+# Changelog
+
+## 1.0.0 — 2026-09-27
+
+The first release of the hledger plugin for Discourse. Put an
+[hledger](https://hledger.org) journal in a fenced `hledger` code block in the
+first post of a topic, and the block is replaced by a live, filterable report
+dashboard, generated on demand by the server's `hledger` executable.
+
+### Reports
+
+The dashboard offers five views, each generated from hledger's machine-readable
+JSON output:
+
+- **Accounts** — the full balance tree, with every parent account expanded.
+- **Balance sheet** — assets, liabilities and equity, folded into sections.
+- **P&L** — revenues and expenses.
+- **Equity** — a per-commodity distribution of contributed capital.
+- **Journal** — a transaction log with each posting.
+
+### Account trees
+
+Accounts are shown as a tree: every name is capitalized, nested accounts are
+indented by depth, and on the balance sheet and P&L the matching top-level
+account is folded into the section heading instead of being repeated. Empty
+titled sections show a "No data" placeholder rather than a bare total.
+
+### Equity distribution
+
+The equity view groups balances by commodity and shows each holder's amount
+alongside their percentage share of the contributed capital — with a reminder
+that this reflects contributed capital, not legal ownership.
+
+### Mentions
+
+An account segment written as `@username` (for example `equity:@alice`) is
+rendered as a Discourse mention link, with the same profile card as mentions in
+posts. Only segments that match an existing user are linked; anything else stays
+plain text.
+
+### Display
+
+Negative balances are shown in parentheses on the Accounts view, following
+accounting convention. Journal account paths keep their `:` separators, with any
+mention segments linked inline. Reports can be filtered by a From/To date range,
+and the end date is inclusive.
+
+### Security
+
+Journals are treated as untrusted input. hledger runs with a scrubbed
+environment, a private temporary working directory, a hard wall-clock timeout,
+CPU and file-descriptor limits, and capped output. `include` and `!include`
+directives are rejected, the journal must be valid UTF-8 and within size and
+line limits, and only one journal per topic is accepted. Reports are returned
+only for topics the viewer may see, the endpoint is rate-limited to 30 requests
+per minute per IP, and results are cached per post revision.
+
+### Requirements
+
+- The `hledger` executable on the server.
+- Discourse 2.7.0 or newer.

 Render [hledger](https://hledger.org) journal reports inside Discourse topics.
 
 Put an hledger journal in a fenced `hledger` code block in a topic's first
 post. The block is replaced by a dashboard with five reports, generated live
 by the `hledger` command line tool:
 
-- Accounts and balances (a full account tree, each name capitalized)
-- Balance sheet (indented account tree under each section)
-- Profit & loss / P&L (indented account tree under each section)
-- Equity distribution (account tree with per-commodity shares; contributed
+- 📋 Accounts and balances (a full account tree, each name capitalized)
