Changes since v0.18.1.

Early release. In SemVer terms, anything may change before 1.0, including file formats, the HTTP API and settings, though changes to .ochx and .och files will come with conversions.

New

  • Background chart plugin (#289). It draws the view's moments as a smooth curve behind the timeline, highest where the most moments lie, in a color set on the plugin.
  • Chart series and the Log severity chart plugin (#434). A background chart can draw series of tagged moments beneath its total, each stacked on those before it. Log severity chart draws one series each for errors, warnings and information. Series are drawn only from the moments the browser already has; a summary of many counts toward the total alone.
  • Timelines from files, in the desktop app (#433). From files… makes a timeline from the files in chosen folders, searched recursively if you like. Each file is dated by when it was created or modified, or, for photos, videos and sound, by when it was recorded. GPS locations are added only if you turn them on. A moment's file opens in its own app, or shows in its folder. Local file links are never sent to a server, and servers refuse them.
  • Photo thumbnails, in the desktop app (#440). With the new File thumbnails plugin, which From files… installs, a photo's moment shows a small picture of it. The picture comes from the photo's own embedded preview, or else from the photo scaled down. Thumbnails are cached on your computer and never saved into the timeline.

Fixed

  • Moment pages for search engines (#436). Moments and durations are described as a work covering their time, not as an Event, which search engines expect to have a venue and tickets.
  • Landing page videos (#432) fill the page's column, so YouTube plays them sharper.

Upgrading

Install the new package and run openchronology-migrate as usual. This release has no database changes.
