| 26 | +==== New features |
| 27 | + |
| 28 | +* Introduces a new feature for {elastic-defend} where Windows Image load events now include process protection status, making it easier to detect both legitimate and malicious PPL activity. |
| 29 | +* Allows you to examine Jamf data in the visual event analyzer ({kibana-pull}190965[#190965]). |

| 31 | +[discrete] |
| 32 | +[[enhancements-8.15.1]] |
| 33 | +==== Enhancements |
| 34 | + |
| 35 | +* Improves {elastic-defend} by reducing Malware Protection disk I/O and CPU usage when recently written files are subsequently executed. This update is for Windows endpoints only. |
| 36 | +* Makes several improvements to the detection and parsing of log samples uploaded to automatic import ({kibana-pull}190588[#190588], {kibana-pull}191502[#191502], {kibana-pull}190656[#190656], {kibana-pull}190046[#190046]). |
| 37 | +* Improves error handling for the Tines connector, and provides an option to use a webhook URL when connecting to the Tines API ({kibana-pull}191263[#191263]). |

| 40 | +[[bug-fixes-8.15.1]] |
| 41 | +==== Bug fixes |
| 42 | + |
| 43 | +* Fixes an {elastic-defend} bug that affected CPU usage for Windows process events where the same executable is repeatedly launched, for example, during compilation workloads. With this fix, CPU usage is improved. |
| 44 | +* Fixes an {elastic-defend} bug that sometimes caused malware scan response actions to crash when they attempted to scan an inaccessible directory. |
| 45 | +* Fixes an {elastic-defend} bug that sometimes caused {elastic-endpoint} to report an incorrect version if it used an independent {agent} release. |
| 46 | +* Fixes an {elastic-defend} bug where the `process.thread.Ext.call_stack_final_user_module.protection_provenance_path` field might be populated with a non-path value. This fix is for Windows endpoints only. |
| 47 | +* Fixes an {elastic-defend} bug that can lead to {elastic-endpoint} reporting `STATUS_ACCESS_DENIED` when attempting to open files for `GENERIC_READ`. {elastic-endpoint} almost always recovered from this issue, but with this fix, it succeeds on the first try. This fix is for Windows endpoints only. |
| 48 | +* Fixes an {elastic-defend} regression that was introduced in 8.14.0, where security events did not populate the `user.name` field. This fix is for Windows endpoints only. |
| 49 | +* Fixes an {elastic-defend} bug where {elastic-endpoint} sometimes missed file and network events on newer kernels that support eBPF. This only occurred if {elastic-endpoint} failed to enable eBPF probes and fell back to Kprobes. This fix is for Linux endpoints only. |
| 50 | +* Fixes a bug that caused errors if you used Azure OpenAI connector for streaming ({kibana-pull}191552[#191552]). |
| 51 | +* Fixes a bug that prevented duplicated prebuilt rules from inheriting **Required fields** and **Related integrations** field values ({kibana-pull}191065[#191065]). |
| 52 | +* Turns off the option to assign users to an alert if no assignees exist ({kibana-pull}190937[#190937]). |
| 53 | +* Fixes a bug that prevented Timeline template settings from being applied to new Timelines that were generated by a rule ({kibana-pull}190511[#190511]). |
| 54 | +* Fixes a bug that hid the option to select a connector for Elastic AI Assistant ({kibana-pull}189944[#189944]). |
| 55 | +* Removes the option to manually bulk-run multiple rules ({kibana-pull}190781[#190781]). |

| 113 | +==== Breaking changes |
| 114 | + |
| 115 | +* If you previously created any user-defined quick prompts for Elastic AI Assistant, they will no longer appear after you upgrade to 8.15. To resolve this, copy your existing quick prompts prior to upgrading, then add them again after upgrading. Additionally, in 8.15, quick prompts are shared by all users in your deployment, rather than saved at the user level ({kibana-pull}187040[#187040]). |

| 130 | +* Recalculates entity risk scores when asset criticality changes on an individual entity ({kibana-pull}182234[#182234]). |
| 131 | +* Adds an **Asset criticality** column to user and host data tables. If asset criticality levels are assigned to your users and hosts, this information appears in the **Asset criticality** column ({kibana-pull}186375[#186375], {kibana-pull}186456[#186456]). |
| 132 | +* Adds an API that allows you to perform paginated KQL searches through asset criticality records ({kibana-pull}186568[#186568]). |
