+# jsonld ChangeLog
+
+## [Unreleased]
+
+### Breaking Changes
+- "request" extension moved to [jsonld-request][]. This was done to simplify
+  the core JSON-LD processing library. In particular, the extension pulled in
+  RDFa processing code and related dependencies. The old method of using this
+  exension of `jsonld.use('request')` is deprecated in favor of using the new
+  module directly.
+- The `jsonld` tool moved to [jsonld-cli][]. This was also done to simplify the
+  core JSON-LD processing library and because it uses the [jsonld-request][]
+  module.
+
+## [0.3.26] - 2015-09-01

-Using the Command-line Tool
----------------------------
 
-The jsonld command line tool can be used to:
+Related Modules
+---------------
 
- * Transform JSON-LD to compact, expanded, normalized, or flattened form
- * Transform RDFa to JSON-LD
- * Normalize JSON-LD/RDFa Datasets to NQuads
-
-To install the tool, do the following (you will need git, nodejs, and
-npm installed):
-
-    git clone https://github.com/digitalbazaar/jsonld.js.git
-    cd jsonld.js
-    npm install
-
-To compact a document on the Web using a JSON-LD context published on
-the Web:
-
-    ./bin/jsonld compact -c "https://w3id.org/payswarm/v1" "http://recipes.payswarm.com/?p=10554"
-
-The command above will read in a PaySwarm Asset and Listing in RDFa 1.0 format,
-convert it to JSON-LD expanded form, compact it using the
-'https://w3id.org/payswarm/v1' context, and dump it out to the console in
-compacted form.
-
-    ./bin/jsonld normalize -q "http://recipes.payswarm.com/?p=10554"
-
-The command above will read in a PaySwarm Asset and Listing in RDFa 1.0 format,
-normalize the data using the RDF Dataset normalization algorithm, and
-then dump the output to normalized NQuads format. The NQuads can then be
-processed via SHA-256, or similar algorithm, to get a deterministic hash
-of the contents of the Dataset.
+* [jsonld-cli][]: A command line interface tool called `jsonld` that exposes
+  most of the basic jsonld.js API.
+* [jsonld-request][]: A module that can read data from stdin, URLs, and files
+  and in various formats and return JSON-LD.
