DemoViewer.NET v0.7.2

What's new in 0.7.2

A maintenance release built on new parser and analysis packages. One fix in it is worth upgrading
for on its own.

Demos that used to fail analysis outright now work. Some demos died with an unhandled error the
moment analysis started — not a degraded result, no result at all. The cause was a frame sharing a
tick with a checkpoint the analyzer had picked, and across a corpus spanning every protocol version
in a real matchmaking replays folder it took out 6 of 15 demos. All 15 now analyze. If you have a
many-core machine you were far more likely to hit this: the analyzer picks more checkpoints the more
cores you have, so above roughly 32 logical cores nearly every clash landed, while the same demos
were fine on a 10-core box. That is also why it was hard to reproduce from a bug report.

Analysis is faster and much lighter on memory. Against 0.7.1, measured as the median of three
runs across nine demos: parsing is about 25% faster, evaluation about 13% faster, and total
allocation is down between a third and a half.

A dead player's entity reference no longer resolves to the wrong entity. One of the two
"no such entity" markers was not being recognized in the app's read-only entity view, so instead of
reading as empty it resolved to whatever happened to occupy that slot.

The "What's new" window no longer opens before the app does. On the launch after an update it
could appear ahead of the main window.

What was new in 0.7.1 and earlier

0.7.1 was a maintenance release: the parser and analysis engine moved out to
CS2DemoKit and are consumed from nuget.org as packages,
shrinking the source tree here by roughly a hundred thousand lines, and the editor schema file for
rule authors became cs2demokit-rules.schema.json (existing dv-rules.schema.json references keep
working).

0.7.0 was the open-source debut: the source moved to a public repository under MIT, releases
and auto-updates began coming from it, damage stats stopped overcounting same-frame burst hits, and
analysis allocation dropped by roughly half.

0.6.0 turned the update offer into a full release-notes window with a once-per-update "What's
new" screen, added a damaged-demo banner, made Settings navigable with a jump-chip strip, checked
for ffmpeg before reels start, extended every theme to all surfaces, and added keyboard shortcuts,
window-state memory, and humane error messages.

0.5.2–0.5.4 brought the in-app updater, the Match Overview landing page with a bundled sample
match, a first-run walkthrough, roughly 24× lower memory after closing a demo, rich play-based
highlights with in-app reels, and a long list of scoring and roster correctness fixes.

Install

Download the one installer for your platform — nothing else is required:

• Windows — …-win-Setup.exe
• macOS (Apple Silicon) — …-osx-Setup.pkg
• Linux (x64) — the …-linux…AppImage

Each installer is self-contained: it bundles the .NET runtime and the map assets, so a single download has everything.

This build is unsigned (signing is planned):

• macOS — right-click the app → Open on first launch.
• Windows — at the SmartScreen prompt, click More info → Run anyway.

The .nupkg, RELEASES*, and releases.*.json files below are what the in-app updater reads — you don't need to download them by hand.
