Changelog

Article list items now use the same styling patterns as the Tasks

plugin: item-card class with ThemeRadiusMd corner radius, 10,8 padding,

and selected-state styles (ThemeHoverBrush background + subtle shadow)

matching the ListBox.sidebar ListBoxItem:selected pattern.

Category tags in both the list items and detail view now use

ThemeHoverBrush background with ThemeSecondaryBrush foreground and

ThemeRadiusXs corners — identical to how task tags are rendered.

Replaced all hardcoded CornerRadius="12" and CornerRadius="6" values

with ThemeRadiusMd dynamic resource for consistency across sidebar

feed buttons, empty state, summary box, and reader error panel.

HasDistinctSummary was comparing the full summary (including trailing

"...") against the content via StartsWith. Since the content doesn't

contain "..." at the truncation point, the match always failed and

the redundant preamble kept showing.

Now strips trailing "..." from the summary before the prefix comparison.

Parse <category> elements from RSS/Atom feeds into a new Categories

field on RssArticle. Both FetchFeedAsync and RefreshFeedAsync now

extract category terms via SyndicationItem.Categories.

Article detail view shows category tags as styled pills below the

author/date line. Article list items also display compact tag labels.

Tag filter dropdown in the toolbar lets users filter articles by any

tag present in the current article set. Clear button resets the filter.

Summary preamble box is now hidden when the summary text is just a

prefix repetition of the article content — detected via normalized

plain-text comparison in HasDistinctSummary on RssArticle. This

prevents the redundant preamble block seen with feeds like the

PrivStack changelog where summary == content.

Version bump 1.9.6 → 1.10.0

Root cause: .NET's HttpClient resolves DNS and tries connecting to the

first address returned (typically IPv6 AAAA record). When the network

cannot route to the IPv6 address, the connect attempt blocks for the

full request timeout (30-60s) before giving up — unlike curl which uses

Happy Eyeballs (RFC 8305) to try both protocols in parallel.

Confirmed by testing: IPv6 connect to privstack.io hangs indefinitely

while IPv4 connects in ~45ms. This affects any host that publishes

AAAA records not routable on the user's network.

Fix: replace the default SocketsHttpHandler with a custom ConnectCallback

that implements Happy Eyeballs — resolves all addresses (IPv4 + IPv6),

initiates connections to all in parallel, uses whichever succeeds first,

and cancels the rest. This brings feed fetch from timeout (30-60s) down

to ~350ms for affected hosts.

Also adds gzip/deflate decompression support to the handler.

• Use HttpCompletionOption.ResponseHeadersRead in FetchFeedAsync and

RefreshFeedAsync so the response streams immediately after headers

arrive, enabling progressive XML parsing instead of buffering the

entire body first

• Add OperationCanceledException catch clauses that distinguish between

HttpClient timeout (user-friendly "server may be slow or unreachable"

message) and explicit user cancellation

• Increase default HttpClient timeout from 30s to 60s since RSS feeds

from smaller servers can be slow, and streaming now provides visual

feedback during the wait

• Add CancellationTokenSource to AddFeedAsync in RssViewModel so users

can cancel a slow feed fetch via CancelAddFeedCommand
