   - Use Ivy for resolving external dependencies rather than relying
     on files found in Debian stable packages. Requires installing Ivy
     (using `apt-get install ivy`, `brew install ivy`, or similar) and
     running `ant resolve` (or `ant -lib /usr/share/java resolve`).
     Retrieved files are then copied to the `lib/` directory, except
     for dependencies on other metrics libraries that still need to be
     copied to the `lib/` directory manually. Current dependency
     versions resolved by Ivy are the same as in Debian stretch with
     few exceptions.

 * Major changes
   - Simplify DescriptorReader by returning Descriptor instances
     rather than DescriptorFile instances containing Descriptors,
     deprecate DescriptorFile, and add a File reference to Descriptor.
   - Introduce a new UnparseableDescriptor to be returned by
     DescriptorParser and DescriptorReader if a descriptor cannot be
     parsed, as opposed to throwing a DescriptorParseException or
     skipping the entire descriptor file, respectively.

 * Medium changes
   - Let DescriptorParser return an Iterable instead of a List, which
     prepares parsing large descriptor files descriptor by descriptor.
176
177
178
   - Add new method to retrieve the raw descriptor length, rather than
     forcing applications to request (a copy of) raw descriptor bytes
     only to determine the raw descriptor length.

     referenced byte[], rather than copying contents into a separate
     byte[] per descriptor.

208
209
210
211
 * Minor changes
   - Turn keyword strings into enums and use the appropriate enum sets
     and maps to avoid repeating string literals and to use more speedy
     collection types.
212
   - Simplify and avoid repetition in parse helper methods.
213
214
   - Fix a bug where Microdescriptor's getDigestSha256Base64() returns
     a hex string rather than a base64 string.
215
   - Move descriptor digest computation to DescriptorImpl.
216
217
   - Fix a bug in digest computation by making sure that the
     descriptor string actually contains the end token.
218
219
220
221
   - Fix a bug where both RelayDirectoryImpl and all NetworkStatusImpl
     subclasses fail to get indexes right if parts of raw descriptor
     strings contain non-ASCII chars.  In practice, this only affects
     version 1 directories which were last archived in 2007.

     to fail descriptors containing unrecognized lines.
237

238

239
240

251
252
253
254
 * Medium changes
   - Add two methods for loading and saving a parse history file in

     after all descriptors are read but before they are all processed.

255

   - Unify the build process by adding git-submodule metrics-base in
     src/build and removing all centralized parts of the build
     process.
258
259
   - Avoid deleting extraneous local descriptor files when collecting
     descriptors from CollecTor.
260
261
262
263
   - Turn the descriptor reader thread into a daemon thread, so that
     the application can decide at any time to stop consuming
     descriptors without having to worry about the reader thread not
     being done.
264
265
266
   - Parse "proto" lines in server descriptors, "pr" lines in status
     entries, and "(recommended|required)-(client|relay)-protocols"
     lines in consensuses and votes.
267
   - Parse "shared-rand-.*" lines in consensuses and votes.
268
269
   - Deprecate DescriptorCollectorImpl now that
     DescriptorIndexCollector is the default.

     as dependency.

   - Add the Simple Logging Facade for Java (slf4j) for logging
     support rather than printing warnings to stderr.  Applications
     must provide slf4j-api-1.7.7.jar or higher as dependency and can
     optionally provide a compatible logging framework of their choice
     (java.util.logging, logback, log4j).

 * Medium changes
   - Add an alpha version of a DescriptorCollector implementation that
     is not enabled by default and that uses CollecTor's index.json
     file to determine which descriptor files to fetch.  Applications
     can enable this implementation by providing gson-2.2.4.jar or
     higher as dependency and setting property descriptor.collector to
     org.torproject.descriptor.index.DescriptorIndexCollector.

301

   - Support more than one "directory-signature" line in a vote, which

     more than one algorithm.
   - Provide directory signatures in consensuses and votes in a list
     rather than a map to support multiple signatures made using the
     same identity key digest but different algorithms.
   - Be more lenient about digest lengths in directory signatures
     which may be longer or shorter than 20 bytes.
326
   - Parse "tunnelled-dir-server" lines in server descriptors.
327

328

339
340
   - Make unrecognized keys of Torperf results available together with
     the corresponding values, rather than just the whole line.
341
342
   - In Torperf results, recognize all percentiles of expected bytes
     read for 0 <= x <= 100 rather than just x = { 10, 20, ..., 90 }.
343
344
   - Rename properties for overriding default descriptor source
     implementation classes.
345
   - Actually return the signing key digest in network status votes.
346
   - Parse crypto parts in network status votes.
347
348

     key only once in the unrecognized lines.
353

   - Make "consensus-methods" line optional in network statuses votes,
     which would mean that only method 1 is supported.

     votes.

     Compress and XZ for Java.  Applications only need to add XZ for
     Java as dependency if they want to parse .xz-compressed tarballs.

   - Introduce a new ExitList.Entry type for exit list entries instead
     of the ExitListEntry type which is now deprecated.  The main
     difference between the two is that ExitList.Entry can hold more
     than one exit address and scan time which were previously parsed
     as multiple ExitListEntry instances.
374
375
376
377
378
379
   - Introduce four new types to distinguish between relay and bridge
     descriptors: RelayServerDescriptor, RelayExtraInfoDescriptor,
     BridgeServerDescriptor, and BridgeExtraInfoDescriptor.  The
     existing types, ServerDescriptor and ExtraInfoDescriptor, are
     still usable and will not be deprecated, because applications may
     not care whether a relay or a bridge published a descriptor.
380
381
382
383
384
   - Support Ed25519 certificates, Ed25519 master keys, SHA-256
     digests, and Ed25519 signatures thereof in server descriptors and
     extra-info descriptors, and support Ed25519 master keys in votes.
   - Include RSA-1024 signatures of SHA-1 digests of extra-info
     descriptors, which were parsed and discarded before.
385
   - Support hidden-service statistics in extra-info descriptors.
386
387
   - Support onion-key and ntor-onion-key cross certificates in server
     descriptors.
388
