🎯 Overview

Version 3.1.0 is a major feature release combining five significant improvements focusing on user configuration flexibility, bug fixes, and advanced filtering capabilities.

📦 What's New

1. 🔧 MOVE_URL_TO_END Configuration

Type: Feature Enhancement
Impact: URL Positioning Control

What Changed:

  • Migrated URL positioning from hardcoded platform behavior to user-configurable setting
  • Added new MOVE_URL_TO_END setting in SETTINGS configuration
  • Users now have explicit control over URL repositioning behavior

Why It Matters:

  • Flexibility: Different users have different preferences for URL placement
  • Transparency: Explicit configuration instead of platform-dependent behavior
  • Control: Works consistently across all platforms (RSS, Twitter, Bluesky, YouTube)

Migration Required:

// Add to your SETTINGS if you want URL repositioning:
MOVE_URL_TO_END: true,  // Move first URL to end of content (default: false)

Before v3.1.0:

  • RSS feeds automatically moved URLs to end (hardcoded in platform config)
  • Users had no control over this behavior

After v3.1.0:

  • User explicitly enables/disables via MOVE_URL_TO_END setting
  • Works consistently across all platforms

2. 🎛️ Advanced NOT/COMPLEX Filtering

Type: Feature Enhancement
Impact: Content Filtering

What's New:
Enhanced filter rule system with NOT operations and complex logical combinations:

New Filter Types:

// NOT Filter - exclude content
{
  type: "not",
  rule: { type: "literal", pattern: "spam" }
}

// COMPLEX Filter - nested AND/OR/NOT combinations
{
  type: "complex",
  rules: [
    { type: "and", keywords: ["AI", "2025"] },
    { type: "not", keyword: "advertisement" }
  ]
}

Use Cases:

  • Quality Control: Require specific keywords while excluding spam
  • Smart Filtering: Complex boolean logic (AI AND 2025 AND NOT advertisement)
  • Flexible Rules: Nested combinations for precise content curation

3. 🚀 Unified Filter Structure

Type: Feature Enhancement
Impact: Advanced Multi-Dimensional Filtering

What's New:
Extended OR/AND/NOT filters with unified structure supporting multiple filter dimensions:

New Capabilities:

// Multi-dimensional filtering
{
  type: "or",  // or "and" or "not"
  content: ["keyword1", "keyword2"],           // Literal content matches
  contentRegex: ["\\bpattern\\b"],             // Regex content patterns
  username: ["@user1", "@user2"],              // Literal username matches
  usernameRegex: ["^@official", "bot$"],       // Regex username patterns
  domain: ["example.com", "news.org"],         // Literal domain matches
  domainRegex: ["bit\\.ly", "\\d{5,}\\."]     // Regex domain patterns
}

Key Features:

  • ✅ OR Filters: Match if ANY condition is true (content OR username OR domain)
  • ✅ AND Filters: Match only if ALL conditions are true
  • ✅ NOT Filters: Exclude if ANY condition matches
  • ✅ Regex Support: Pattern matching for content, usernames, and domains
  • ✅ 100% Backward Compatible: Legacy keywords array syntax still works

Example Use Cases:

News Bot Quality Filter:

PHRASES_REQUIRED: [
  {
    type: "and",
    content: ["breaking", "news"],
    usernameRegex: ["^@(bbc|cnn|reuters)"],
    domain: ["bbc.com", "cnn.com", "reuters.com"]
  }
]

Spam Prevention:

PHRASES_BANNED: [
  {
    type: "or",
    content: ["click here", "limited time"],
    contentRegex: ["\\d+%\\s+off"],
    domainRegex: ["bit\\.ly", "tinyurl"]
  }
]

Bot Filtering:

PHRASES_BANNED: [
  {
    type: "not",
    contentRegex: ["\\bRT\\s+@\\w+:", "\\[bot\\]"],
    usernameRegex: ["bot$", "^auto"]
  }
]

4. 🐛 FORCE_SHOW_ORIGIN_POSTURL Bug Fix

Type: Critical Bug Fix
Impact: URL Display Logic

Problem:
In v3.0.3, the FORCE_SHOW_ORIGIN_POSTURL setting was not properly respected in all code paths. Quote tweets would correctly use entryUrl, but non-quote tweets with this flag enabled would fall back to complex URL selection logic.

Root Cause:

// v3.0.3 (BUGGY):
if (isQuoteTweet) {
  urlToShow = entryUrl;
} else {
  urlToShow = contentHasUrl ? (hasImage ? imageUrl : entryUrl) : ...;
}

Solution:

// v3.1.0 (FIXED):
if (SETTINGS.FORCE_SHOW_ORIGIN_POSTURL || isQuoteTweet) {
  urlToShow = entryUrl;
} else {
  urlToShow = contentHasUrl ? (hasImage ? imageUrl : entryUrl) : ...;
}

Impact:

  • ✅ FORCE_SHOW_ORIGIN_POSTURL now works correctly in ALL scenarios
  • ✅ Consistent URL display behavior
  • ✅ No configuration changes needed (automatic fix)

5. 🔧 Anchor Tag Fix (HTML Processing)

Type: Critical Bug Fix
Impact: URL Extraction from HTML

Problem:
RSS feeds containing HTML anchor tags created duplicate and malformed URLs:

Input:

<a href="https://t.co/CSwiEUZe9Q">pic.twitter.com/CSwiEUZe9Q</a>

Old Output (BUGGY):

https://pic.https://twitter.com/CSwiEUZe9Q

What Caused This:

  1. HTML cleanup removed <a> tags but kept BOTH texts
  2. Domain fix added https:// to pic.twitter.com
  3. Result: duplicated/malformed URLs

Solution:
Added new anchor tag extraction BEFORE HTML cleanup:

// New regex pattern:
ANCHOR_TAG: /<a\s+[^>]*href=["']([^"']+)["'][^>]*>.*?<\/a>/gi

// Applied in normalizeHtml():
str = str.replace(REGEX_PATTERNS.ANCHOR_TAG, function(match, hrefUrl) {
  return hrefUrl || "";  // Keep only href URL, discard link text
});

New Output (FIXED):

V katedrále svatého Víta na Pražském hradě se v sobotu lidé 
naposledy rozloučili s kardinálem Dominikem Dukou.
https://x.com/CT24zive/status/1989694033896124710

Impact:

  • ✅ No duplicate URLs
  • ✅ No malformed URLs like https://pic.https://...
  • ✅ Clean content extraction from RSS feeds
  • ✅ Automatic fix, no configuration needed

🚀 Migration Guide

From v3.0.x to v3.1.0

1. URL Positioning (Optional)

Action Required: If you relied on automatic URL repositioning for RSS

Add to SETTINGS:

MOVE_URL_TO_END: true,  // Enable URL repositioning (default: false)

2. FORCE_SHOW_ORIGIN_POSTURL Fix

Action Required: None - automatic improvement

If you previously enabled this setting and it wasn't working consistently, it's now fixed.

3. Filter Enhancements (Optional)

Action Required: Only if you want to use new features

Legacy syntax still works:

// This continues to work exactly as before:
PHRASES_BANNED: [
  { type: "or", keywords: ["spam", "ad"] },
  { type: "and", keywords: ["AI", "2025"] }
]

New unified syntax (optional upgrade):

// Enhanced with regex and multi-dimensional filtering:
PHRASES_BANNED: [
  { 
    type: "or", 
    content: ["spam", "ad"],
    contentRegex: ["\\[bot\\]"],
    usernameRegex: ["bot$"]
  }
]

4. Anchor Tag Fix

Action Required: None - automatic fix

HTML anchor tags in RSS feeds now process correctly. No configuration changes needed.
