# Changelog

## 1.3.0 · 2026-10-17

### Changed
- Canonical host corrected to **copilotinexcel.jardenberg.net** (the earlier host was missing a letter). Canonical links, Open Graph URLs, sitemap, robots, llms.txt, Markdown reading copies and the social image now carry the corrected host. The old host remains connected to the same project during the transition.

## 1.2.1 · 2026-10-17

### Changed
- Set-up page reframed from "Then never again" to "Then a short review now and then": settings evolve, ten minutes now and then, like a performance review with a colleague. Nav label is now "02 · Set it up". A calendar reminder added to the checklist.
- Teach it how you work: headline "Give feedback to your Copilot colleague. Then keep giving it", with a closing note on returning to the settings as work and Copilot change.
- "Coworker" replaced by "colleague" throughout.

## 1.2.0 · 2026-10-17

### Added
- Downloadable ZIP with the three "0000" demo workbooks (145 claims, 280 support cases, 481 warranty-and-goodwill entries, synthetic) and a README, on the start page.

### Changed
- Stronger push to use your own sheets and your own work: start page principle, Door 1 introduction, the first-hour set-up block, and a source note describing the demo data as a sandbox, not the point.

## 1.1.0 · 2026-10-17

### Added
- Novare co-branding in the sidebar (logo, "in collaboration with", Oskar Elfner listed next to JJ), as on the Never Stop Learning companion.
- Two doors: three ways to get files into Copilot Chat (slash, plus sign, or just ask), with JJ's own "Find the three Excel files that begin with 0000" screenshot and prompt; a note on talking to Copilot instead of typing.
- Two doors: new "Around the corner" section on where Claude is taking spreadsheet work and data visualisation, and why that forecasts Copilot features.

### Changed
- "On this page" contents are open by default on every page.
- The former "Around the corner" map (Analyst, Cowork, Excel Agent, Python) is now "Over the hill", framed as the other side of the learning curve.
- Set-up: Copilot no longer requires the workbook to be in the cloud; AutoSave still does.

## 1.0.1 · 2026-10-17

### Fixed
- Copy buttons return to their own label ("Copy rules", "Copy text", "Copy file") after copying instead of always reverting to "Copy prompt".

### Changed
- Published host copilotinexel.jardenberg.net connected as a subdomain of the Lovable-managed jardenberg.net; Lovable badge hidden and visitor analytics turned off in project settings.

## 1.0.0 · 2026-10-17

### Added
- Eight public pages: start, two doors (Copilot Chat versus Copilot in Excel), set-up, teach it how you work (Customise Copilot, Excel Personalization, workbook rules, skills), every button explained, 24 prompts, a one-hour practice plan with the Convoy #4 homework and four-line share-back, and sources.
- Fifteen screenshots from JJ's own Microsoft 365 account on the demo workbook, taken 17 October 2026, with private items blurred.
- Copyable standing instructions, Excel personalization text, three workbook rule sets, a complete SKILL.md example and 24 prompts, each with a copy control.
- Markdown reading copy for every page, llms.txt, sitemap, robots, 404 page, light/dark/system appearance.
- Release check script (version agreement, links, anchors, copy targets, reading copies, image sizes).

### Notes
- Product claims checked against Microsoft Support, Microsoft Learn and Microsoft 365 blog pages on 17 October 2026; links on the Sources page.
- No analytics, sign-in or data collection. No session recording or transcript published.
