|
|
|
|
2026-04-08 13:45:59 -07:00
|
|
|
- **Context Management:** Introduced a Context Compression Service to optimize
|
|
|
|
|
context window usage and landed a background memory service for skill
|
|
|
|
|
extraction.
|
|
|
|
|
- **Enhanced Security:** Implemented context-aware persistent policy approvals
|
|
|
|
|
for smarter tool permissions and enabled `web_fetch` in plan mode with user
|
|
|
|
|
confirmation.
|
|
|
|
|
- **Workflow Monitoring:** Added background process monitoring and inspection
|
|
|
|
|
tools for better visibility into long-running tasks.
|
|
|
|
|
- **UI/UX Refinements:** Enhanced the tool confirmation UI, selection layout,
|
|
|
|
|
and added support for selective topic expansion and click-to-expand.
|
|
|
|
|
- **Core Stability:** Improved sandbox reliability on Linux and Windows,
|
|
|
|
|
resolved shebang compatibility issues, and fixed various crashes in the CLI
|
|
|
|
|
and core services.
