title: Splunk Firehose Nozzle for VMware Tanzu Release Notes
owner: Partners
---
### v1.2.4
**Release Date:** Dec 21st, 2021
Features:
* Fixed OAuth dependency issue, which caused auth failure when special characters were used in client secret.
* Updated web socket dependency to fix vulnerabilities.
* Fixed keep-alive connection implementation to reuse the connections (while sending events to HEC).
* Improved unit-testing code coverage.
* Improved debug mode to add more event details while printing to stdout.
* Added support for TAS 2.12.x
### v1.2.3
**Release Date:** Oct 18th, 2021
Features:
* Added option to forward envelope tags to splunk event [#278](https://github.com/cloudfoundry-community/splunk-firehose-nozzle/issues/278)
* Updated Splunk HEC retry counter default
* Updated Tile migration script (to fix config getting reset on nozzle upgrade)
* Updated logic to drop event when sink buffer is full to prevent passing back-pressure back to doppler, which was causing disconnects ([BUG] - Spunk nozzle transfers backpreassure upstream, resulting in client disconnects and doppler drops #285)
* Updated cache logic to fetch app info from BoltDB database if it is not found in in-memory cache or remote
* Upgraded go version to go1.17 and migrated from Glide to Go Modules
### v1.2.2
**Release Date:** May 7th, 2021
Features:
* Added support for NaN or Infinity value metrics
* Includes minor bug fixes
### v1.2.1
**Release Date:** August 5th, 2020
Features:
* Updated Tile to include migration step, required due to configuration (Add app info) field type change.
### v1.2.0
**Release Date:** July 27th, 2020
Features:
* Added consumer queue monitoring capabilities in the nozzle to help with back-pressure insights with events received vs sent count.
* Updated logging to include retry counter during HEC retries.
* Updated app metadata configuration:
* Add-app-info configuration now allows users to select interested app metadata fields (List includes: AppName, OrgName, OrgGuid, SpaceName, SpaceGuid).
* Removed cf_origin and cf_ignored_app fields from app metadata.
* Updated CI to include functional tests.
* Updated tile with recent stemcell i.e, 621.
### v1.1.2
**Release Date:** August 7th, 2019
Features:
* Updated authentication mechanism to use Client ID and Client secret. See [Configuration](installing.html#configure) for more information.
* Updated uaago library.
* Includes minor bug fixes.
### v1.1.1
**Release Date:** June 27th, 2019
Features:
* Upgrade cfclient, noaa, golang-net, and golang-sys libraries and dependencies.
* Allows configuration of keep alive duration `Firehose Keep Alive` for the firehose consumer from within the tile.
For more information, see [Configuration](installing.html#configure).
* Updated default value for `Org Space Cache Invalidate TTL` configuration parameter.
* Updated tile with latest CF-CLI version to address a high CVE.
### v1.1.0
**Release Date:** June 3rd, 2019
Features:
* Per application index routing: This feature enables applications developers/ users to send their application data to a specific index in Splunk. A `SPLUNK_INDEX` environment variable could be set within application manifest for the application which will then override the default SPLUNK_INDEX of the nozzle and send specific application data to specific index.
* Caching system refactoring for better performance. Adds `Org Space Cache Invalidate TTL` advance configuration parameter to the tile to update org and space cache directly.
* Exponential backoff for HTTP Event Collector retry mechanism.
* Removes `Splunk Version` configuration parameter from the tile as its no longer required. Please see [Limitations](index.html#limitations) for more information.
### v1.0.2
