Logback 1.6.3

2026-08-14 Release of logback version 1.6.3

• In response CVE-2026-19880, MDCBasedDiscriminator (used by SiftingAppender) now strips forward and backward slashes (/, \) from MDC values before they are used as discriminating keys. This prevents path segments from escaping into destinations controlled by an attacker. When sanitisation actually changes a value, a warning is emitted; the warning is rate-limited (a small batch, then a lull of about ten minutes).

• Colour console support is split out into a dedicated JansiConsoleAppender. It wraps stdout or stderr with Jansi so ANSI escape sequences (for example coloured patterns) render correctly on terminals that need it, notably Windows. Prefer this class over the older path described next. See the appenders documentation.

• The withJansi property on ConsoleAppender is deprecated. Existing configurations that still set <withJansi>true</withJansi> continue to work for compatibility, but new setups should use JansiConsoleAppender instead.

• ConsoleAppender no longer treats the process console as an exclusive resource: stopping it does not close System.out / System.err. JansiConsoleAppender pairs each AnsiConsole.systemInstall() with systemUninstall() on stop, so repeated start/stop cycles do not leave Jansi installed or tear down streams shared with the rest of the JVM. Related behavior is covered by tests for issues/1063.

• Invocation throttling helpers were reworked: SimpleInvocationGate is renamed FixedIntervalInvocationGate, and BatchedFixedIntervalInvocationGate allows a short burst of invocations before applying a fixed lull. The sanitisation warning above uses the batched gate.

• The JPMS module-info for logback-core now exports the ch.qos.logback.core.property package, which had been missing from the module descriptor.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit e8e824dede022a6d7208b36cfa875b0d1b7772f3 associated with the tag v_1.6.3. The release was built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.6.2

clean.full.1.6.2.mp4

2026-08-10 Release of logback version 1.6.2

• Configuration analysis now detects contradictory caller-data inclusion instructions. For example, an AsyncAppender, SocketAppender or SMTPAppender with includeCallerData left at the default false is incompatible with a layout or encoder pattern that uses a caller-data converter such as %C, %M, %L, %F, %l or %caller. At runtime those converters would print question marks and still incur extraction cost on a worker thread. Logback now emits a configuration-time warning when such instructions disagree. See codes.html#callerContradiction for details. This issue was reported in issues/1059 by leeychee. The initial analysis was contributed by seonwoo_jung.

• Caller-contradiction analysis can be turned off by setting the logback.skipCallerContradictionAnalysis variable to true, either as a system property (-Dlogback.skipCallerContradictionAnalysis=true) or as a property in the configuration file:

  <property name="logback.skipCallerContradictionAnalysis" value="true"/>

• SimpleSocketServer and SimpleSSLSocketServer now require an explicit client IP whitelist. On the command line, pass one or more allowed addresses (single IPs or CIDR ranges) after the configuration file. An empty whitelist means no clients are accepted. When embedding the server programmatically, register allowed addresses with addAllowedClientAddress(String) or setAllowedClientAddresses(Collection) before clients connect. See the documentation on restricting client access.

• Added ThrowableProxyVOBuilder for assembling a ThrowableProxyVO field by field, with a corresponding ThrowableProxyVO.builder() entry point.

• Dependency analysis handlers now run their postHandle method after child models have been processed, so checks that depend on nested appenders (such as caller-contradiction analysis) see a complete picture.

• Updated several dependencies, including Angus Mail to 2.0.4 and Jetty (test) to 12.1.12.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit e3d78330ad1ba024fd987fd00c3ffb9cfcdb07dc associated with the tag v_1.6.2. The release was built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.6.1

2026-07-28 Release of logback version 1.6.1

• In TimeBasedRollingPolicy, when the file option is set, the intermediate file renamed before asynchronous compression now receives the target archive name without the compression suffix (e.g. .gz, .zip, .xz). Previously it used a nanotime-based .tmp suffix. This makes the file easier to identify if compression fails during rollover. (See also the following paragraph.)

• On GZ, ZIP, or XZ compression failure, the original (uncompressed) log file is no longer deleted. Compression strategies now delete the source file only after successful compression and emit a warning that the original was left intact.

• ConsoleAppender with now probes JLine's org.jline.jansi.AnsiConsole first and falls back to the legacy FuseSource org.fusesource.jansi.AnsiConsole class. This keeps ANSI coloring working after Jansi moved under the JLine project. The optional org.jline:jansi-core artifact is declared as a dependency alongside the existing FuseSource jansi dependency. A preferredJansiClassName property was added for tests. This issue was reported in issues/1043 by seonwoo_jung who also provided the relevant PR.

Strengthened the logging regression contract for this dependency update. The test now verifies the active SLF4J provider is Logback, INFO/ERROR events are emitted exactly once with the expected level/logger/message formatting, and throwable type/message plus stack trace survive. @codex review
