79+ Google's Java client libraries,
80+ [ Google Cloud Client Libraries] [ cloudlibs ]
81+ and
82+ [ Google Cloud API Libraries] [ apilibs ] ,
83+ follow the
84+ [ Oracle Java SE support roadmap] [ oracle ]
85+ (see the Oracle Java SE Product Releases section).
86+
87+ ### For new development
88+
89+ In general, new feature development occurs with support for the lowest Java
90+ LTS version covered by Oracle's Premier Support (which typically lasts 5 years
91+ from initial General Availability). If the minimum required JVM for a given
92+ library is changed, it is accompanied by a [ semver] [ semver ] major release.
93+
94+ Java 11 and (in September 2021) Java 17 are the best choices for new
95+ development.
96+
97+ ### Keeping production systems current
98+
99+ Google tests its client libraries with all current LTS versions covered by
100+ Oracle's Extended Support (which typically lasts 8 years from initial
101+ General Availability).
102+
103+ #### Legacy support
104+
105+ Google's client libraries support legacy versions of Java runtimes with long
106+ term stable libraries that don't receive feature updates on a best efforts basis
107+ as it may not be possible to backport all patches.
108+
109+ Google provides updates on a best efforts basis to apps that continue to use
110+ Java 7, though apps might need to upgrade to current versions of the library
111+ that supports their JVM.
112+
113+ #### Where to find specific information
114+
115+ The latest versions and the supported Java versions are identified on
116+ the individual GitHub repository ` github.com/GoogleAPIs/java-SERVICENAME `
117+ and on [ google-cloud-java] [ g-c-j ] .
