Version 1.3.25

[maboa]

• Whisper uses transformers.js 4.2.0 rebuilt with the GPU-memory fix from Fix Whisper WebGPU memory leak during generation huggingface/transformers.js#1755, vendored in js/vendor/ with its patch and build notes. Unpatched, the same build is byte-identical to jsDelivr's 4.2.0. GPU memory now stays flat: Small and Large v3 Turbo each transcribed a 54-minute file at about 3 GB, where Small previously froze a Mac on a 10-minute file. Provenance records the engine as 4.2.0+pr1755.
• Whisper Small and Large v3 Turbo are back in the model menu.
• Settings ▸ Experimental features: a switch, with a warning, for features still being tested. Hidden while nothing uses it.
• Search: what you type must be there, what you don't type is ignored. Spaces typed around a word make it whole-word (" um " no longer matches "umbrella"), typed punctuation must match ("U.S." no longer matches "us"), and replacing a word with nothing takes its punctuation with it.
• The Hyperaudio JSON export is named after the project, and the TXT, Markdown and Word exports name files the same way as the other downloads.
