-2783.docs:
 The "key-generator" node type has been removed. This was a standalone process
 that maintained a queue of RSA keys. Clients could offload the key-generation
 work by adding "key_generator.furl=" in their tahoe.cfg files, to create
 mutable files and directories faster. This seemed important back in 2006, but
 these days computers are faster and RSA key generation only takes about 90ms.

+The old version-1 Introducer protocol has been removed. Tahoe has used the
+version-2 protocol since 1.10 (in 2013), but all nodes (clients, servers, and
+the Introducer itself) provided backwards-compatibility translations when
+encountering older peers. These translations were finally removed, so Tahoe
+nodes at 1.12 or later will not be able to interact with nodes at 1.9 or
+older. #2784

+Tahoe's HTTP Web-API (aka "the WAPI") had an endpoint named "/file/". This

+One of the "recent uploads and downloads" status pages was using a
+Google-hosted API to draw a timing chart of the "mapupdate" operation. This
+has been removed, both for privacy (avoid revealing the contents to Google)
+and because the API was deprecated several years ago. #1942
+
+The "_appname.py" feature was removed. Early in Tahoe's history (at
+AllMyData), this file allowed the "tahoe" executable to be given a different
+name depending upon which Darcs patches were included in the particular
+source tree (one for production, another for development, etc). We haven't
+needed this for a long time, so it was removed. #2754
