Minecraft Forge 3.3.7 Changelog:
============================================================================
Updated to FML #133

MAJOR: Droped ModLoader as a dependancy, ModLoader functionality is bundled with FML now, which is bundled with Forge. You only need to install Forge, nothing else.
  For the end-user, this means you need to install nothing else into your minecraft.jar
  For MCP coders, this means both minecraft.jar and minecraft_server.jar need to be 100% clean.

MAJOR: Built in support for HD textures up to 128x via Forge ModLoader. For more features, or higher resolutions, use Optifine

BugFix: Added missing disconnect reson to disconnect event.
BugFix: Fixed AStyle descrepancies between Linux and Windows that could cause patch files to fuxx
BugFix: All distrabutions now come with all associated license files.
BugFix: Fixed getCartClassForItem/getCartTypeFromItem returning null improperly.

Misc: Cleaned up render related hooks for Optifine compatibility

New: Added logo file and information on Forge for FML's Mod List page.
New: Bundled CodecIBMX from PaulsCode, and related license info. To support AudioMod functionality by default.
New: Leafe/tree hooks to allow modders more control over tree related world generation.
New: Ore generation hook for moders to play nicer with generating ores.
New: All Item/Blocks are now ITextureProviders, and have associated functions, to help modders have cleaner code.
New: New Ore Dictionary recipies, to allow modders simpler access to ore dictionary, and simpler usage on the end user's side. Allows for mix and match of ores in the same recipe. 
  IOreHandler should be used in only special cases from now on.

quite possibly the worst update for forge ever.  Why?  Because it made my brain explode.  CURSE YOU FORGE AND YOUR BRAIN EXPLODING POWER!

how do i install this with mcpatcher?

AND do i have to remove all my mods first?

1) Dont install using MCPatcher

2) Check for conflicting mods, for most cases, Forge will be the only mod in the jar.

3) Post support questions in the support forums, not in the release thread.

This thread is for things related to this release.

Where can i get older releases? Like 1.4.1 build 61?

here: http://lexmanos.no-ip.org:8080/job/Forge/.

Does this mean, all I required is Forge in my Minecraft in order to work. Modloader does not required even though there are others mod which is relying on it now?

As of version 3.3 yes.
