-"Error handling modernization" (in progress)
+v1.11.0 - 2025-11-15
 
-- Introduced typed, wrapped errors via certlib/certerr.Error (Source, Kind, Op, Err) with Unwrap.
+Added
-- Standardized helper constructors: DecodeError, ParsingError, VerifyError, LoadingError.
+- cache/mru: introduce MRU cache implementation with timestamp utilities.
-- Preserved sentinel errors (e.g., ErrEncryptedPrivateKey, ErrInvalidPEMType, ErrEmptyCertificate) for errors.Is.
-- Refactored certlib to use certerr in key paths (CSR parsing/verification, PEM cert pool, certificate read/load).
-- Migrated logging/file.go and cmd/kgz away from github.com/pkg/errors to stdlib wrapping.
-- Removed dependency on github.com/pkg/errors; ran go mod tidy.
-- Added package docs for certerr and a README section on error handling and matching.

-- Run golangci-lint (errorlint, errcheck) and address findings.
