Emacs 31.1 has been released with incremental usability, completion, window-management and terminal improvements rather than a single flagship feature. The release permanently removes the legacy unexec dumper, deprecated since Emacs 27, leaving the portable dumper as the supported mechanism for preloading Emacs Lisp state. It also stops building and installing Emacs’s old ctags program, directing users to Universal Ctags or to `etags --ctags` for compatible behavior. A planned new garbage collector was postponed to Emacs 32. A new User Lisp Directory feature automatically processes Lisp files under `user-lisp/` in an Emacs configuration directory, including recursive byte compilation, autoload generation and load-path setup. Tree-sitter modes can now offer to install their required language grammars. Completion gains configurable eager display and live updating of the *Completions* buffer, while the rewritten flex completion style is intended to be faster and rank matches more accurately. New commands rotate, flip and transpose window layouts, and a setting controls preferred split direction. Compatible terminals now enable `xterm-mouse-mode` by default, and TTY frames gain child-frame support. Emacs 31.1 also adds built-in controls for collapsing minor-mode indicators, hiding a buffer’s mode line, extending selections with Shift-click, and preventing asynchronous native compilation on battery power. It includes Org 9.8 and supports Unicode Standard 17.0.

The Go team released Go 1.27, adding language features, toolchain updates, runtime profiling, performance work, and new standard-library packages. The release supports generic methods, allowing methods such as math/rand/v2.Rand.N to work across integer types. Struct literals can now initialize nested or embedded fields through valid field selectors, and generalized function type inference now covers all assignment contexts, including composite literals, type conversions, and channel sends. Go 1.27 adds go fix modernizers for atomic types, embedded literals, backward slices, and unsafe functions. The go doc command supports package@version queries, while go mod tidy consolidates multiple require blocks into direct and indirect blocks. Size-specialized allocation reduces costs for objects smaller than 80 bytes by up to 30%, with roughly 1% overall improvement claimed for allocation-heavy programs. The runtime/pprof goroutineleak profile is generally available for detecting permanently blocked goroutines. Standard-library additions include encoding/json/v2, post-quantum ML-DSA signatures through crypto/mldsa, UUID support, experimental SIMD packages, and an in-memory HTTP test server for testing/synctest.
