 Notable changes per release. Releases before 0.4.0 are listed at
 [github.com/only-cli/oc/releases](https://github.com/only-cli/oc/releases).
 
+## Unreleased
+
+### Fixed
+
+- A feed entry's title is now the link to the entry, so `oc do <n>` on a post
+  in a subreddit feed opens it. The link used to sit beside the byline as an
+  anchor labelled `open`, the same label on every entry, and the
+  repeated-controls filter hid them all on any feed with five or more entries,
+  which left nothing in a listing that led anywhere: an agent asked to open
+  the first post's comments got the heading text back, refetched the feed
+  looking for the link, and met Reddit's 429 (#59).
+
+### Changed
+
+- `oc open` on a reddit.com front page, subreddit, post, user or search URL
+  fetches the matching www.reddit.com Atom feed when no login session is
+  held, since the HTML page ends at a login wall for a logged-out reader.
+  Following a post out of a feed lands on its comments feed instead of the
+  wall. A URL that is already a feed, any other reddit.com path, and any
+  request carrying reddit.com cookies are fetched as asked (#59).
+
+## 0.5.3
+
+### Changed
+
+- Requests to reddit.com present the Firefox fingerprint first and fall back
+  to Chrome, the reverse of every other site. Reddit's edge answers the Chrome
+  fingerprint with a 403 or a 429 while letting Firefox through, and since it
+  allows anonymous readers about ten requests a minute per address, the wasted
+  Chrome attempt was costing a real share of that budget on every read (#52).
+
+## 0.5.2
+
+### Changed
+
+- `oc reddit` reads the Atom feeds on www.reddit.com instead of old.reddit.com
+  pages. Reddit has sent every logged-out old.reddit.com request to a login
+  page since 30 June 2026, and the `.json` views on www.reddit.com have
+  answered 403 to anything without an OAuth token since 30 May, whatever the
+  User-Agent or TLS fingerprint. The feeds still answer, so `sub`, `post`,
+  `user`, and `search` point at them, and `new <name>` and `top <name>` join
+  the verbs. A subreddit renders in about 480 tokens and a thread with 22
+  comments in about 1,000. The feeds carry no scores or comment counts, and
+  anonymous reddit.com allows roughly ten requests a minute per address, so a
+  burst of shortcuts ends in a 429 that takes minutes to clear. (#52)
+
+## 0.5.1
+
+### Added
+
+- `find <query>` in every `actions:` footer, after `do <n>` and before
+  `read <n>`, the order the skill's "going further, cheapest first" list
+  already gives. One command lands on the block that matters, where `read`
+  needs the right number first and `next` pages toward it. The entry costs 3
+  or 4 tokens per render. (#46)
+
+### Fixed
+
+- `oc open` no longer dies with `Impersonating chrome150 is not supported` on
+  machines where impers loads a system copy of libcurl-impersonate older than
+  v2.1.0, which predates the fingerprint the `chrome` alias resolves to. A
+  refused fingerprint now downgrades the same way a blocked response already
+  did: chrome falls back to firefox, and when both identities are refused the
+  plain fetch transport still gets the page. Any other impers failure
+  propagates unchanged, and installs where impers works keep the newest chrome
+  fingerprint. (#40)
+- The `actions:` footer no longer offers `fill <n> <text>` and `submit` on
+  pages with an input. Both are still planned, and following the footer's
+  own suggestion always failed. A test now keeps every footer free of
+  commands that are not available yet. (#44)

 A shortcut only ever resolves to a URL and then takes the same path `oc open` does, so it changes nothing about what a page costs or how it reads. The last argument takes every word after it, so `oc ddg search claude code cli` and `oc aws search s3 lifecycle rules` need no quoting, and a path argument keeps its slashes, so `oc learn doc azure/aks/what-is-aks` reaches that page.

AWS, Google Cloud, Rust, Java, TypeScript, PHP, and cppreference render docs search client-side, or as a page too bare for oc to read, so their `search` goes through DuckDuckGo with a baked-in `site:` filter instead; Go needs no such fallback, because pkg.go.dev renders its search results on the server and `oc go search` simply opens them. Python's docs are built with Sphinx, which publishes the site's full-text search index as one static file, so `oc py search` fetches that index (cached on disk for a day), ranks it locally, and prints a numbered result list; a query that names a symbol exactly, like `json.dumps`, links straight to its anchor. The same backend will work for any Sphinx site, including most Read the Docs projects.

Node.js ships no search endpoint at all, but publishes its whole API reference as one static JSON file, so `oc node search` ranks that file locally the same way the Sphinx backend does, under the same day cache, and every module, class, method, property, and event heading links to its own anchor.

 - The budget is a target rather than a hard cap: a page that would finish within about four times it is printed whole, because a second command costs the agent far more than the lines the cut would have saved
 - The render leads with the page's main content and puts navigation, sidebar, and footer after it, so the budget is spent on what was asked for rather than on menus

 - JSON APIs render like pages: an endpoint that answers with JSON becomes one numbered item per record, with the fields that differ between items kept and the ones every item shares stated once, so a search endpoint reads like a results page for a few hundred tokens
 - A page that comes back with no readable text (JavaScript-only, a consent wall, a bot challenge) prints one line on stderr and exits 2, rather than reporting an empty render as a success. `--json` carries the same verdict as an `empty` field, so a caller can tell "nothing on this page" from "oc could not read this page" and fall back to a browser only when it is worth it
 - A shortcut is `oc <site> <verb> [args]`: `oc hn top`, `oc reddit sub ClaudeAI`, `oc gh repo only-cli oc`, `oc ddg search claude code cli`, `oc learn doc azure/aks/what-is-aks`, `oc py library json`. Name the site by its short name, bare name, or domain (`oc hn`, `oc ycombinator`, `oc news.ycombinator.com`), the last argument takes every word after it so a query needs no quoting, and `oc sites` lists every site with its verbs. A shortcut resolves to a URL and then behaves exactly like `oc open <url>`
 - X profiles and individual posts read without a login (about 390 and 260 tokens); X search, explore, and hashtag pages do not, and oc reports the block instead of guessing
 - Outbound fetches honor `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY` (and their lowercase forms), so oc works in a sandbox whose only route to the network is a proxy. An https target is tunneled with CONNECT and its certificate is still verified, credentials in the proxy URL reach the proxy and nothing else, and private or locally unresolvable targets stay refused. `ALL_PROXY` is not read
-- Requests impersonate Chrome, so pages that block plain scripts often still work

 - Agent skill included: `npx skills add https://github.com/only-cli/oc --skill web-browsing-cli` ([skills.sh](https://www.skills.sh/only-cli/oc/web-browsing-cli))
 - Authenticated pages: `printf %s "..." | oc login --cookie - --domain example.com [--expires 1h] [--session name]` seeds a timeboxed cookie jar; cookies are sent on every fetch for that session and live in a separate file from page state. `--cookie -` reads the header from stdin, which keeps the credential out of `ps` and shell history; `--domain` must be a real hostname, not a bare TLD. Seeded cookies are https-only unless `--allow-http` says the site is not, so a redirect that downgrades to `http` drops them. `oc logout` forgets that session's cookies and its saved page
 - No JavaScript rendering yet (on the roadmap)

 Prefer a shortcut over a hand-built URL when one exists for the site, and prefer `oc wiki article <title>` over a search when you already know the article's name.
