v0.6.0

Added

• discordWebhook config key — when set, DPM posts a summary notification to the specified Discord channel after each /dpm update run (with per-plugin version diffs) and on any download failure from /dpm get (#83)
• DiscordNotificationService — sends optional Discord webhook notifications; exceptions are silently swallowed so a failed webhook never affects the command result (#83)
• Single retry with a 2-second delay on transient network failures: GitHubReleaseService.doFetch() retries once on IOException or 5xx responses; DownloadService.openNetworkStream() retries once on IOException; 4xx responses are not retried (#85)
• Logger.warn() — always prints to the console regardless of debugMode, used for operator-visible error messages (#80)
• Server-console audit trail: plugin.getLogger().info() is emitted on success and .warning() on failure for /dpm get, /dpm update, /dpm remove, and /dpm clean --confirm (#81, #87)

Fixed

• VersionStore now uses the injected dansplugins.dpm.utils.Logger instead of a static JUL logger; load and save failures emit a clearly prefixed warning that always appears in the server console (#82)
• GitHub rate-limit responses (HTTP 429 and HTTP 403 with X-RateLimit-Remaining: 0) now produce a specific warning advising to configure a githubToken; previously they were logged as generic API errors (#79)
• GitHub API authentication failures (HTTP 401) now produce a specific warning identifying the token as the cause; previously folded into the generic non-200 path (#88)
• Network errors, JAR download failures, and missing .jar releases now use Logger.warn() so they always appear in the server console, even when debugMode is off (#80)
• JAR download stream now sets a 10 s connect timeout and 30 s read timeout; previously URL.openStream() had no timeout, so a hung CDN would stall the async task indefinitely
• Conflicting JARs (e.g. Plugin-1.0.0.jar) are now removed only after a successful download; previously they were deleted before the network call, silently uninstalling the plugin on any download failure
• JAR write buffer increased from 1 KiB to 8 KiB, reducing I/O cycles for large plugin files

Removed

• Multi-line Javadoc blocks from HelpCommand, DansPluginManager, Logger, and TabCompleter (CLAUDE.md violation)

Changed

• /dpm stats now shows available plugin count (registered minus installed) as a third stat line
• /dpm list available now appends each plugin's description after its name, separated by an em-dash
• /dpm remove <plugin-name> --confirm now prints a reinstall hint (/dpm get <name>) after the removal success message
• /dpm update success message now shows the old and new version tag (e.g. v4.5.0 → v4.6.3) when a plugin was previously tagged; shows only the new tag if no prior tag was stored
• All "Plugin not found" errors across /dpm get, /dpm update, /dpm info, and /dpm remove now append Use /dpm search <keyword> to find the right name.
• /dpm remove preview and confirm paths now warn when other installed plugins declare a hard dependency on the plugin being removed
• Download failures now distinguish between network errors (GitHub unreachable) and file write errors (plugins folder not writable), surfacing a specific hint in each case
