----------------------------------------------
+NEWS
+====
+
+----------------------------------------------
+0.5.1 (to be announced) "temporary implication"
+----------------------------------------------
+
+ - audiod improvements and fixes.
+ - buffer tree robustness improvements.
+
+----------------------------------------
+0.5.0 (2013-08-23) "invertible validity"
+----------------------------------------
+
+Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
+
+ - The sideband compatibility code has been removed, hence
+ sideband connections (introduced in 0.4.11) are now mandatory.
+ - Addblob commands can produce output.
+ - The stat command no longer sends garbage when para_server was
+ compiled against libgcrypt.
+ - Dependencies for gengetopt files are computed automatically.
+ This eliminates a constant source of build bugs.
+ - The setatt command now accepts file name patterns rather than only
+ path names.
+ - overview.pdf is now based on dia, a simple diagram creation program.
+ The new version is much more detailed and contains descriptions of
+ the various programs of the paraslash package.
+ - The separator of all multi-word options has been changed from
+ underscore to dash. For example --log_color becomes --log-color.
+ - Overhauled web pages and the new logo.

+ <dia:string>#Incoming connections arrive via TCP at the dispatcher which creates a
+command handler process for each connection.
+
+After the connecting client has been authenticated, the command
+handler propagates the incoming request either to the audio file
+selector (afs) or to the virtual streaming system (vss). Results are sent
+back to the client.
+
+afs maintans the audio file database and is responsible for selecting
+and loading audio files while vss controls the paraslash senders. When
+vss needs to stream an audio file it requests an open file descriptor from
+afs and feeds small chunks of data (e.g. mp3 frames) to the senders
+which send the chunks to all connected clients.#</dia:string>

+ <dia:string>#Metadata about all known audio files is stored in serveral tables of a
+database which is driven by libosl, the object storage layer library.
+
+The "audio files" table is the main table of the database. It contains
+path, hash and metadata of each known file.
+
+The "attributes" table maps each of the 64 possible attributes to a
+string. The attribute value of the file's metadata is translated through
+this table.
+
+The tables shown shaded are blob tables which support add, rm, mv,
+cat, ls commands. All of these are optional.
+
+The "score" table describes the subset of admissible files for the
+current playlist or mood. This table is created on demand, resides
+only in memory and is discarded on exit.
+
+When the next audio file is to be streamed, the audio file selector gets
+the entry with the highest score from the "score" table, obtains path,
+hash, and metadata for this entry from the "audio files" table, opens
+the path and verifies the hash.#</dia:string>
