we are happy to announce Akka Http 10.1.0, the first release of the 10.1.x series.
The most important changes are:
- The new client pool implementation introduced in 10.0.11 is now the default. We have identified and fixed several
bugs in the RC period so by now we are quite confident that the new client pool will be a solid replacement for the
- Documentation has been completely consolidated between Scala and Java pages. Hundreds of directive
documentation pages have been merged in a tireless effort by @jonas,
@jlprat, and Akka team’s @raboof. The overall
documentation structure has been improved.
- Experimental artifacts are available for Scala 2.13.0-M3.
- Support for Akka 2.4.x, which is at its end-of-life with the end of 2017, has been removed. In the future, this will allow us
to make use of features that only Akka 2.5 supports.
- Methods deprecated during the life-time of Akka HTTP 10.0.x have been removed. Methods just deprecated for 10.0.11
have not yet been removed to allow for a smooth transition.
New client pool implementation is now the default
The new client pool implementation introduced in 10.0.11 is now the default. Since 10.0.11, we fixed several bugs in the
new client pool implementation.
You can still fall back to the old implementation by setting
akka.http.host-connection-pool.pool-implementation = legacy.
Akka is not an explicit dependency anymore / Removal of Akka 2.4 support
Akka HTTP 10.0.x has always supported Akka 2.5, while allowing users to still remain on Akka 2.4.x if they choose to do so.
By now Akka 2.4 has reached its end of life. Therefore, Akka HTTP 10.1.x only supports Akka >= 2.5.11
(and future versions during the life of Akka HTTP 10.1.x) so we will be able to make of features only provided by Akka 2.5.
In some cases we bump the minimum supported patch version of Akka to be able to use new features quickly.
Using Akka HTTP with Akka 2.5 used to be
a bit confusing, because Akka HTTP explicitly depended on Akka 2.4. Trying to use it together with Akka 2.5,
running an Akka HTTP application could fail with class loading issues if you forgot to add a dependency to
akka-stream of the same version. For that reason, we changed the policy not to depend on
explicitly anymore but mark it as a
provided dependency in our build. That means that you will always have to add
a manual dependency to
akka-stream (veterans may remember this policy from Spray).
Please make sure you have chosen and added a dependency to
akka-stream when updating to the new version.
Currently, the right dependency to add is
libraryDependencies += "com.typesafe.akka" %% "akka-stream" % "2.5.11"
Support for Scala 2.13.0-M3
Akka HTTP 10.1.0 is released for Scala 2.11, 2.12, and 2.13.0-M3. Due to a regression in Scala 2.13.0-M3
tail call optimization does not apply anymore in some cases where it did before which might lead to stack overflow when
running with Scala 2.13.0-M3.
Methods were removed that have been deprecated during the life-time of Akka HTTP 10.0.x. Methods that were only deprecated
in the last release of Akka HTTP, 10.0.11, are not yet removed to allow for a smooth transition. In general, our guarantee
for minor release updates is that code that compiled on the latest version of the previous minor release (10.0.11 in this case)
should be both source and binary compatible with the latest version of the current minor release. We might make
exceptions to the rule for cases where the maintenance burden seems greater than the risk of breaking major users / third-party
libraries. We’ll treat any other binary incompatibilities as regressions.
As the compatibility notes explain in detail, we guarantee binary compatibility. In
some cases, however, a new version is not strictly source compatible. We try to limit the impact of these kinds
of changes but sometimes, they are inevitable to improve the API.
Source incompatible changes are:
- Removed deprecated methods from 10.0.x
ServerBinding.unbindreturn type has been changed to
Removal of OSGi support
Supporting OSGi is error prone and high maintenance and it repeatably broke, blocked releases, or metadata turned out to
be wrong. As we are no experts in OSGi, and are nowadays focusing our efforts on JDK9+ jigsaw compatibility
we had to remove OSGi support for now. If you care about OSGi support please step up and help out. Most important
would be adding tests that verify that the OSGi infrastructure does not break the build and the metadata actually works
at runtime. See #1852 for more information.
