Changelog

This site is the work, not just the container for it. Every release since the first deploy is logged here — what shipped, what broke, and what I fixed.

23 releases

Currently on v4.18

Updated Aug 2026

v4.18 · August 24, 2026

Type and contents

  • Case studies have a chaptered table of contents: sections nest under the part of the story they belong to.
  • The changelog and style guide got the same contents panel, and the section you're in is marked in the page's own colour.
  • Every line where two typefaces meet now sets at one letter-spacing.
  • Captions, list items and small labels space the same as the copy beside them.
  • Impact numbers re-cut for the size they actually render at, not the size they used to be.
  • The changelog's version and date travel down the page beside their own release.
  • Release notes are shorter here, and stick to what shipped.
  • The site hands search engines and AI assistants a plain map of how it's organised.

v4.17 · August 19, 2026

Two families

  • New typefaces: headlines and ledes are now Lyon, everything else is IBM Plex Sans.
  • Two families instead of three unrelated ones — one sets the voice, one does the work.
  • The lede went back to a serif, in the cut actually drawn for reading at that size.
  • Body copy stayed a sans on purpose: it sits beside interface screenshots, not in a magazine.
  • New essay: A typography rebuild — from five faces to two families.
  • A line on the home and about pages that says the job in one sentence: I build the system a product gets made with, then ship it in production React.
  • Maxematics is live at maxematics.org, and the study links the client's own domain.
  • An editing pass across every case study and essay.

v4.16 · August 18, 2026

Three faces, one voice

  • The type system went from five typefaces to three: a display serif, a label sans, a reading sans.
  • Headlines no longer change face mid-sentence — one voice per line, one emphasis at most.
  • Two retired faces left with it, and 145 KB of font files off the first paint.
  • The display and label faces are now two halves of one family, drawn on the same skeleton.
  • Code snippets in the writing set in the system monospace, rather than pulling in a fourth face.
  • The AethrDesign study now shows the delivery system instead of describing it: the file behind an engagement, next to the client page it renders into.
  • You can open that client portal yourself — a real one, frozen at the date the study describes.
  • The Entagile homepage shows as three columns side by side instead of one long scroll.
  • New Side projects section on the about page — the lab, and the tools this site is built out of.

v4.15 · August 17, 2026

A seat on someone else's team

  • The AethrDesign study makes a different argument: the leverage doesn't replace a team, it travels.
  • New section — the work at Arca Wealth, an ongoing design-engineering seat on their growth pod.
  • Their board, their ticket, their Slack thread: three exhibits from inside someone else's org.
  • The About timeline names it too.

v4.14 · August 11, 2026

The capstone that started the pivot

  • New case study: a 2021 cognition experiment, built in MATLAB and submitted to an electrical engineering department.
  • It ships with two documents in English — a method-and-findings paper and a programming walkthrough deck.
  • The SUSTech row on /about now opens the study instead of leaving the site.
  • Hosted PDFs open in the in-page viewer again; they had been rendering blank.
  • PowerPoint previews resize with the window, so a whole slide fits at any width.
  • The style guide's colour swatches read straight from the stylesheet, so the page can't drift from the code.

v4.13 · August 5, 2026

The résumé lives here now

  • The Résumé link serves the current PDF from this site.
  • cheviszhou.com/resume is a permanent address — the PDF behind it can be updated without breaking a link already sent.

v4.12 · August 3, 2026

Experience on /about

  • New Experience timeline — six eras of work history, newest first, with what each company actually was.
  • Companies with a case study link straight to it.
  • The 2021–2023 internships ship as one banded era, the way they happened — three back-to-back internships through the Human Factors master's.
  • Added the 2016–2021 undergraduate entry: a MATLAB PsychToolBox cognition experiment submitted to an electrical engineering department.
  • Link to the full résumé at the foot of the section.
  • Every page points search engines at its one canonical address.
  • Keyboard focus outlines hold their contrast on every accent colour.
  • Every page carries its preview image and site name when shared.

v4.11 · July 30, 2026

The Treevah study

  • New case study: Treevah — cloud file-manager navigation and the design operation that scaled it.
  • Two movements on one page: the product decisions that settled depth and selection, then the design system and operating model that shipped them.
  • Carousels, lineage stills, and a recorded interaction video from the Cloud Alpha work.

v4.10 · July 29, 2026

The AethrDesign study

  • New case study: AethrDesign, my AI-native design practice.
  • Client deliverables run live inside the page — the Rets AI animation set plays through its own runtime. Click a card to pause it.
  • The planning graph the study was built on is on the page too, and you can hover it to read every decision.

v4.9 · July 27, 2026

Faster images, label fixes

  • Case-study images now show a preview while they load, instead of an empty frame.
  • Images load faster on a first visit — the heaviest studies no longer lag behind a fast scroll.
  • Fixed overlapping Before/After and Light/Dark labels on drag-comparison images.
  • Fixed a case-study detail note that was rendering twice.

v4.8 · July 22, 2026

The avatar waves back

  • Hovering my avatar now raises a hand — a small wave on the home page, a friendlier one on About.
  • Replaced the click-to-play intro video on the About page.

v4.7 · July 17, 2026

Colophon popover

  • The footer's build-stack details moved into a small popover behind the word Colophon.

v4.6 · July 16, 2026

Skills map

  • New lab page: an Obsidian-style graph of all 56 agent skills behind this site.
  • The map traces each skill from where it's authored or licensed to every AI runtime that executes it.
  • Hovering a node lights up its neighborhood, the way a vault graph does.

v4.5 · July 16, 2026

Writing, sorted

  • New essay: I stopped typing code. I started directing it.
  • Essays are now grouped by topic — Process, Craft, Tools.
  • Rebuilt the writing index so each topic labels its own group down the left margin.
  • Essay summaries wrap at a readable line length instead of running the full width.

v4.4 · July 15, 2026

Materials, RSS, and this page

  • This changelog.
  • Case studies host their own PDFs, decks, and papers — they preview in the browser instead of downloading.
  • Paper covers are clickable.
  • Added an RSS feed for the writing.

v4.3 · July 13, 2026

Case-study craft pass

  • Links inside a section no longer outrank that section's own header.
  • Case-study metadata moves next to the section it describes.
  • Paper covers get a printed-page lift — soft shadow, hairline edge.
  • Added local editing tools: right-click a screenshot in development to swap or re-caption it.

v4.2 · July 9, 2026

Site-wide audit

  • Every claim on the site now traces to a source record, and the record is the one the case studies are written from.
  • Entagile gained a before/after homepage comparison.
  • Two new essays.
  • Screenshots can sit in a browser frame — a real Safari toolbar, drawn rather than screenshotted.
  • Added a skip-to-content link and a styled 404.

v4.1 · July 8, 2026

Nebula V2

  • The Lab graph restructures around meaning, not folders: six life domains at the core, tools in an outer ring.
  • Selecting a node lights its whole ancestry and the tools that touch it.
  • New activity panel — sessions, messages, tokens, 26-week heatmap.
  • Fixed the background haze: the renderer was skipping a color-space conversion and lifting the blacks.

v4.0 · July 6, 2026

Lab ships

  • /lab is now CHEVIS.OS — a 3D map of the AI system I actually run: a 385-concept knowledge graph plus the skills, scripts, and projects wired into it.
  • Built from a real snapshot of my machine. None of it is mock data.
  • Boot sequence, magnetic cursor, click-to-focus drilldown.
  • Collapses to one scrollable stack on phones; honors reduced-motion.

v3.0 · July 1, 2026

Writing ships

  • /writing goes live with the first essay — Clone, then diverge.
  • Open Graph cards, sitemap, robots.txt — all derived from the content, so new work is included automatically.
  • Separated the two Solara studies: distinct openings, no shared metrics.
  • Raised the minimum type sizes on small screens.

v2.1 · June 24, 2026

Solara case studies

  • Both Solara case studies land.
  • Text selection picks up each study's own accent colour.
  • Cut the heading scale down a step to restore the gap under the hero.

v2.0 · June 23, 2026

About and contact

  • Added the about page and a working contact form.
  • Content updates across the case studies.

v1.0 · June 22, 2026

Initial deploy

  • First deploy. Case studies in MDX, a fluid type and spacing system, video and Lottie players.
  • Drew inspiration from a range of portfolios — the type system owes the most to Kyle Conrad's.
