Changelog

v1.18.48 (September 1st, 2026)

• BREAKING CHANGE/BUGFIX: @Builder(builderClassName = "Builder") now generates an error, because the type names collide. #3857 (found after release)
• PLATFORM: JDK27 support added #4072.
• BUGFIX: @SneakyThrows usage on JDK26 no longer results in class files that require lombok.jar to be on the runtime classpath (which should not be neccessary). #4040.
• FEATURE: New config key lombok.checkReturnValueAnnotation (values: none, lombok; default: none) lets lombok generate @lombok.CheckReturnValue on generated methods where the return value should not be ignored, such as @With methods and @Builder.build(). A future lombok release may flip the default to lombok. #4013.
• PROMOTION: @SuperBuilder has been promoted to the main package. Otherwise, no changes have been made to the annotation. The old experimental annotation will remain for a few versions, at which point it will be marked as a deprecated annotation. Eventually it'll be removed. If you had lombok.config configuration for this annotation, the configuration keys for this feature have been renamed. #2209.
• OLD-CRUFT: lombok.experimental.Wither and lombok.Delegate are deprecated remnants; these features were moved (to respectively lombok.With and lombok.experimental.Delegate over 5 years ago. They are now removed entirely. If your project is dependent on an older version of lombok which still has those; fret not, lombok still processes these annotations. It just no longer includes them in the jar.
• FEATURE: CheckerFramework: Lombok now adds @SideEffectFree to constructors it makes if you have enabled checker framework via lombok.config.
• BUGFIX: CheckerFramework: Lombok would add @SideEffectFree to the build() method of any generated builder, even if it is a builder for invoking a method; in that case, the side-effect-free nature of build() mirrors the side-effect-free nature of the method invocation you've built. Lombok now checks if the method it generated a builder for is side effect free / 'check return type'.

Apache Commons Codec 1.23.0 Release Notes

The Apache Commons Codec team is pleased to announce the release of Apache Commons Codec 1.23.0.

The Apache Commons Codec component contains encoders and decoders for formats such as Base16, Base32, Base64, digest, and Hexadecimal. In addition to these widely used encoders and decoders, the codec package also maintains a collection of phonetic encoding utilities.

This is a feature and maintenance release. Java 8 or later is required.

New features

•         Add and use PhoneticEngine.Builder and deprecate old constructors. Thanks to Gary Gregory.
  

•         Add BeiderMorseEncoder.Builder and deprecate old constructor. Thanks to Gary Gregory.
  

•         Add PhoneticEngine.Builder.setMaxInputLength(int). Thanks to Yu Bao, Gary Gregory.
  

•         Add Base45 support. Thanks to Gary Gregory.
  

•         Add URLCodec.decodeUrl(BitSet, byte[]) to decode with a custom safe set. Thanks to Gary Gregory.
  

Fixed Bugs

•         GitIdentifiers orders tree entries by unsigned UTF-8 bytes, as Git does, instead of UTF-16 code units. Thanks to Jeff Lenamon.
  

•         Optimize PhoneticEngine.encode(String, LanguageSet) for speed. Thanks to Yu Bao, Gary Gregory.
  

•         RFC1522Codec.decodeText(String) now throws a DecoderException instead of a StringIndexOutOfBoundsException when a separator is missing. Thanks to Yu Bao, Gary Gregory.
  

•         Optimize Base58.convertFromBase58(byte[], Context) for speed and temporary object allocation. Thanks to Yu Bao, Gary Gregory.
  

•         Allocate a single MessageDigest and use it in Sha2Crypt.sha2Crypt(byte[], String, String, int, String). Thanks to Yu Bao, Gary Gregory.
  

•         Javadoc improvements. Thanks to Gary Gregory.
  

•         Throw IOException instead of IllegalArgumentException in BaseNCodecOutputStream and BaseNCodecOutputStream IO methods. Thanks to Gary Gregory.
  

•         Throw DecoderException instead of IllegalArgumentException in RFC1522Codec.decodeText(String). Thanks to Gary Gregory.
  

•         Fix Blake3 KDF example and clarify finalization semantics. Thanks to Gary Gregory.
  

•         Base32 and Base64 STRICT decoding now require the encoder's canonical alphabet, padding, and line separators, and validate streams through EOF. Use LENIENT to retain permissive decoding. Thanks to Gary Gregory.
  

•         Limit Base58 decoding to 8192 encoded bytes by default, checking cumulative stream input before buffering. Use Base58.Builder.setMaxDecodeLength(int) for larger trusted input. Encoding defaults to a configurable 8192-byte binary input limit through Base58.Builder.setMaxEncodeLength(int). Thanks to Gary Gregory.
  

•         Grow Base58 accumulation buffers geometrically within the configured input limits and validate actual accumulated length. Thanks to Gary Gregory.
  

•         Implement Base58 encoded-length calculation and explicitly reject unsupported line chunking. Thanks to Gary Gregory.
  

•         Close the underlying BaseNCodecOutputStream output even when final conversion or flushing fails, preserving suppressed close exceptions. Thanks to Gary Gregory.
  

•         Reject invalid GitIdentifiers tree entry names and file/directory name conflicts to prevent ambiguous tree serialization and colliding identifiers. Thanks to Gary Gregory.
  

•         Hex decoding now accepts only ASCII hexadecimal characters (0-9, A-F, a-f). Previously accepted non-ASCII Unicode digits and fullwidth letters now cause DecoderException, including when supplied as UTF-8 bytes or ByteBuffers. Thanks to Gary Gregory.
  

•         Restrict Hex decoding to ASCII hexadecimal characters. Thanks to Gary Gregory.
  

•         Validate BinaryCodec input while preserving leading-bit truncation. Thanks to Gary Gregory.
  

•         Reject oversized Beider-Morse input before language guessing. Thanks to Gary Gregory.
  

•         QuotedPrintableCodec decoding now preserves hard CRLF line breaks and, leniently, unpaired CR and LF bytes instead of discarding them. Soft line breaks require the full =CRLF sequence; previously accepted =CR without LF now throws DecoderException. This affects both constructor modes and QCodec, which shares the decoder. Thanks to Gary Gregory.
  

•         Bound Sha2Crypt rounds from caller-supplied salts. Thanks to Gary Gregory.
  

•         Bound Sha2Crypt password length to prevent quadratic CPU DoS. Thanks to Gary Gregory.
  

•         Make the @param names in BaseNCodec match the parameters they document ([#444](https://github.com/apache/commons-codec/issues/444)). Thanks to geonseok, Gary Gregory.
  

• CODEC-345: Restore URLCodec.encodeUrl(BitSet, byte[]) support for custom safe sets containing percent and plus, and document the decoding limitations. Thanks to Ganesh Gautam, Gary Gregory.
• CODEC-245: Reject malformed Sha2Crypt salt syntax (#445). Thanks to Efe, Gary Gregory.

Updates ch.qos.logback:logback-core from 1.6.3 to 1.6.5

Release notes

Sourced from ch.qos.logback:logback-core's releases.

Logback 1.6.5

2026-09-30 Release of logback version 1.6.5

• Fixed a vulnerability CVE-2026-104721 closely related to CVE-2026-19880. The fix in version 1.6.3, which strips forward and backward slashes from MDC values, was insufficient. An MDC value could still contain relative path components such as .., variable references such as /, or characters that are special in file name patterns and email addresses. This latest vulnerability was found and reported by François Martin (GitHub: @​martinfrancois, https://github.com/martinfrancois).

MDCBasedDiscriminator, used by SiftingAppender, now rejects MDC values instead of stripping characters from them. An MDC value is rejected if it is empty, if it is longer than 64 characters, if it contains the sequence .., or if it contains any of the following characters: / \ $ { } [ ] ( ) | ? * + % , @. When an MDC value is rejected, the discriminator returns the value of its DefaultValue property. A warning is emitted for each rejected value. These warnings are rate-limited.

• When compression is enabled, TimeBasedRollingPolicy and SizeAndTimeBasedRollingPolicy now also remove old log files that were never compressed, for example because the application was not running at rollover time. Previously, such files were ignored by maxHistory and accumulated indefinitely. This issue was discussed in discussions/1032. See TimeBasedRollingPolicy.

• SimpleInvocationGate, deprecated in version 1.6.3, is now marked for removal. Use FixedIntervalInvocationGate instead.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit d1b829dcdb9fd98511c64401beb1419a9c9384aa associated with the tag v_1.6.5. The release was built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.6.4

2026-09-24 Release of logback version 1.6.4

• Variable substitution is again applied to the scan attribute of the <configuration> element. The scanning refactoring in version 1.5.27 had dropped substitution, so values such as ${logback.scan.enabled:-true} were no longer resolved. As before version 1.5.27, an unrecognized non-empty value turns scanning on. The same substitution now applies to the scan attribute of <propertiesConfigurator>. This regression was reported in issues/1065 by vaibhavjain2.

• OutputStreamAppender and FileAppender now handle stateful encoders. The Encoder interface has a new default method called isStateful(), which returns false. An encoder that keeps state between calls to encode() can return true. For such encoders, the appender holds its write lock while encoding and while writing, so the output of concurrent appends cannot interleave. Stateless encoders still encode outside the lock, so their performance does not change. Existing encoders need no changes.

• Several race conditions in OutputStreamAppender and FileAppender were fixed. The appender is now marked started and the encoder header is written while the same lock is held, so a concurrent append can no longer write an event before the header. After acquiring the lock, the appender checks again whether it has been stopped, so no event is written after the footer. In prudent mode, FileAppender now encodes and writes each event while holding the lock.

• Fixed a data race on the logger count in LoggerContext. Loggers are created under the lock of their parent logger, so loggers with different parents could be created at the same time and increments of the shared counter could be lost. As a result, LoggerContext.size() could return a value lower than the actual number of loggers. The counter is now an AtomicInteger. This issue was reported in issues/1038 by hcantunc. The fix was contributed in PR #1055 by seonwoo_jung.

• TimeBasedRollingPolicy now supports half-day periods. Date patterns with the AM/PM marker, for example %d{yyyy-MM-dd-a}, used to be detected as daily and rolled over only at midnight. They now roll over at both 00:00 and 12:00. This issue was reported in issues/976 by shakthifuture. The fix was contributed in PR #1051 by seonwoo_jung. See TimeBasedRollingPolicy.

• If org.jline.jansi.AnsiConsole cannot be found on the class path, JansiConsoleAppender now emits warnings that explain how to add org.jline:jansi-core and then writes to the plain console stream. See codes.html#missingJlineJansi.

• The unused ch.qos.logback.classic.util.LogbackMDCAdapterSimple class was removed. LogbackMDCAdapter remains the default MDC adapter.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit 07d291ca0d280bc5da934ec9ff5f1da634fd7937 associated with the tag v_1.6.4. The release was built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.
