simplified down to these categories: `ERROR`, `WARNING`, `INFO`, and `DEBUG`.	See CATEGORIES_FILTER
There are verbs for `service` and `application` in the gasadmin tool. The gasadmin service command has functions for managing web services, such as validating services, and enabling and disabling services. The gasadmin application has functions for managing applications, such as enabling and disabling applications.	See gasadmin tool.
The gasadmin list-sessions verb is added. This provides options for listing sessions, including outputting the list in JSON format.	See gasadmin tool
The `SEND_VERSION` element is added to allow you to configure the header for GAS version. It is set to `FALSE` by default.	See SEND_VERSION
The resource `res.http.send.version` is added to apply internally the setting for sending the GAS version. It is set to `FALSE` by default.	See SEND_VERSION
The `--keep-alive-timeout` option is added in the standalone dispatcher, httpdispatch. Once an HTTP request has been processed, the timeout specifies how long the dispatcher will wait for a subsequent HTTP request before closing the connection with the client. Default is 15 seconds.	See httpdispatch
Starting at 5.00.02
The gasadmin gar --list-archives command allows an argument with options for listing details of deployed archives.	See: Argument added to gasadmin gar --list-archives command gasadmin
The gasadmin gar --clean-archives command allows an argument with options for cleaning (removing) specified archives.	See: Argument added to gasadmin gar --clean-archives command gasadmin
The gasadmin session --list-session-ids option is added to list the identifiers of the sessions running in the GAS.	See New option to list session ids in the gasadmin session command gasadmin
The gasadmin session --count-sessions option is added to count the active sessions running in the GAS.	See New option to count sessions in the gasadmin session command gasadmin

Table 2. Web services and the GAS
Overview	Reference
The GAS now supports HTTP/3. If Apache, nginx, or IIS web servers are configured to support HTTP/3, the GAS can support the HTTP/3 protocol.	No additional reference.
There are improvements for the management of reverse proxy server, load balancer, and integrated cloud solutions. The GAS supports use of X-Forwarded header `X-Forwarded-Prefix`. X-Forwarded-Prefix should contain the PathBase (/`path`/`base`) of the URI.	See: Configuring load balancer for X-Forwarded headers Apache: configure for reverse proxy IIS: configure for reverse proxy
Support for HTTPS is added in the standalone dispatcher httpdispatch. It can run either in HTTP or in HTTPS. In HTTPS mode the dispatcher is started with the `--cert-file` and `--cert-key` options to specify SSL certificates.	See httpdispatch

Table 3. Single Sign-On (SSO) and delegation
Overview	Reference
Single Sign-on topics are no longer included in the Genero Application Server User Guide. SSO is now documented in a separate manual.	See Single Sign-On User Guide.
