Cotabby 0.5.1-beta

Highlight: mid-word completions no longer insert a stray space

The biggest user-reported bug in Cotabby is fixed. Previously, accepting an inline suggestion in the middle of a word inserted an extra space (typing after and tabbing afternoon produced after noon). Tab now inserts exactly the ghost text you see, so partial-word completions land cleanly.

This single fix closes 17 reported issues of the same defect: #621, #620, #617, #615, #614, #559, #557, #553, #548, #547, #525, #491, #479, #395, #549, #543, #507. Tracked in #623, fixed by #622.

Huge thanks to everyone who reported, reacted, and stuck with us on this one: @BNoiZe, @Cr0wTom, @creativetags, @EzraCerpac, @fxPPC, @idiked, @join3r, @justinjakull, @lukas-runge, @Marcelony, @neominik, @salmanuc, @tiekuhn.

Cotabby 0.4.2-beta

🚀 Cotabby 0.4.2-beta

This is one of Cotabby’s biggest quality releases yet.

Cotabby 0.4.2-beta focuses on making completions feel faster, cleaner, safer, and more useful in real writing. This release upgrades emoji autocomplete, adds tighter suggestion-length controls, improves OCR visual context, hardens model downloads, and lays the groundwork for a stronger open-source base-model pipeline.

✨ Headline Features

😄 Smarter emoji autocomplete

Emoji completion is now much more natural. Cotabby now supports recents, synonyms, fuzzy matching, and popularity ranking, so partial inputs like :smil, :party, :thanks, or :+1 are more likely to return what you actually meant.

⚡ New 2–4 word suggestion preset

A new short suggestion preset gives you tighter, lower-distraction completions when you want Cotabby to stay fast and lightweight.

🛡️ Better completion safety

Cotabby now applies stronger last-mile output safety gates before showing ghost text. These help suppress duplicated text, unsafe insertions, awkward sentence-boundary issues, and completions that do not fit the current field.

🧠 Stronger local model foundation

This release includes major internal work toward Cotabby’s open-source base-model path, including:

• Prompt budgeting
• Token-aware context handling
• Constrained decoding experiments
• Beam search
• Vocabulary profile caching
• Fill-in-middle prompting
• Better empty-completion diagnostics

Some of this remains behind feature flags, but the foundation is much stronger.

👁️ Cleaner visual context

Visual-context OCR is now simpler and more reliable. Cotabby removed the old LLM-based OCR summarizer path and replaced it with direct OCR hygiene filtering, including per-line confidence handling.

Result: a faster, cleaner, less fragile context pipeline.

⚙️ Better app controls

Cotabby now includes:

• Open at Login toggle
• Performance settings pane with opt-in latency tracking
• Better menu bar and Settings behavior
• Reduced AX capability flicker
• Safer handling around secure fields
• Fixes for Calendar popovers and overlay crashes

🔒 Hardened model downloads

Model download integrity checks are now stronger, helping protect users from incomplete or corrupted model downloads.

🐛 Notable Fixes

• Fixed rapid Tab sometimes leaking into the host app after accepting the final word.
• Fixed focus polling dismissing Calendar’s event popover.
• Fixed an overlay crash found during pre-release audit.
• Fixed dead settings and dead visual-context state.
• Fixed broken test scaffolding after visual-context cleanup.
• Fixed constrained-decoder latency regressions by bounding top-K work and skipping unused computation.
• Reverted constrained decoder as the only llama decode path after testing showed it was not ready to fully replace the existing path.
