Adding a lock on a composite build is done the same way it is done for a regular build: it can be done by adding the Shared Resources build feature.
Other improvements
- Browsing of artifacts inside archives is now supported for all external artifacts storages too (previously this feature was available only if artifacts were stored in the internal artifacts storage)
Java 9 and Java 10 can now be used to run an agent
- Gerrit Commit Status Publisher now allows an admin to configure custom values for success and failure instead of +1 and -1 respectively. This label is also configurable.
- Build chains page has got new grouping option: it groups together in a single node all of the build configurations which are not related to the current context
- All fixed issues
