## Version history (last 5 releases)

### 1.6.1 — 2026-09-18

A faster editor for big files.

• Typing stays responsive no matter how large the document gets.
• Syntax highlighting now works on files over 100 KB. It colors what you are looking at and follows along as you scroll.
• Large files open much faster, and comparing long documents no longer stalls.
• The line number gutter now numbers the last empty line, including in a brand new document.
• Fixed two freezes on large input in Punycode Decode and Unicode Unescape.

### 1.6.0 — 2026-09-14

Markdown 미리보기

Markdown을 렌더링해서 봅니다. iPad에서는 에디터 옆에, iPhone에서는 에디터와 번갈아 표시됩니다. 제목, 목록, 체크박스, 표, 인용, 이미지, 문법 강조된 코드 블록을 지원합니다. 미리보기를 길게 누른 뒤 끌면 블록을 선택할 수 있고, 서식을 유지한 채 복사해 Pages나 메모, 메일에 붙여넣을 수 있습니다. Apple의 Markdown 파서를 사용하므로 문서 안의 내용이 실행되지 않고, 원격 이미지를 불러오지도 않습니다.

변경 이력

'이력' 탭이 생겼습니다. 텍스트에 적용한 변환, 붙여넣기, 지우기, 파일 열기를 최신순으로 모두 보여주며 이름, 실행 시각, 늘거나 준 글자 수를 함께 표시합니다. 항목을 누르면 그 시점이 지금과 어떻게 다른지 확인하고 그 상태로 되돌릴 수 있습니다. 건너뛴 단계는 다시 실행할 수 있게 남고, 이력은 탭마다 따로 보관됩니다.

여유가 생긴 화면

iPhone 하단 바를 7칸에서 4칸으로 줄여 자주 쓰는 동작을 누르기 쉬워졌고, 줄 번호는 처음에 꺼진 상태로 시작합니다. iPad는 주요 동작을 툴바로 옮겼습니다. 비어 있는 패널은 무엇을 담는 곳인지 알려주고 시작할 방법을 제시하며, 커서와 선택 영역, 현재 줄에 앱의 강조 색이 들어갑니다.

주요 수정

무엇을 적용해도 차이 보기 시트가 '변경 없음'이라고 표시했습니다. 이제 실제 비교 결과가 나옵니다.

앱 안의 '언어' 설정이 앱 전체에 적용됩니다. 변환 도구 분류 이름과 오류 메시지, 시스템 경고창은 그동안 기기 언어로 나왔고, 35개 메시지는 어떤 언어에서도 영어로 표시됐습니다.

이메일 추출, HTML 태그 제거, HTML을 Markdown으로, Markdown을 HTML로 변환이 큰 입력에서 멈췄습니다. 99 KB 문서의 이메일 추출은 86초가 걸렸지만 이제 기다릴 필요가 없습니다.

사이드바가 '변환 도구' 제목의 시트 아래에서 AI 패널을 여는 문제를 고쳤고, 대체 텍스트가 없는 이미지는 VoiceOver에서 대체 문자 대신 '이미지'로 읽힙니다.

### 1.5.1 — 2026-08-30

Fixed bugs

### 1.5.0 — 2026-07-11

TextNova 1.5 brings a fresh identity, new transformers, and a faster editor.

NEW
• All-new Blue-White Star identity: new app icon and a refreshed design built on a unified design system
• 3 new transformers complete the conversion matrix: XML → JSON, JSON → XML, and HTML → Markdown (148 total)
• Manual syntax highlighting: tap the new Syntax pill to pick a language when auto-detection isn't enough
• Open files directly from the Files app and share sheet: TextNova now registers for .txt, .md, .json, and more
• On Mac: an all-new native shell with Liquid Glass, transformer Recents, tab switching with ⌘1-⌘9, and repeat-last-transform (⇧⌘R)

IMPROVED
• Bigger, touch-friendly sidebar menus on iPhone and iPad
• AI Transform now explains why it's unavailable (downloading, unsupported, or disabled) and re-enables without relaunching
• Big-document performance: line numbers, syntax highlighting, and transformers are much faster on multi-MB text

FIXED
• 30+ fixes across transformers, editor state, and views, including data-loss guards, YAML/TOML edge cases, and crash fixes

### 1.4.0 — 2026-06-07

• 27 new transformers — now 107+ in total. New encoders and converters: Base45, Base62, Roman numerals, ROT5 / ROT18, Bacon cipher, CRC16, Adler-32, FNV-1a, chmod (octal ↔ symbolic), CSV ↔ Markdown tables, RGB ↔ HSL, and Number to Words.

• Safer & sharper — Markdown → HTML now blocks unsafe HTML and links, and many JSON / YAML / TOML / CSV / XML / SQL edge cases are fixed, along with several decoder crashes.

• Smoother editing — syntax highlighting no longer drops keystrokes during fast typing.

Thanks for using TextNova!
