-I'm pleased to announce hledger 0.27!
+Attention, attention hledger-folk! Once again, Happy Hallowe'en. After
+almost 10 years of steady development, I am very pleased to announce:
+hledger's 1.0 release!
 
-hledger is a cross-platform program for tracking money, time, or any
-other commodity, using double-entry accounting and a simple, editable
-file format.  It can also read CSV or timelog files, and export CSV.
-It provides command-line, curses and web interfaces, and aims to be a
-reliable, practical tool for daily use.  It is inspired by and largely
-compatible with ledger(1).

-This release introduces hledger-ui, a new curses-style interface that
-I'm quite pleased with (not yet available on Windows). Built on vty
-and the new brick library, it lets you review account balances and
-transactions with fewer keystrokes and less effort.
+About the project: hledger is a cross-platform program for tracking
+money, time, or any other commodity using double-entry accounting and
+a simple plain text file format. Inspired by Ledger CLI, hledger
+provides command-line, curses and web interfaces, and aims to be a
+reliable, practical tool for daily use.
 
-Also, we can now report current value based on market prices (hurrah);
-wide characters are displayed properly; regular expression account
-aliases are fast; and unix man pages are provided. You can see all
-changes at http://hledger.org/release-notes#hledger-0.27 .

+Simon Michael, Dominik Süß, Thomas R. Koll, Moritz Kiefer,
