Beware this release has introduced a new public API and its semver is therefore incorrect. Code quality: use go 1.15 in travis use magefile as task runner Fixes: small fixes about new go 1.13 error formatting system Fix for long time race condiction with mutating data hooks Features: build support for zos Fixes: the dependency toward a windows terminal library has been removed Features: a new buffer pool management API has been added a set of `<LogLevel>Fn()` functions have been added Fixes: end of line cleanup revert the entry concurrency bug fix whic leads to deadlock under some circumstances update dependency on go-windows-terminal-sequences to fix a crash with go 1.14 Features: add an option to the `TextFormatter` to completely disable fields quoting Code quality: add golangci linter run on travis Fixes: add mutex for hooks concurrent access on `Entry` data caller function field for go1.14 fix build issue for gopherjs target Feature: add an hooks/writer sub-package whose goal is to split output on different stream depending on the trace level add a `DisableHTMLEscape` option in the `JSONFormatter` add `ForceQuote` and `PadLevelText` options in the `TextFormatter` Fixes build break for plan9, nacl, solaris This new release introduces: Enhance TextFormatter to not print caller information when they are empty (#944) Remove dependency on golang.org/x/crypto (#932, #943) Fixes: Fix Entry.WithContext method to return a copy of the initial entry (#941) This new release introduces: Add `DeferExitHandler`, similar to `RegisterExitHandler` but prepending the handler to the list of handlers (semantically like `defer`) (#848).
