v6.45.0 Changes
June 06, 2017
🆕 New Features
```
* util-app: Optional resource shutdown sequencing for registered closables
  via `c.t.app.App#closeOnExitLast`. See longer note there for usage.
  ``RB_ID=916120``

* util-core: Added `writeBytes(Buf)` to the ByteWriter abstract class to allow
  for efficient writing of the `c.t.io.Buf` type. ``RB_ID=917094``

* ✅ util-core: Added `writeString(CharSequence, Charset)` and readString(Int, Charset)`
  to ByteWriter and ByteReader respectively to facilitate for more efficient String
  encoding and decoding. ``PHAB_ID=D63987``

* util-core: Added `ByteReader.readUnsignedLongBE` and `ByteReader.readUnsignedLongLE`.
  ``RB_ID=917289``

💥 Breaking API Changes
```
- 🚚 util-collection: Removed deprecated c.t.u.JMapWrapper. Use scala.collection.JavaConverters instead. RB_ID=915544
- util-core: ByteReader extends the AutoClosable interface to provide a notion of resource management. Users should ensure that instances of the ByteReader interface are closed after they are no longer needed. RB_ID=916086
- 🚚 util-core: Removed deprecated methods from c.t.u.Future:
  - rawException; use exception instead
  - cancel; use raise instead
Removed deprecated c.t.u.Futures.select; use Future.select instead. Remove deprecated flatten method on c.t.u.Future; use Futures.flatten instead. RB_ID=915500
- 🚚 util-core: Removed deprecated c.t.u.LongOverflowException. Use java.lang.ArithmeticException instead. Removed deprecated c.t.u.LongOverflowArith and all methods on it:
  - add; use Java 8's Math.addExact instead
  - sub; use Java 8's Math.subtractExact instead
  - mul; use Java 8's Math.multiplyExact instead RB_ID=915545
- 🚚 util-core: Removed deprecated c.t.concurrent.exp.AsyncStream. Use c.t.concurrent.AsyncStream instead. RB_ID=916422
- 🚚 util-eval: Removed from the project. RB_ID=915430 https://finagle.github.io/blog/2017/04/06/announce-removals/
⚙ Runtime Behavior Changes
```
* util-core: All `Timers` now handle negative or undefined times/durations in uniform way:
  treat them as zeros (i.e., `Time.epoch`, `Duration.Zero`). ``RB_ID=916008``
```

v6.43.0 Changes

April 20, 2017

⚙ Runtime Behavior Changes


* 🔀 util-core: `Closable.all(..)` will now catch synchronous exceptions thrown
  by any `Closable.close(..)` invocations, and wrap them in a failed Future.
  ``RB_ID=914859``

* util-stats: InMemoryStatsReceiver's `gauges` member is now safe for
  concurrent iteration but now holds strong references to gauge instances.
  ``RB_ID=911951``

🆕 New Features

util-core: c.t.f.u.BufReader and c.t.f.u.BufWriter have been moved from finagle-core to util-core and renamed to c.t.io.ByteReader and c.t.io.ByteWriter respectively. They are now also exposed publicly. RB_ID=911639

💥 Breaking API Changes


* 🚚 util: util-zk-commons was removed, since it was only a connector between
  util and commons, which was not widely used.  ``RB_ID=910721``

* util-core: AsyncQueue's `size` method is now final while `offer` and `fail`
  are no longer final. ``RB_ID=914191``

v6.42.0 Changes
March 10, 2017
🆕 New Features
```
* util-core: Promoted the positional `Buf.Indexed` API to be a first-class
  part of `c.t.io.Buf`. If you have a custom implementation of `Buf` it
  will require some effort to become compatible. ``RB_ID=907231``

💥 Breaking API Changes
```
- 📜 util-app: Set failFastUntilParsed on created flag added to c.t.app.Flags via c.t.app.Flags#add. RB_ID=908804

```

v6.41.0 Changes

February 03, 2017

🆕 New Features


* util-app: App now exposes `closeOnExit` publicly. ``RB_ID=906890``

* util-core: Add method to `Buf` to efficiently write to a nio `ByteBuffer`.
  ``RB_ID=910152``

* util-core: Add Java-friendly API to Scala.java for converting from
  a Java 8 `Optional` to a Scala `Option`. ``RB_ID=906512``

* util-core: Introduced a positional `Buf` API, `Buf.Indexed`, and retrofitted
  all existing implementations in util and finagle to adopt it. It is now used
  throughout for a reductions in allocation and latency. In two services at
  Twitter we saw a 1-2% reduction in allocations. We plan to open the API to
  the public and make it a part of `Buf` once we are confident in the APIs.
  ``RB_ID=904559`` ``RB_ID=905253`` ``RB_ID=906201``

* 👍 util-slf4j-api: Introduce slf4j-api support into util. This includes a
  small scala wrapper over the `org.slf4j.Logger` and a scala-friendly
  `Logging` trait. Changes also include the util-slf4j-jul-bridge module which
  is a library that provides a utility to "smartly" install the
  Slf4jBridgeHandler. ``RB_ID=900815``

⚙ Runtime Behavior Changes

🐎 util-core: Improved performance and allocation rates of some "random access" Buf operations. RB_ID=905253
util-core: Standardized argument checking in implementations of c.t.io.Buf.write and c.t.io.Buf.slice. RB_ID=899935

💥 Breaking API Changes


* 🗄 util-core: Deprecated `c.t.io.ConcatBuf` which is replaced by
  `c.t.io.Buf.apply(Iterable[Buf])`. ``RB_ID=899623``

v6.40.0 Changes
December 20, 2016
🐛 Bug Fixes
```
* util-core: Fix issue with c.t.concurrent.AsyncStream.mapConcurrent which
  will cause the stream head to be held for life of operation. ``RB_ID=896168``

💥 Breaking API Changes
```
- 🗄 util-core: Deprecated charset constants in c.t.io.Charsets have been removed. Use java.nio.charset.StandardCharsets instead. RB_ID=893542
- 🗄 util-core: com.twitter.util.NonFatal is deprecated, use scala.util.control.NonFatal instead. RB_ID=892475
- util-core: FactoryPool/SimplePool now inherits scala.collection.mutable.Queue[A] not deprecated scala.collection.mutable.QueueProxy[A] RB_ID=896485
- util-core: Buf has been promoted from a trait to an abstract class to facilitate memoization of the Buf hash code. This also removes the need for the Java friendly abstract class: AbstractBuf. RB_ID=897476
v6.39.0 Changes
November 22, 2016
No Changes

v6.38.0 Changes

October 10, 2016

🆕 New Features


* util-app: Java developers can now declare instances of `GlobalFlag`
  from Java. See `c.t.app.JavaGlobalFlag` for details. ``RB_ID=874073``

* util-thrift: We now depend on a fork of libthrift hosted in the Central Repository.
  The new package lives in the 'com.twitter' organization. This removes the necessity of
  depending on maven.twttr.com. This also means that eviction will not be automatic and
  using a newer libthrift library requires manual eviction if artifacts are being pulled
  in transitively. ``RB_ID=885879``

* 🌲 util-logging: Allow users to override `c.t.util.logging.Logger` installation,
  making it easier to work with SLF4J bridges. ``RB_ID=870684``

* util: No longer need to add an additional resolver that points to maven.twttr.com.
  ``RB_ID=878967``

🐛 Bug Fixes

util-core: c.t.io.InputStreamReader and Readers created by c.t.io.Reader.fromFile and fromStream now close the underlying InputStream on reading of EOF and on calls to Reader.discard. RB_ID=873319

💥 Breaking API Changes


* util-core: `c.t.app.GlobalFlag` is now `abstract` to reflect how the class
  is intended to be used. ``RB_ID=875409``

v6.37.0 Changes

September 07, 2016

🆕 New Features


* util-app: Introduce `c.t.app.Flag.letClear` allowing flags to be unset.
  ``RB_ID=868177``

v6.36.0 Changes

August 25, 2016

🆕 New Features


* util-core: `c.t.util.FuturePool` now optionally exposes metrics on
  their internal state such as active tasks, and completed tasks.
  ``RB_ID=850652``

* util-core: Add a system property
  `com.twitter.concurrent.schedulerSampleBlockingFraction` that can be
  set to a value between 0.0 and 1.0 (inclusive). When the Scheduler
  runs blocking code, it will log the stacktrace for that fraction of
  the calls. ``RB_ID=861892``

* 👀 util-core: Add Java-friendly API for `StorageUnit`. See `StorageUnit.fromX`
  and `StorageUnit.{times, plus, minus, divide}` methods. ``RB_ID=864546``

⚙ Runtime Behavior Changes

util-eval: The compiler reporter is now reset between code check invocations. This means that when there is a failure that it is no longer required to reset the entire state to recover and that already compiled and loaded classes can still be used. RB_ID=859878

v6.35.0 Changes

July 07, 2016

⚙ Runtime Behavior Changes


* util-codec: StringEncoder no longer depends on apache commons-codec, and
  decode will now throw an exception when it fails to decode a byte, instead
  of failing silently. ``RB_ID=833478``

* util-collection: LruMap is now backed by jdk LinkedHashMap instead of apache
  collections LRUMap. ``RB_ID=833515``

* util-core: `com.twitter.util.NonFatal` is now implemented by Scala's
  `scala.util.control.NonFatal`. This changes behavior such that
  `java.lang.StackOverflowError` is considered fatal and
  `java.lang.NoSuchMethodException` is considered non-fatal.
  ``RB_ID=835671``

🆕 New Features

🚚 util-app: com.twitter.finagle.util.LoadService has been moved to c.t.app.LoadService and can now be used without needing a finagle-core dependency. RB_ID=829897
💅 util-cache: Adds support for Caffeine-style caches. RB_ID=833848
⏱ util-core: Add c.t.concurrent.Scheduler.blockingTimeNanos which tracks time spent doing blocking operations. RB_ID=828289
🚤 util-core: Reduced allocations by 40% and latency by 18% of satisfying Promises. RB_ID=832816
🚚 util-core: c.t.util.NoStacktrace is removed. Use scala.util.control.NoStackTrace instead. RB_ID=833188
util-core: Add Future.joinWith that also accepts a function (A, B) => C for mapping a joined result. RB_ID=838169
util-core: Add Future.by(Time), complementary to the existing Future.within(Duration) RB_ID=838169
util-core: Add c.t.util.ProxyTimer which allows for creating proxy based Timers outside of the com.twitter.util package. RB_ID=846194
🔀 util-core: Add AsyncStream.merge merge potentially inifite streams RB_ID=846681
🔒 util-security: Added new project. RB_ID=843070

💥 Breaking API Changes


* 🏗 Builds are now only for Java 8 and Scala 2.11. See the
  `blog post <https://finagle.github.io/blog/2016/04/20/scala-210-and-java7/>`_
  for details. ``RB_ID=828898``

* 🚚 util-core: `c.t.u.Bijection` is removed. use `c.t.bijection.Bijection`
  (https://github.com/twitter/bijection) instead. ``RB_ID=834383``

* 🚚 util-core: Deprecated method `Future.get()` has been removed because it made it
  too easy to hide blocking code. Replaced usage with the more explicit
  `com.twitter.util.Await.result(Future)`. ``RB_ID=833579``

* 🚚 util-core: Deprecated method `Future.get(Duration): Try` has been removed because it
  made it too easy to hide blocking code. Replaced usage with the more explicit
  `com.twitter.util.Await.result(Future.liftToTry)`. ``RB_ID=836066``

* 🗄 util-core: Deprecated methods `Future.isReturn` and `Future.isThrow` have been
  removed because they made it too easy to hide blocking code. Replaced usage with
  the more explicit `Await.result(Future.liftToTry).isReturn` and
  `Await.result(Future.liftToTry).isThrow`. ``RB_ID=837329``

* 👕 util-lint: Added methods `com.twitter.util.lint.Rules.removeById(String)` and
  `com.twitter.util.lint.RulesImpl.removeById(String)` so that it is now possible
  to remove a `com.twitter.util.lint.Rule` from the `com.twitter.util.lint.GlobalRules`
  set. ``RB_ID=840753``

🐛 Bug Fixes

util-core: AsyncMeter had a bug where if the burst size was smaller than the number of disbursed tokens, it would discard all of the tokens over the disbursal limit. Changed to instead process tokens in the wait queue with leftover tokens. This improves behavior where the actual period is smaller than can actually be simulated with the given timer. RB_ID=836742
util-core: Once didn't actually provide the guarantee it tried to, because of an issue with the scala compiler, https://issues.scala-lang.org/browse/SI-9814. It should now actually be synchronized. RB_ID=842245
🚀 util-zk: Fixed race when an existing permit is released between the time the list was gotten and the data was checked. RB_ID=835856
util-core: Memoize apply now throws IllegalStateException if a thread re-enters with identical input parameters instead of deadlocking.
