Pre-announcement references

While officially announced on May 2nd, 2009, Valve had hinted prior to the release.

"Jarate: The Jar-Based Karate" Flyer

On April 1, 2009, Valve published a post on the TF2 Official Blog, A sneak preview of the next class update!, showing an order form for the Snipers new weapon, Jarate. However, due to the date of the posting (April Fool's Day), many believed the advertisement to be a joke.

Sniper Update Conformation

The next day, April 2, 2009, Valve published yet another post on the TF2 Official Blog, Wave goodbye to yer head, wanker, which confirmed that the Sniper was indeed the next class to be receiving an update. The post also hinted at 2 other updates, one that would be completed before the Sniper Updates release, and another that include some new content for all classes. These were later revealed to be the Spy update and the addition of hats respectively.

Sniper Primary Weapon Exploration

On May 5, 2009, Valve made a post titled You better hold onto your head, mate which explored the reasoning as to how the Snipers new primary weapon came about. It discussed that one of the main reasons for the unlock was due to players feeling hatred towards Snipers, as they were the cause of many deaths that were outside their area of engagement. The article concluded stating that the Snipers new unlock would promote the Sniper to move in closer to his enemies to give them a fighting chance.

Trivia

The Sniper vs. Spy Update also brought about the implementation of the item drop system. For a brief period, the new Sniper and Spy weapons were only obtainable through random drops, regardless of how many achievements had been completed. This was changed back just over a week later with the May 29, 2009 Patch which bought back the Milestone System in addition to the item drop system.
Sawmill (Arena) was the first map for TF2 created and released by Valve that contained an atmospheric effect with the introduction of ambient rain. Along with Pipeline, it was also one of the first official maps to take place at night.
