Introduce `ui.scrollback_lines` (default 2000) to cap the number of chat lines kept in memory, with `0` disabling trimming. Implement automatic trimming of older lines, maintain a scroll offset, and show a “↓ New messages (press G)” badge when new messages arrive off‑screen. Update core UI settings, TUI rendering, chat app state, migrations, documentation, and changelog to reflect the new feature.
Migration Notes
Owlen is still in alpha, so configuration and storage formats may change between releases. This directory collects short guides that explain how to update a local environment when breaking changes land.
Schema 1.2.0 (November 2025)
config.toml now records schema_version = "1.2.0" and introduces the optional ui.input_max_rows and ui.scrollback_lines settings. The new keys default to 5 and 2000 respectively, so no manual edits are required unless you want a taller input panel or a different scrollback cap. Existing files are updated automatically on load/save.
Schema 1.1.0 (October 2025)
Owlen config.toml files now carry a schema_version. On startup the loader upgrades any existing file and warns when deprecated keys are present. No manual changes are required, but if you track the file in version control you may notice schema_version = "1.1.0" added near the top.
If you previously set agent.max_tool_calls, replace it with agent.max_iterations. The former is now ignored.
