ClineCLI 3.0.40Jul 13, 2026

Added a manual API key escape hatch for Cline OAuth providers, so you can enter a key by hand from settings

  • Fixed provider config not reloading when switching models
  • Fixed auto-update failing to detect Bun global installs after symlink resolution
  • Fixed unexpected logouts caused by transient network or server errors during token refresh

Cline4.1.18Sep 16, 2026

Images attached to a model that cannot read them are now flagged instead of silently discarded.

  • Thumbnails get a warning badge and the composer explains that the images will be ignored, with a button to switch to an image-capable model.
  • Previously the thumbnail looked normal and the image was replaced with a text placeholder just before the request, so there was no way to tell it had been dropped.
  • Model info and the attachment picker also report image support accurately for models that declare text-only input without listing capabilities.

Added

  • Images attached to a model that cannot read them are now flagged instead of silently discarded. Thumbnails get a warning badge and the composer explains that the images will be ignored, with a button to switch to an image-capable model. Previously the thumbnail looked normal and the image was replaced with a text placeholder just before the request, so there was no way to tell it had been dropped. Model info and the attachment picker also report image support accurately for models that declare text-only input without listing capabilities.

Fixed

  • On Windows, opening a repository that contains a file named rg.exe, git.exe, or powershell.exe no longer runs that file in place of the real program. Bare program names were resolved through the workspace directory before PATH, so a planted executable ran with your privileges as soon as the workspace was indexed. Cline now sets Windows' NoDefaultCurrentDirectoryInExePath opt-out at startup, in both the VS Code extension and the JetBrains core. Processes Cline launches inherit it, so inside a Command Prompt shell a program in the current directory now needs . as it already does in PowerShell.

ClineCLI 3.0.39Jul 9, 2026

You can now select Cline free models on the ClinePass provider in the model picker

  • Removed the retired ClinePass GLM 5.1 model
  • Fixed OpenAI Codex model metadata under the GPT Subscription provider
  • `str_replace` edits now report accurate diffs
  • Fixed context compaction so canonical session history is preserved

ClineCLI 3.0.38Jul 7, 2026

New plan/act accent palette: act mode is now blue (`#79b8ff`) and plan mode amber, replacing the old cyan/yellow — applied across dialogs, the model selector, config, onboarding, markdown, and syntax highlighting, with light-theme variants tuned for contrast

  • Restyled chat input: a minimal frame with full-width horizontal rules and a bold accent prompt glyph instead of the tinted background, plus slimmer user-message bubbles
  • Assistant markdown accents are now tinted by the mode (plan/act) they were produced in
  • Polished the status bar usage display and ClinePass model name
  • +4 more changes

  • Polished the status bar usage display and ClinePass model name

  • Harmonized the success/diff green and dark syntax-highlighting colors with the new brand palette

  • The thinking-level picker now defaults its cursor to Medium instead of Off

  • read_files now tolerates malformed input from weaker models: line-range entries (start_line/end_line) sent as separate array items are coalesced back onto the preceding file path instead of being rejected (from SDK v0.0.58)

  • Models in the live catalog that don't report a context window now default to a 128K input-token limit, so under-specified models get a usable context budget (from SDK v0.0.57)

ClineCLI 3.0.37Jul 4, 2026

Weaker models (e.g.

  • DeepSeek) that emit malformed tool calls — wrong argument types or truncated JSON — are now handled gracefully and run instead of erroring out
  • Plan/act mode switches are now visible to the model, so it knows when you change modes mid-session
  • Fixed plan/act mode notices being dropped from prompts sent to the model
  • Fixed a race where switching modes in an empty session could trigger an unexpected restart

ClinePass is now enabled for all CLI users

  • Recover missing interactive sessions when reading messages
  • Format structured commands in history export

  • Add Tencent TokenHub as a provider (from SDK v0.0.55)

  • Use a curated default when migrating legacy provider settings (from SDK v0.0.55)
