v2026.6.16

Added

• Added a compaction trim benchmark suite for hard-limit emergency pruning.

Fixed

• Fixed inherited Google and google-vertex Gemini model metadata to map latest aliases to the current models, add Gemini 3.5 Flash for Vertex, correct Gemini 2.5 Flash Vertex cache pricing, and remove shut-down Vertex preview models (#5761).
• Fixed the session selector to stay open and show the all-sessions empty state when both current-folder and all-scope session lists are empty (#5747).
• Fixed inherited Moonshot AI China model metadata to include Kimi K2.7 Code, and omitted unsupported thinking-off payloads for Kimi K2.7 Code models (#5760).
• Compaction now keeps the last valid cut point when the recent-token budget is exceeded entirely within trailing tool results, instead of silently retaining the whole history.

Changed

• Improved hard-limit emergency pruning so old-message trimming tracks a running token total instead of re-estimating the whole conversation each iteration.
• Improved extension context emission by using a JSON-only clone for the hot context message copy.
• Improved single-line intra-line diff rendering with conservative fast paths for identical, long, and single-span edits.
