Changelog

What has changed on Case Changer Pro, newest first. Dates are in UTC.

Live results, one Copy button, and a faster way to every tool

  • Results update as you type, so the Transform button is gone.
  • One Copy button sits beside the result and confirms when the text is copied. Clear has an Undo.
  • On the homepage the editor is at the top of the page, on phones too.
  • Each tool page offers its own example texts to try.
  • The All Tools page lists every tool from A to Z, with a filter.
  • Choosing another tool from the tool picker on a tool page now opens that tool and keeps your text.
  • Character counts above the editor count an emoji or accented letter as one character, like the stats bar.

Programming cases, tool settings, a stats bar, and title case tools that explain themselves

  • Six programming case converters: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case, with their own category and a camelCase vs. snake_case comparison.
  • Tools that used fixed values now have settings: the prefix and suffix tools, wrap width, truncate length, indent width, and spaces per tab. The defaults are the values they used before.
  • A stats bar under the editor counts words, characters with and without spaces, lines, sentences, and reading time, and counts an emoji or accented letter as one character.
  • The title case tools can show one title in AP, Chicago, APA, and MLA side by side, explain the rule behind each word, and keep words you add to a personal dictionary (such as iOS or eSIM) exactly as you type them. The dictionary stays in your browser.
  • Reading time now rounds correctly: 399 words is 2 minutes, not 1.
  • The Types of Letter Case guide covers the programming cases.

Title case rules, style comparisons, and this changelog

  • A new Title Case Rules page explains, for AP, Chicago, APA, and MLA, which edition each converter follows, the rules it applies, its known limits, and the test cases it passes.
  • New comparison pages: AP vs. Chicago, APA vs. MLA, and proper case vs. title case. The title case vs. sentence case comparison is expanded. Tool pages link to the comparison that applies.
  • The Types of Letter Case guide is expanded, with a table of which case to use when and links to each converter.
  • The About page has an author section, and this changelog lists the changes visitors can notice.
  • The title case tools link to the contact page so you can report a wrong capitalization.

Sentence case keeps brand names, and time abbreviations stay lowercase

  • Sentence case keeps words with a capital after their first letter as typed, such as iPhone, eBay, and McDonald, even at the start of a sentence.
  • Text typed with Caps Lock on, such as "tHE lORD oF tHE rINGS", is converted like ordinary text in sentence case and title case.
  • The time abbreviations a.m. and p.m. stay lowercase in every title case style. MLA used to change a final "a.m." to "A.m.".

Cleanup, accessibility fixes, and updated foundations

  • Removed unfinished features that were never completed (batch processing, history, favorites, templates, and workflows), along with copy that promised them.
  • Rebuilt the tool picker and the Categories menu in the navigation.
  • Fixed accessibility problems found by automated checks: tool counts and dark-mode hover colors in the mobile menu, the keyboard shortcut hint in dark mode, and tool picker rows in dark mode.
  • Removed footer social media links that did not lead anywhere.
  • Updated the framework and libraries the site is built on.

Proper case handles names

  • Proper case capitalizes each part of a hyphenated name (Mary-Jane) and adds the second capital in O', D', and Mc names (O'Brien, D'Angelo, McDonald).
  • Words with their own capitals, such as iPhone, eBay, and JSON, are kept as typed, and a word after an opening quotation mark or bracket is capitalized.
  • Contractions and words such as o'clock are left alone, and names that start with Mac are not changed.

One layout for every tool, categories, and a letter case guide

  • All 60 tool pages use one layout. The core case tools and the AP, Chicago, APA, and MLA tools have full pages with examples, rules, and answers to common questions, and every example is checked against the converter.
  • Tools are grouped into categories, each with its own page. Old category addresses redirect to the new ones.
  • The Types of Letter Case guide replaces the old case converter overview page, which now redirects to it.
  • The site uses one name, Case Changer Pro, everywhere, and each page has its own title and description for sharing. Each tool page has its own preview image.
  • Fixed broken links between pages.
  • The press release guide now credits its author, Robert David Orr. The privacy answer on the homepage now says that Google Analytics sets cookies; the text you convert still never leaves your browser.

Faster pages and accessibility

  • Most pages are now built ahead of time instead of on every visit, and the All Tools page loads about half as much JavaScript as before.
  • A skip link on every page, one main heading per page, a Categories menu that opens on click and closes with Escape, and color contrast that meets WCAG AA in light and dark mode.
  • One editor that adapts to phones, with stacked panels, a sticky action bar, a full-screen tool picker, and larger touch targets. The microphone button is removed.
  • Clear empties the editor right away and offers Undo.
  • The same input length limit applies everywhere.
  • The keyboard shortcut hint matches your platform (⌘K or Ctrl+K), and dark mode no longer flashes light on page load.

Security and error reporting

  • The limit on how often the site’s API can be called can no longer be bypassed with a faked request header.
  • Removed the background script that stored copies of pages in your browser. Browsers that installed it remove it, and the copies it stored, on their next visit.
  • The site can report errors that happen in your browser, without personal information, so they can be fixed.

Accurate conversions

  • Title case was rebuilt with separate rules for AP, Chicago (18th edition), APA (7th edition), and MLA (9th edition) style. It keeps acronyms and mixed-case words, handles the first and last words and the word after a colon by each style, and handles abbreviations such as a.m., Mr., and Ph.D. Plain Title Case follows AP rules.
  • Line breaks are kept, and runs of spaces are no longer collapsed.
  • Text that looks like code is no longer changed or rejected.
  • Emoji and accented or non-Latin letters are treated as whole characters, and sentence case and the counting tools find sentences the same way, skipping abbreviations and decimals.
  • Expand contractions keeps capitalization, removing line numbers no longer strips a year at the start of a line, and smart quotes are fixed after brackets and in years such as '90s.
  • Find & Replace can match case, match whole words, use regular expressions, count matches, and explain an invalid pattern.
  • If copying fails, the site says so and selects the output so you can copy it yourself.

Checks before every release

  • Every change to the site now has to pass type checks, code checks, the test suite, and a production build before it can be released.

Removed made-up content

  • Removed a star rating and testimonials that were not real, including one attributed to the Associated Press.
  • Removed "live" counters that showed random numbers, and claims that could not be verified, such as user counts, countries, and accuracy and speed percentages.
  • Fixed colors that made the logo, buttons, and footer brand invisible.
  • Addresses that do not exist now show a real "page not found" page.
