Care to be more specific? You have just listed over a decade of product versions. Might as well ask "tell me the birth of every windows feature since Windows 2000."  They are too numerous to list, Not to mention how many get deprecated. Does knowing that FRS is deprecated and will officially lose the last vestiges of support in six months really help the average 2008/2012 deployment that runs on DFS-R? Or the nuances of the dozen or so features that have been retired since NT4 dropped off the planet?

Lync (soon to be Skype for Business) is an expansive product with a very full history. It has hundreds of features and yes many features that have also been deprecated or changed over its 15 years of life (it started as an exchange adjunct even before LCS 2003), so covering all of that is simply not feasible. Even if I could track down release notes that old, cutting and pasting that much content would take up more space than this text field allows.

Office Communicator 2007 R2 is a unified communications application that helps end users be more productive by enabling them to communicate and collaborate easily with others in different locations or time zones using a range of different communication options, including instant messaging (IM), voice, desktop sharing and video. Integration with programs across the Microsoft Office system — including Word, Excel, PowerPoint, OneNote, Groove, and SharePoint — gives end users many different ways to communicate directly from the context of their task.
Office Communicator 2007 R2 offers all the features of the previous version, including presence information, instant messaging (IM), voice over Internet Protocol (VoIP), video, and desktop sharing. A number of new features have been added as well, including the ability to add more people to an existing audio-video conferencing session and share your desktop in order to collaborate, discuss, or edit documents with a single colleague or a whole team.
Office Communicator 2007 R2 integrates the various ways you communicate and provides one application to give you a rich and flexible experience every time.
•      Whether you prefer instant messaging, audio, or video, it is all available in one application. Start an instant messaging conversation with a colleague, invite more people to the conversation, switch to voice, and add video with simple one-click actions.
•      You can even forward calls to your team, set delegates, and reach your voice mail easily with rich VoIP capabilities.
•      Also, with the new desktop sharing capability, you can easily collaborate with your colleagues and team members without the costly overhead of organizing elaborate meetings.
•      Work from anywhere -Office Communicator 2007 R2 provides all of its capabilities from any location via a simple Internet connection. There is no need for a secure tunnel (VPN connection) to the corporate network. With security-enhanced VoIP, IM, and desktop sharing, it can be accessible whether you are in your office or traveling.
LYNC 2010 was introduced in year 2010
In addition to a new look, Lync 2010 has improved usability and new features that encourage communication and facilitate unplanned meetings and conversations among colleagues.
•      The Contacts list is enhanced with additional customization and search features.
•      The Conversations list displays a user’s current and recent conversations. If multiple conversations are in progress, the user can switch from one Conversation window to another by clicking a conversation in the list. Lync obtains conversation history from Microsoft Exchange Server and displays it in the Conversations list so that users can view and continue their past conversations.
•      Users can now easily see each other’s latest activities, such as office moves or new personal photos, or a history of the last several status notes that have been posted. Contacts can see each other’s’ updates if they are assigned a Family and Friends, Workgroup, Colleagues or External Contacts privacy relationship.
•      The Phone view contains a dial pad for making calls, a list of voice-mail messages, and a Check button for testing call quality.




Contacts enhancements
You now can see your contacts’ corporate or custom pictures for quick identification and change the way you display your contacts, such as by presence status or contact group.
Your Frequent Contacts are the 10 contacts you most frequently have Lync conversations with (not necessarily the most recent). Lync pre-populates this contact group with your team members.
You can “pin” your most important contacts to the top of Frequent Contacts by right-clicking the contact’s name and then clicking Pin to Frequent Contacts.
You need only point to a contact to receive rich information about that person or distribution group. You can start communicating from the contact card as well as from the Contacts list. When you expand the card, the information you see includes the contact’s organization.
Also, if you have Microsoft SharePoint services, searching for contacts is more comprehensive in Lync than it has been in the past. Because, in addition to being able to search for names or phone numbers, you now can search for items such as job title, department, or skills and expertise from a SharePoint profile.
Improved online meeting experience
Lync includes similar features as the online meeting functionality of Microsoft Office Live Meeting 2007, so now you can use a single program for instant messages and online meetings.
Meeting organizers now control who gets directly into a meeting and who waits in the lobby. Any presenter can admit or decline people who are waiting in the lobby.
Improved information sharing
Collaboration has never been better. Now you can:
•      Share your desktop or a program. Have a team editing session, or let a group see multiple windows on your desktop.
•      Show slides. Add a Microsoft PowerPoint presentation to the meeting, and give or collaborate on a presentation.
•      Write on a whiteboard. Take notes, or sketch ideas as a group.
•      Send files. Make hand-outs available to participants, or quickly send a document to one person.
•      Send and receive video. See participants from around the world at their desks. If you have Microsoft Lync 2010 Phone Edition for Polycom CX3000 / CX5000, you can see everyone around the remote conference-room table.
•      Record and play back meetings. Did someone miss the meeting? That person can see it later, in detail, using the Microsoft Silverlight browser plug-in. You can convert it to the Windows Media Player for easy distribution.
•      If you have contacts that aren’t in your company, don’t have Lync, or have Microsoft Communicator instead of Lync, they can still join your meeting. Just send them the standard e-mail meeting request, and they can join using Microsoft Lync Web App, in a web browser, or by downloading and installing Microsoft Lync 2010 Attendee. Lync Web App requires Silverlight and a phone for audio.
•      Lync features improved video controls and a full-screen online meeting experience, including support for panoramic, multipoint, and video, as well as VGA and HD video.
•      Lync can note your location and time zone information and share it with others. Additionally, location information might also be used for emergency services by routing emergency calls to the appropriate emergency response centre via the transmitted location.
•      Lync provides enhanced phone capabilities, with all the functions of a traditional phone system, plus useful productivity features, a new Voice over IP (VoIP) desktop phone is available with Lync Server 2010. The phone is designed to replace traditional phone systems (for example, the PBX system) in organizations. You can now see the number of missed calls and voice-mail messages, as well as place a test call to check the quality of your audio.
•      If you need other people to occasionally handle your calls, you can set them up to do so, and now they don’t need special software. Using Lync, a delegate can Make and receive calls, and schedule meetings, on behalf of someone
•      Limited Lync features are available in Microsoft Office 2003 and Office 2007, with many more available when you upgrade to the Office 2010 suite of programs.
•      Installation and identification of audio devices (such as telephones, headsets, and microphones) is easier than ever. Lync supports multiple devices, including Universal Serial Bus (USB) devices. Easily switch devices, even when you’re in a call.
















LYNC 2013 was introduced in October 11, 2012
Microsoft Lync is an enterprise-ready unified communications platform. Lync connects people everywhere, on Windows 8 and other operating systems including mobile devices, as part of their everyday productivity experience. Lync provides a consistent, single client experience for presence, instant messaging, voice, video and a great meeting experience. Lync users can connect to anyone on Skype, enabling rich communication with hundreds of millions of people around the world.
Lync Server Features

Work Anywhere
Lync allows users to communicate securely and stay connected with colleagues and customers, from virtually wherever they chose to work.
Lync across Devices
Users can switch among devices as they choose based on their needs. Lync offers familiar and consistent user experience across PC, phone, browser and tablets.
Simpler to Manage
Lync is a dependable platform for all real-time communications. A single system reduces complexity in Enterprise IT.
Exchange Archiving
Using the Exchange Online archiving, you can store all you emails, instant messages and Lync Online meeting contents, then easily search them using Exchange e-Discovery compliance.
New Front End Pools Architecture
In Lync Server 2013, the architecture of Enterprise Edition Front End pools has changed to a distributed systems architecture, with this new architecture, the Back End database is no longer the real-time data store in a pool. Information about a particular user is kept on three Front End Servers in the pool. For each user, one Front End Server acts as the master for that user’s information, and two other Front End Servers serve as replicas. If a Front End Server goes down, another Front End Server which served as a replica is automatically promoted to master.
This happens behind the scenes, and administrators do not need to know which Front End Servers are the masters for which users. This distribution of data storage improves performance and scalability within the pool, and eliminates the single point of failure of a single Back End Server.
The Back End Server serves as backup storage for user and conference data, and is also the primary storage for other databases such as the Response Group database.
Server Role Topology Changes
•      In Lync Server 2013, A/V Conferencing Server is always collocated with Front End Server.
•      In Lync Server 2013, Monitoring and Archiving are now always collocated with Front End Server but if you want it can be a part of backend also.
•       Persistent Chat Server is now a server role. In Microsoft Lync Server 2010, Group Chat Server was a third-party trusted application for Microsoft Lync Server 2010. In Lync Server 2013, Persistent Chat Server functionality is implemented using three new server roles:
o      PersistentChatService: Main Persistent Chat Server services implemented as a front end role
o      PersistentChatStore: Back End Server role
o      PersistentChatComplianceStore: Back End Server role for Persistent Chat Compliance
These Persistent Chat Server roles are optional, and are installed only by customers who want comprehensive Persistent Chat Server functionality. The PersistentChatComplianceStore role is needed only if you choose to deploy Persistent Chat Compliance.
The PersistentChatService role runs two services:
•      Persistent Chat service
•      Persistent Chat Compliance service
Having these services run on each Persistent Chat Server provides high availability for these services in a multiserver Persistent Chat Server pool.
 Important:
The PersistentChatService role can run on the same server as a Lync Server 2013 Front End Server only if that Front End Server is a Standard Edition Front End Server. The PersistentChatService role cannot run independently of a Lync Server 2013 Front End Server. It can be installed only in the context of a Lync Server 2013 deployment.

New disaster recovery and high availability features in Lync Server 2013
1.      As in Lync Server 2010, the main high availability (HA) scheme for Lync Server 2013 is based on server redundancy via pooling. If a server running a certain server role fails, the other servers in the pool running the same role take the load of that server. This applies to Front End Servers, Edge Servers, Mediation Servers, and Directors.
2.      Lync Server 2013 adds new disaster recovery measures by enabling you to pair Front End pools located in two datacenters. If one of the paired pools goes down, an administrator can fail over the users from that pool to the other pool in the pair, to provide continuation of service. This functionality does not require expensive network or hardware solutions such as storage networks or shared disks.
3.      Lync Server 2013 also adds Back End Server high availability. This is an optional topology in which you deploy two Back End Servers for a Front End pool, and set up synchronous SQL mirroring for all the Lync databases running on the Back End Servers. You may choose whether to deploy a witness for the mirror.
•      Directors are an optional role   the role of the Director server in the Lync Server 2013 topology has not changed. It still hosts web services, pre-authenticates incoming user requests, and directs external users to their home pool. Changing the Director from a recommended role to an optional role does not diminish the value of the Director, but emphasizes reducing server count and other hardware requirements (for example, hardware load balancers for the Director) requirements without compromising features and functionality. Because the Front End Servers can do the same job as the Director with no impact to services provided, you can optionally deploy Directors if you choose to. You can safely exclude the Director with confidence that the Front End Servers will provide the same services in their place.

•      Lync Server 2013 does not have a separate Monitoring Server role. Monitoring is an optional feature available on all Front End Servers in an Enterprise Edition deployment, and on Standard Edition servers, that can be implemented and configured for a pool or a site. else, you can enable SQL Server database mirroring for your Monitoring database.
New Archiving features in Lync Server 2013

•      Collocation of Archiving on Front End Servers.   Lync Server 2013 does not have a separate Archiving Server role. Archiving is an optional feature available on all Front End Servers in an Enterprise Edition deployment, and on Standard Edition servers, that can be implemented configured for a pool or a site.
•      Microsoft Exchange integration.   When you deploy Archiving, you can integrate data storage for Archiving with your existing Exchange 2013 storage for all users who are homed on Exchange 2013 and have their mailboxes put on In-Place Hold, so you don’t need to deploy separate SQL Server databases to archive Lync data. If you do not have an Exchange 2013 deployment, or if you prefer not to integrate with it, or if you have any Lync 2013 users who are not homed on Exchange 2013 with their mailboxes put on In-Place Hold, you can deploy separate Archiving databases by using SQL Server to store archived data from Lync communications. You can use both Microsoft Exchange integration and Lync Server 2013 Archiving databases if you want to use Microsoft Exchange integration for some but not all users in your deployment. You can use a unified contact store, in which the Lync contact list is stored in Exchange 2013, and you can manage the contact store in Lync 2013, Outlook 2013, and Outlook Web App.
•      You can use high-resolution photos for contacts. Photos with up to 648x648 pixels are stored in Exchange 2013 and made available to clients including Lync 2013, Outlook 2013, Microsoft Lync Web App, and Outlook Web App.
•      You can enable Lync Archiving integration, which integrates Lync Server 2013 Archiving into the Exchange 2013 In-Place Hold feature, for users homed on Exchange 2013, which enables one common experience for administrators around compliance and eDiscovery.

In Lync Server 2013, there are Compliance service modifications:
•      In Lync Server 2010, the Compliance service ran stand-alone (non-collocated), and only on a single server. The Compliance service now runs on all the Persistent Chat Server Front End Servers, alongside the Persistent Chat service, and thereby provides high availability in a multiserver Persistent Chat Server pool.
