Golang 1.13
Fedora 31 provides Golang version 1.13, up from version 1.12 in Fedora 30.
By setting GOSUMDB=off
and GOPROXY=direct
environment variables, Fedora slightly diverged from the Golang upstream default configuration. This change preserves the ability of users to set the environment variables to value they desire and prevents unintended leaks of personal information. There is no impact on users of the compiler.
Notable changes include:
Nuevas Características
-
Version 1.13 supports more uniform and modernized set of number literal prefixes.
-
The new
GOSUMDB
environment variable has been added. It identifies the name, and optionally the public key and server URL of the checksum database. This is done in order to consult the checksums of modules which are not yet listed in thego.sum
file of the main module. -
The
go
command verifies the mapping between pseudo-versions and version-control metadata. -
The
go env
command accepts a-w
flag to set the per-user default value. A-u
flag unsets the previously-set default. The defaults set throughgo env -w
command are stored in thego/env
file within theos.UserConfigDir()
function. -
The assembler supports many of the atomic instructions introduced in ARM v8.1.
-
The Transport Layer Security (TLS) 1.3 protocol is supported in the
crypto/tls
package by default. -
Version 1.13 supports error wrapping.
Deprecations
-
Version 1.13 is the last one that runs on the Native Client (NaCl) sandboxing technology.
-
The
go -get
subcommand no longer supports the-m
flag. -
As of version 1.13, the
godoc
webserver is not included in the main binary distribution.
