Deprecated and removed in version 9.4

This page lists features, computing platforms, and browsers for which Splunk Inc. has deprecated or removed support in this version of the Splunk platform.

What does "deprecated" mean?

Deprecated features, platforms, and browsers continue to work and Splunk supports them until support is removed. However, customers need to begin planning now for the future removal of support.

What does "removed" mean?

When Splunk removes support for a feature, platform, or browser it means that the feature, platform, or browser no longer works with the Splunk platform and customers must find an alternative.

Deprecated features in version 9.4

The following table summarizes the features that are deprecated. These features continue to be supported, but Splunk reminds customers that deprecated features might be removed in a future release.

Newly deprecated in this version	What do I need to know?	First deprecated
The Python 3.7 runtime environment	Splunk plans to remove the Python 3.7 runtime environment from Splunk Enterprise. Splunk urges customers to upgrade their apps to use Python 3.9 as soon as possible. Most likely Splunk will remove the Python 3.7 runtime in the next non-maintenance release of Splunk Enterprise.	Version 9.4.0
Version 3.0 of the Secure Sockets Layer (SSL) and versions 1.0 and 1.1 of the transport layer security (TLS) network encryption protocols	SSL version 3.0 and TLS versions 1.0 and 1.1 are deprecated and might be removed in a future release. To connect Splunk components and services securely going forward, specify TLS version 1.2 in configuration files for those components.	Version 9.4.0
Version 1 of the Splunk intra-node authentication protocol algorithm, as defined by the "v1" value for the signatureVersion setting in the server.conf configuration file	The "v1" value for the signatureVersion setting, which controls the message authentication code (MAC) that Splunk nodes use to authenticate with one another, has been deprecated. Its replacement value, "v2", was introduced in Splunk Enterprise version 7.2. Support for the "v1" value might be removed in a future release of Splunk Enterprise. For more information about configuring Splunk platform instances to use the updated MAC, see Configure secure communications between Splunk instances with updated cipher suite and message authentication code.	Version 9.4.0
Exporting dashboard PDFs, scheduling PDF delivery, and printing PDFs with Classic Simple XML dashboards.	Exporting dashboard PDFs, scheduling PDF delivery, and printing PDFs with Classic Simple XML dashboards is deprecated and will be removed in a future release.	Version 9.4.0
Hadoop Data Roll	Apache Hadoop Data Roll is deprecated and will be removed in a future release.	Version 9.4.0
Still deprecated in this version	What do I need to know?	First deprecated
The spawn_process parameter	Do not use the Splunk platform REST API spawn_process parameter. It is deprecated and will be removed in a future release.	Version 9.3.0
Splunk platform search execution methods	The phased_execution_mode setting is deprecated and should not be included in limits.conf configuration files. If the phased_execution_mode setting is specified, Splunk software displays a warning message instructing users to contact their administrator to delete the setting from their limits.conf file.	Version 9.2.0
The populate_lookup alert action	The legacy alert action, populate_lookup, is deprecated and will be disabled in a future release. Use the lookup alert action instead. You can still attach a lookup alert action to new saved searches even though the populate_lookup alert action is deprecated.	Version 9.2.0
The /services/search/commands REST API endpoint.	The undocumented /services/search/commands REST API endpoint is deprecated and will be removed in a future release. If you have been inadvertently using this endpoint, stop using it.	Version 9.2.0
Version 1 of Semantic Versioned endpoints for search	Select version 1.0 Rest API endpoints for search are deprecated. New Semantic Versioned Rest API endpoints for search are being introduced to improve platform contracts and resiliency to platform updates. Customers and app developers should update usage of these endpoints to the new API version, Search API version 2.0, and stop using Search API version 1 endpoints. See Semantic API versioning in the Splunk Enterprise REST API Reference Manual.	Version 9.0.1
Versions 3.0 and lower of the Splunk-To-Splunk (S2S) Protocol	S2S V3 is deprecated and will be removed in a future release. S2S Protocol V3 is automatically upgraded to V4 by default, and a warning message is generated.	Version 9.0.0
The createrss command	The createrss command is deprecated and disabled by default.	Version 9.0.0
The _reload action with the rest search command	Use of the _reload action with the rest command is deprecated. Do not use the _reload action with the rest command.	Version 9.0.0
The $SPLUNK_HOME/bin/srm (secure remove file) binary executable file	This binary executable, which removes files securely using a number of algorithms, was added in the version 6.0 release so that Splunk Enterprise could comply with Common Criteria requirements. Current Common Criteria guidelines preclude the need for the file, thus it has been deprecated and will likely be removed in a future release.	Version 8.2.0
Support of HTML dashboards	Support of HTML dashboards has been deprecated. Use Dashboard Studio to rebuild and configure dashboards.	Version 8.2.0
The msearch command	The msearch command is replaced with the mpreview command.	Version 8.1.0
The tscollect command	The tscollect command relies on time-series index (tsidx) files in namespaces that reside on individual search heads and are incompatible with search head clustering. This feature has been superseded by data models, which reside on the indexer and are more performant. Data models are accessible from any search head. See Accelerate data models in the Knowledge Manager Manual.	Version 7.3.0
literals.conf	Use of literals.conf has been deprecated. Use messages.conf to modify notifications that display in Splunk Web.	Version 7.2.2
