Software Update: Go 1.15.4 / 1.14.11

Go, also referred to as golang, is a programming language developed by Google and the open source community since 2007. Among other things, the language is cloudflare, google, Netflix and Uber used. Go code can be compiled for Android, Linux, macOS, FreeBSD, and Windows, on i386, amd64, and ARM processor architectures. The syntax of Go is similar to that of C and similar programming languages, although there are also some notable differences. Go also offers the option of distributed programming, where several processes are executed simultaneously. The team has released Go versions 1.15.4 and 1.14.11 with the following changes:

Version 1.15.4

• cmd/compile, runtime, reflect: pointers to go:notinheap types must be stored indirectly in interfaces [1.15 backport]
• cmd/cgo: opaque struct pointers are broken since Go 1.15.3 [1.15 backport]
• time: Location interprets wrong timezone (DST) with slim zoneinfo [1.15 backport]
• x/net/http2: the first write error on a connection will cause all subsequent write requests to fail blindly [1.15 backport]
• net/http: request.Clone doesn’t deep copy TransferEncoding [1.15 backport]
• runtime: macOS syscall.Exec can get SIGILL due to preemption signal [1.15 backport]
• compress/flate: deflatefast produces corrupted output [1.15 backport]
• x/net/http2: connection-level flow control not returned if stream errors, causes server hang [1.15 backport]
• cmd/link: sectionForAddress(0xA9D67F) address not in any section file [1.15 backport]

Version 1.14.11

• time: Location interprets wrong timezone (DST) with slim zoneinfo [1.14 backport]
• x/net/http2: the first write error on a connection will cause all subsequent write requests to fail blindly [1.14 backport]
• runtime: macOS-only segfault on 1.14+ with “split stack overflow” [1.14 backport]
• net/http: request.Clone doesn’t deep copy TransferEncoding [1.14 backport]
• runtime: macOS syscall.Exec can get SIGILL due to preemption signal [1.14 backport]
• x/net/http2: connection-level flow control not returned if stream errors, causes server hang [1.14 backport]
