 ### Added
 
-- Added a tracker component to the txmgr for tracking and gracefully handling abandoned transactions. Abandoned transactions occur when a fromAddress is removed from the keystore by a node operator. The tracker gives abandoned transactions a chance to be finalized on chain, or marks them as fatal_error if they are not finalized within a specified time to live (default 6hrs).
 - Added distributed tracing in the OpenTelemetry trace format to the node, currently focused at the LOOPP Plugin development effort. This includes a new set of `Tracing` TOML configurations. The default for collecting traces is off - you must explicitly enable traces and setup a valid OpenTelemetry collector. Refer to `.github/tracing/README.md` for more details.
 - Added a new, optional WebServer authentication option that supports LDAP as a user identity provider. This enables user login access and user roles to be managed and provisioned via a centralized remote server that supports the LDAP protocol, which can be helpful when running multiple nodes. See the documentation for more information and config setup instructions. There is a new `[WebServer].AuthenticationMethod` config option, when set to `ldap` requires the new `[WebServer.LDAP]` config section to be defined, see the reference `docs/core.toml`.

-- Fixed a bug that caused nodes without OCR or OCR2 enabled to fail config validation if `P2P.V2` was not explicitly disabled. With this fix, NOPs will not have to make changes to their config.
