New features

Added search across local conversation history, including case-insensitive content matches with result previews. (#23519, #23921)
Made --profile the primary profile selector across CLI, TUI permissions, and sandbox flows, with legacy profile configs rejected through migration guidance. (#23708, #23883, #23890, #24051, #24055, #24059, #24067, #24110)
Improved MCP setup with per-server environment targeting and OAuth options for streamable HTTP servers. (#23583, #24120)
Made connector tool schemas more reliable by preserving local $ref/$defs structures and compacting oversized schemas before exposure. (#23357, #23904)
Let read-only MCP tools run concurrently when they advertise readOnlyHint. (#23750)
Added richer extension and hook context, including conversation history for extension tools and subagent identity in hook inputs. (#22882, #23963)

Improved remote reliability by reconnecting stale exec-server websocket clients, retrying remote control immediately after auth recovery, and retrying remote compaction v2 streams. (#23867, #23775, #23951)
Fixed Windows TUI rendering corruption by restoring virtual terminal mode before drawing. (#24082)
Displayed workspace-specific usage-limit messages for credit and spend-cap failures. (#24114)

Preserved active permission profile metadata when syncing auto-review runtime settings. (#23956)
Ensured Node-based tools honor Codex’s managed network proxy environment. (#23905)

Documented the curl and PowerShell installer paths in the README. (#24106)
Updated developer docs to prefer just test over direct cargo test for repo-local test runs. (#23910)
Added profile migration documentation links to relevant config errors. (#23879)

Simplified release packaging around canonical native artifacts, reusable DotSlash fetching, and a new macOS x64 zsh artifact. (#23833, #23836, #24129, #24165)
Added release-build support for Codex-produced V8 artifacts. (#23934)
Added image re-encoding benchmarks and connector-style JSON schema policy fixtures. (#23935, #24152)
